Full Context

configure filter ip-filter entry action l2-aware-nat-bypass

Description

This command enables bypassing NAT for packets pertaining to L2-Aware hosts and matching this entry. This action is only applicable to L2-Aware NAT subscribers and it must be configured together with action forward. Traffic identified in the match condition bypasses L2-Aware NAT. A common use case is to bypass NAT for on-net destinations (within the customer network).

Traffic that is not classified for bypass is automatically diverted to L2-Aware NAT, unless it is explicitly configured in the IP filter to be dropped.

For selective NAT bypass to take effect, in addition to the IP filter configuration, the L2-Aware NAT subscriber must be specifically enabled for selective bypass via the nat-allow-bypass configuration option in the NAT CLI node in the SLA profile.

The no form of this command automatically diverts traffic to L2-Aware NAT, unless it is explicitly configured in the IP filter to be dropped.

Full Context

configure system load-balancing l4-load-balancing

Description

This command configures system-wide Layer 4 load balancing. The configuration at the system level can enable or disable load balancing based on Layer 4 fields. If enabled, the Layer 4 source and destination port fields will be included in hashing calculation for TCP/UDP packets.

The hashing algorithm addresses finer spraying granularity where many hosts are connected to the network.

To address more efficient traffic distribution between network links (forming a LAG group), a hashing algorithm extension takes into account L4 information (that is, src/dst L4-protocol port).

The hashing index can be calculated according to the following algorithm:

Example:
    — If [(TCP or UDP traffic) & enabled] 
        — hash (TCP/UDP ports, IP addresses) 
    — else if (IP traffic) 
        — hash (IP addresses) 
    — else 
        — hash (MAC addresses)
    — endif

This algorithm will be used in all cases where IP information in per-packet hashing is included (refer to "Traffic Load Balancing Options" in the 7450 ESS, 7750 SR, 7950 XRS, and VSR Interface Configuration Guide). However, the Layer 4 information (TCP/UDP ports) will not be used for fragmented packets.

Description

This command sets ECMP multipath parameters that apply only to the label unicast IPv4 address family.

When multipath is enabled, traffic to the destination is load-shared across a set of paths (BGP routes) that the BGP decision process considers equal to the best path. The distribution of traffic over the multiple paths may or may not be equal. The distribution is based on weights derived from the Link Bandwidth Extended Community.

For more information about the criteria a non-best route must meet to qualify as a multipath, see "BGP route installation in the route table” in the 7450 ESS 7750 SR 7950 XRS VSR Unicast Routing Protocols User Guide.

The no form of this command removes label-IPv4-specific overrides.

Default

no label-ipv4

Parameters

max-paths

Specifies the maximum number of multipaths per prefix or NLRI. Setting this value to 1 disables multipath. This limit only applies if neither the ebgp-max-paths limit nor the ibgp-max-paths limit apply.

Values

1 to 64

ebgp-max-paths

Specifies the maximum number of multipaths per prefix or NLRI when the best path is an EBGP learned route. If the ebgp option is configured, this value overrides the max-paths limit. If the best path is an EBGP learned route and this value is set to 1, multipath is disabled.

Values

1 to 64

ibgp-max-paths

Specifies the maximum number of multipaths per prefix or NLRI when the best path is an IBGP learned route. If the ibgp option is configured, this value overrides the max-paths limit. If the best path is an IBGP learned route and this value is set to 1, multipath is disabled.

Values

Description

This command configures the add-paths capability for labeled-unicast IPv4 routes. By default, add-paths is not enabled for labeled-unicast IPv4 routes.

The maximum number of labeled-unicast paths per IPv4 prefix to send is the configured send-limit, which is a mandatory parameter. The capability to receive multiple labeled-unicast paths per prefix from a peer is configurable using the receive keyword, which is optional. If the receive keyword is not included in the command, receive capability is enabled by default.

The no form of this command disables add-paths support for labeled-unicast IPv4 routes, causing sessions established using add-paths for labeled-unicast IPv4 to go down and come back up without the add-paths capability.

Default

no label-ipv4

Parameters

send-limit

Specifies the maximum number of paths per labeled-unicast IPv4 prefix that are allowed to be advertised to add-paths peers. (The actual number of advertised routes may be less.) If the value is none, the router does not negotiate the send capability with respect to label-IPv4 AFI/SAFI. If the value is multipaths, then BGP advertises all the used BGP multipaths for each IPv4 NLRI if the peer has signaled support to receive multiple add paths.

Values

1 to 16, none, multipaths

receive

Specifies the router negotiates to receive multiple labeled-unicast routes per IPv4 prefix.

none

Specifies that the router does not negotiate to receive multiple labeled-unicast routes per IPv4 prefix.

This command configures the TTL propagation for locally generated packets which are forwarded over a BGP label route in the Global Routing Table (GRT) context.

For IPv4 and IPv6 packets forwarded using an RFC 8277 label route in the global routing instance, including 6PE, the all value of the command enables TTL propagation from the IP header into all labels in the transport label stack. The none value reverts to the default mode which disables TTL propagation from the IP header to the labels in the transport label stack. This command does not have a no version.

The TTL of the IP packet is always propagated into the RFC 8277 label itself, and this command only controls the propagation into the transport labels, for example, labels of the RSVP or LDP LSP to which the BGP label route resolves and which are pushed on top of the BGP label.

If the BGP peer advertised the implicit-null label value for the BGP label route, the TTL propagation will not follow the configuration described, but will follow the configuration to which the BGP label route resolves:

RSVP LSP shortcut:

  • configure router mpls shortcut-local-ttl-propagate

LDP LSP shortcut:

  • configure router ldp shortcut-local-ttl-propagate

This feature does not impact packets forwarded over BGP shortcuts. The ingress LER operates in uniform mode by default and can be changed into pipe mode using the configuration of TTL propagation for RSVP or LDP LSP shortcut listed.

Default

label-route-local none

Parameters

none

Specifies that the TTL of the IP packet is not propagated into the transport label stack.

all

Specifies that the TTL of the IP packet is propagated into all labels of the transport label stack.

configure router ldp label-withdrawal-delay

Description

This command specifies configures the time interval (in s), LDP will delay for the withdrawal of FEC-label binding it distributed to its neighbors when FEC is de-activated. When the timer expires, LDP then sends a label withdrawal for the FEC to all its neighbors. This is applicable only to LDP IPv4 prefix FECs and is not applicable to pseudowires (service FECs).

When there is an upper layer (user of LDP) which depends of LDP control plane for failover detection then label withdrawal delay and tunnel-down-damp-time options must be set to 0.

An example is PW redundancy where the primary PW doesn’t have its own fast failover detection mechanism and the node depends on LDP tunnel down event to activate the standby PW.

Default

no label-withdrawal-delay

Parameters

configure redundancy multi-chassis peer mc-lag lag

Description

This command defines a LAG which is forming a redundant-pair for MC-LAG with a LAG configured on the given peer. The same LAG group can be defined only in the scope of 1 peer. In order MC-LAG to become operational, all parameters (lacp-key, system-id, system-priority) must be configured the same on both nodes of the same redundant pair.

The partner system (the system connected to all links forming MC-LAG) will consider all ports using the same lacp-key, system-id, system-priority as the part of the same LAG. In order to achieve this in MC operation, both redundant-pair nodes have to be configured with the same values. In case of the mismatch, MC-LAG is kept in oper-down status.

Note that the correct CLI command to enable MC LAG for a LAG in standby-signaling power-off mode is lag lag-id [remote-lag remote-lag-id]. In the CLI help output, the first three forms are used to enable MC LAG for a LAG in LACP mode. MC LAG is disabled (regardless of the mode) for a given LAG with no lag lag-id.

Parameters

lag-id

The LAG identifier, expressed as an integer. Specifying the lag-id allows the mismatch between lag-id on redundant-pair. If no lag-id is specified it is assumed that neighbor system uses the same lag-id as a part of the specific MC-LAG. If no matching MC-LAG group can be found between neighbor systems, the individual LAGs operates as usual (no MC-LAG operation is established).

Values

1 to 800

admin-key

Specifies a 16 bit key that needs to be configured in the same manner on both sides of the MC-LAG in order for the MC-LAG to come up.

Values

1 to 65535

system-id

Specifies a 6 byte value expressed in the same notation as MAC address.

Values

xx:xx:xx:xx:xx:xx - xx [00 to FF]

remote-lag-id

Specifies the LAG ID on the remote system.

Values

1 to 800

system-priority

Specifies the system priority to be used in the context of the MC-LAG. The partner system will consider all ports using the same lacp-key, system-id, and system-priority as part of the same LAG.

Values

1 to 65535

MAC-Lsb

Configures the last 16 bit of the MAC address to be used for all traffic ingressing the MC-LAG link(s) or if use-lacp-key option is used, it will only copy the value of lacp-key (redundancy multi-chassis mc-lag lag lacp-key admin-key). The command will fail if the value is the same with any of the following configured attributes:

  • Source-bmac-lsb assigned to other MC-LAG ports.

  • lsb 16 bits value for the source-bmac configured at chassis or BVPLS level

    The first 32 bits will be copied from the source B-MAC of the BVPLS associated with the IVPLS for a specific IVPLS SAP mapped to the MC-LAG. The BVPLS source B-MAC can be provisioned for each BVPLS or can be inherited from the chassis PBB configuration.

Full Context

Description

Commands in this context configure Link Aggregation Group (LAG) attributes.

A LAG is used to group multiple ports into one logical link. The aggregation of multiple physical links allows for load sharing and offers seamless redundancy. If one link fails, traffic is redistributed over the remaining links.

Note:

For all ports in a LAG group, autonegotiation must be set to "limited” or "off”.

There are three possible settings for autonegotiation, as follows:

  • "on” or enabled with full port capabilities advertised

  • "off” or disabled where there is no autonegotiation advertisements

  • "limited” where a single speed/duplex is advertised.

When autonegotiation is enabled on a port, the link attempts to automatically negotiate the link speed and duplex parameters; the configured duplex and speed parameters are ignored.

When autonegotiation is disabled on a port, the port does not attempt to autonegotiate and will only operate at the speed and duplex settings configured for the port.

Note:

Disabling autonegotiation on gigabit ports is not allowed. This is in accordance with the IEEE 802.3 specification for gigabit Ethernet, which requires gigabyte to be enabled for far end fault indication.

If the config>port>ethernet autonegotiate limited keyword option is specified, the port will autonegotiate but only advertise the speed and duplex settings configured for the port. Use the limited mode on multi-speed gigabit ports to force gigabit operation while keeping autonegotiation is enabled for compliance with IEEE 801.3.

The system requires autonegotiation to be disabled or limited for ports in a LAG to guarantee a specific port speed.

The no form of this command deletes the LAG from the configuration. A LAG can only be deleted while the LAG is administratively shut down. Any dependencies, such as IP-Interface configurations, must be removed from the configuration before the no lag command is issued.

Parameters

lag-id

Specifies the LAG identifier, expressed as an integer.

The LAG ID ranging from 1 to 64 supports up to 64 LAG members and LAG ID above 64 supports 32 LAG members.

Values

1 to 800

lag-name

Specifies an optional LAG name, up to 27 characters.

In model-driven interfaces, the LAG name is used for configuration references and show commands. A service provider or administrator can use the defined LAG name to identify and manage LAGs within the SR OS platforms.

In the classic CLI interface, the user must assign a LAG ID to create the LAG. The LAG name is optional and, if specified, must always start with "lag-”. If a name is not specified, SR OS automatically assigns a string version of the LAG ID as "lag-<lag-id>”.

Full Context

configure vrrp policy priority-event lag-port-down

Description

This command creates the context to configure Link Aggregation Group (LAG) priority control events that monitor the operational state of the links in the LAG.

The lag-port-down command configures a priority control event. The event monitors the operational state of each port in the specified LAG. When one or more of the ports enter the operational down state, the event is considered to be set. When all the ports enter the operational up state, the event is considered to be clear. As ports enter the operational up state, any previous set threshold that represents more down ports is considered cleared, while the event is considered to be set.

Multiple unique lag-port-down event nodes can be configured within the priority-event node up to the maximum of 32 events.

The lag-port-down command can reference an arbitrary LAG. The lag-id does have to already exist within the system. The operational state of the lag-port-down event will indicate:

  • Set – non-existent

  • Set – one port down

  • Set – two ports down

  • Set – three ports down

  • Set – four ports down

  • Set – five ports down

  • Set – six ports down

  • Set – seven ports down

  • Set – eight ports down

  • Cleared – all ports up

When the lag-id is created, or a port in lag-id becomes operationally up or down, the event operational state must be updated appropriately.

When one or more of the LAG composite ports enters the operationally down state or the lag-id is deleted or does not exist, the event is considered to be set. When an event transitions from clear to set, the set is processed immediately and must be reflected in the associated virtual router instances in-use priority value. As the event transitions from clear to set, a hold-set timer is loaded with the value configured by the events hold-set command. This timer prevents the event from clearing until it expires, damping the effect of event flapping. If the event clears and becomes set again before the hold-set timer expires, the timer is reset to the hold-set value, extending the time before another clear can take effect.

The lag-port-down event is considered to have a tiered event set state. While the priority impact per number of ports down is totally configurable, as more ports go down, the effect on the associated virtual router instances in-use priority is expected to increase (lowering the priority). When each configured threshold is crossed, any higher thresholds are considered further event sets and are processed immediately with the hold-set timer reset to the configured value of the hold-set command. As the thresholds are crossed in the opposite direction (fewer ports down then previously), the priority effect of the event is not processed until the hold-set timer expires. If the number of ports down threshold again increases before the hold-set timer expires, the timer is only reset to the hold-setvalue if the number of ports down is equal to or greater than the threshold that set the timer.

The event contains number-down nodes that define the priority delta or explicit value to be used based on the number of LAG composite ports that are in the operationally down state. These nodes represent the event set thresholds. Not all port down thresholds must be configured. As the number of down ports increase, the number-down ports-down node that expresses a value equal to or less than the number of down ports describes the delta or explicit priority value to be applied.

The no form of the command deletes the specific LAG monitoring event. The event can be removed at anytime. When the event is removed, the in-use priority of all associated virtual router instances must be reevaluated. The events hold-set timer has no effect on the removal procedure.

Default

no lag-port-down — No LAG priority control events are created.

Parameters

lag-id

The LAG ID that the specific event is to monitor expressed as a decimal integer. The lag-id can only be monitored by a single event in this policy. The LAG may be monitored by multiple VRRP priority control policies. A port within the LAG and the LAG ID itself are considered to be separate entities. A composite port may be monitored with the port-down event while the lag-id the port is in is monitored by a lag-port-down event in the same policy.

Values

1 to 800 (apply to the 7750 SR and 7950 XRS)

Full Context

configure router pim lag-usage-optimization

Description

This command enables the router’s usage of the LAG so traffic for a given multicast stream destined to an IP interface using the LAG is sent only to the forwarding complex that owns the LAG link on which it will actually be forwarded.

Changing the value causes the PIM protocol to be restarted.

If this optimization is disabled, the traffic is sent to all forwarding complexes that own at least one link in the LAG.

The no form of this command causes the traffic to be sent to all the forwarding complexes that own at least one link in the LAG.

Note:

Changes made for multicast hashing cause Layer 4 multicast traffic to not be hashed. This is independent of if lag-usage-optimization is enabled or disabled.

Using this command and the mc-ecmp-hashing-enabled command on mixed port speed LAGs is not recommended, because some groups may be forwarded incorrectly.

Default

Description

This command configures the timer that specifies the wait time before the last reported delay measurement is flushed after a link measurement test enters the operationally down state. The aging timer delays the flushing of the last reported delay metric to the routing engine.

This timer starts a countdown to zero when an administrative function causes the operational state of the test on that specific interface to transition from up to down. If the timer expires before the operational state transitions to up, the previously reported value is flushed. The Delay Measurement Last Reported indicates "Cleared”. The timestamp indicates the time of the clear event. The Triggered By indicates "Expired”. If the administrative state recovers to operationally up before the expiration of the timer, the previous reported value is not flushed.

The aging timer does not apply to failure conditions that do not affect the administrative state of the interface, for example interface failure or routing changes.

The no form of this command reverts to the default value.

Default

last-reported-delay-hold 86400

Parameters

seconds

Specifies the delay measurement retention time, in seconds, after the interface on which it was collected is administratively disabled. If the configured value is reached, the last reported measurement is cleared.

A configured value of 0 indicates that the previous reported value is cleared without additional wait time.

Full Context

configure saa test latency-event

Description

Specifies that at the termination of an SAA test probe, the calculated latency event value is evaluated against the configured rising and falling latency event thresholds. SAA threshold events are generated as required.

Once the threshold (rising/falling) is crossed, it is disabled from generating additional events until the opposite threshold is crossed. If a falling-threshold is not supplied, the rising- threshold is re-enabled when it falls below the threshold after the initial crossing that generated the event.

The configuration of latency event thresholds is optional.

The no form of this command disables the latency event.

Parameters

rising-threshold threshold

Specifies a rising threshold latency value, in milliseconds. When the test run is completed, the calculated latency value is compared to the configured latency rising threshold. If the test run latency value is greater than the configured rising threshold value then an SAA threshold event is generated. The SAA threshold event is tmnxOamSaaThreshold, logger application OAM, event #2101.

Values

0 to 2147483

Default

0

falling-threshold threshold

Specifies a falling threshold latency value, in milliseconds. When the test run is completed, the calculated latency value is compared to the configured latency falling threshold. If the test run latency value is greater than the configured falling threshold value then an SAA threshold event is generated. The SAA threshold event is tmnxOamSaaThreshold, logger application OAM, event #2101.

Description

This command enables the MEP to process service activation streams encapsulated in ETH-CFM LBM frames that are directed to the MEP. The MEP will be allocated additional resources to rapidly respond to a high-speed stream of LBM messages.

A MEP created with this option will not validate any TLVs, will not validate the ETH-LBM MAC Address, and will not increment or compute any loopback statistics. Statistical computation and reporting is the responsibility of the test head-end. The ETH-CFM level of the high speed ETH-LBM stream must match the level of a MEP configured with this command. The high-speed stream must not target an ETH-CFM level that is not explicitly configured with this option. MEPs act as boundaries for lower levels, below the configured MEP level values. Those boundary levels do not inherit this function.

When the service activation test is complete, the MEP may be returned to standard processing by removing this command. If there is available bandwidth, the MEP will respond to other ETH-CFM PDUs, such as ETH-DMM marker packets, using standard processing.

The interaction between this command and the tools perform service id service-id loopback eth command must be carefully considered. It is recommended that either the lbm-svc-act-responder or the tools perform service id service-id loopback eth command be used at any given time within a service. If both commands must be configured, and the target reflection point is the MAC Swap Loopback function, the inbound stream of data must not include ETH-CFM traffic that is equal to or lower than the domain level of any configured MEP which would otherwise extract and process the ETH-CFM message. If the reflection target is a MEP configured with the lbm-svc-act-responder option, the mode (ingress or egress) of the SAP or SDP specified with this tools command and the MEP direction (up or down) must match when the functions are enabled on the same reflection point, and the domain level of the inbound ETH-LBM must be the same as that of the MEP configured with the lbm-svc-act-responder option. At no time should the two functions be conflicting with each other along the path of the stream. This conflict would lead to unpredictable and possibly destabilizing situations.

The no form of this command reverts to MEP LBM standard processing.

configure router interface eth-cfm mep lbm-svc-act-responder

Description

This command enables the MEP to process service activation streams encapsulated in ETH-CFM LBM frames that are directed to the MEP. The MEP will be allocated additional resources to rapidly respond to a high-speed stream of LBM messages. A MEP created with this option will not validate any TLVs, will not validate the ETH-LBM MAC Address, and will not increment or compute any loopback statistics. Statistical computation and reporting is the responsibility of the test head-end. The ETH-CFM level of the high speed ETH-LBM stream must match the level of a MEP configured with this command. It must not target any lower ETH-CFM level the MEP will terminate. When the service activation test is complete, the MEP may be returned to standard processing by removing this command. If there is available bandwidth, the MEP will respond to other ETH-CFM PDUs, such as ETH-DMM marker packets, using standard processing.

The interaction between this command and the tools perform service id service-id loopback eth command must be carefully considered. It is recommended that either the lbm-svc-act-responder or the tools perform service id service-id loopback eth command be used at any given time within a service. If both commands must be configured, and the target reflection point is the MAC Swap Loopback function, the inbound stream of data must not include ETH-CFM traffic that is equal to or lower than the domain level of any configured MEP which would otherwise extract and process the ETH-CFM message. If the reflection target is a MEP configured with the lbm-svc-act-responder option, the mode (ingress or egress) of the SAP or SDP specified with this tools command and the MEP direction (up or down) must match when the functions are enabled on the same reflection point, and the domain level of the inbound ETH-LBM must be the same as that of the MEP configured with the lbm-svc-act-responder option. At no time should the two functions be conflicting with each other along the path of the stream. This conflict would lead to unpredictable and possibly destabilizing situations.

The no form of this command reverts to MEP LBM standard processing.

configure router mpls lsp-template ldp-over-rsvp

Description

This command configures an LSP so that it can be used by the IGP to calculate its SPF tree.

When the ldp-over-rsvp option is also enabled in ISIS or OSPF, the IGP provides LDP with all ECMP IP next-hops and tunnel endpoints that it considers to be the lowest cost path to its destination.

IGP provides only the endpoints which are the closest to the destination in terms of IGP cost for each IP next-hop of a prefix. If this results in more endpoints than the ECMP value configured on the router, it will further prune the endpoints based on the lowest router-id and for the same router-id, it will select lowest interface-index first.

LDP then looks up the tunnel table to select the actual tunnels to the endpoint provided by IGP and further limits the endpoint selection to the ones which are the closest to destination across all the IP next-hops provided by IGP for a prefix. For each remaining endpoint, LDP selects a tunnel in a round-robin fashion until the router ECMP value is reached. For each endpoint, only tunnels with the same lowest metric are candidates. If more than one tunnel qualifies, the selection begins with the lowest tunnel-id.

Description

This command enables the resolution of IGP routes using LDP LSP across all network interfaces participating in the IS-IS and OSPF routing protocol in the system.

When LDP shortcut is enabled, LDP populates the routing table with next-hop entries corresponding to all prefixes for which it activated an LDP FEC. For a given prefix, two route entries are populated in the system routing table. One corresponds to the LDP shortcut next-hop and has an owner of LDP. The other one is the regular IP next-hop. The LDP shortcut next-hop always has preference over the regular IP next-hop for forwarding user packets and specified control packets over a given outgoing interface to the route next-hop.

All user and specified control packets for which the longest prefix match in RTM yields the FEC prefix will be forwarded over the LDP LSP.

When an IPv4 packet is received on an ingress network interface, a subscriber IES interface, or a regular IES interface, the lookup of the packet by the ingress forwarding engine will result in the packet being sent labeled with the label stack corresponding to the NHLFE of the LDP LSP when the preferred RTM entry corresponds to an LDP shortcut.

If the preferred RTM entry corresponds to an IP next-hop, the IPv4 packet is forwarded without a label.

When ECMP is enabled and multiple equal-cost next-hops exit for the IGP route, the ingress forwarding engine will spray the packets for this route based on hashing routine currently supported for IPv4 packets. When the preferred RTM entry corresponds to an LDP shortcut route, spraying will be performed across the multiple next-hops for the LDP FEC. The FEC next-hops can either be direct link LDP neighbors or T-LDP neighbors reachable over RSVP LSPs in the case of LDP-over-RSVP but not both.

When the preferred RTM entry corresponds to a regular IP route, spraying will be performed across regular IP next-hops for the prefix.

The no form of this command disables the resolution of IGP routes using LDP shortcuts.

Description

This command extends the LDP synchronization feature to a static route. When an interface comes back up, it is possible that a preferred static route using the interface as next-hop for a given prefix is enabled before the LDP adjacency to the peer LSR comes up on this interface. In this case, traffic on an SDP that uses the static route for the far-end address would be black-holed until the LDP session comes up and the FECs exchanged.

This option when enabled delays the activation of the static route until the LDP session comes up over the interface and the ldp-sync-timer configured on that interface has expired

configure router interface ldp-sync-timer

Description

This command enables synchronization of an IGP and LDP. When a link is restored after a failure, the IGP sets the link cost to infinity and advertises it. The actual value advertised in OSPF is 0xFFFF (65535). The actual value advertised in IS-IS regular metric is 0x3F (63) and in IS-IS wide-metric is 0xFFFFFE (16777214). This feature is not supported on RIP interfaces.

If an interface belongs to both IS-IS and OSPF, a physical failure will cause both IGPs to advertise an infinite metric and to follow the IGP-LDP synchronization procedures. If only one IGP bounces on this interface or on the system, then only the affected IGP advertises the infinite metric and follows the IGP-LDP synchronization procedures.

Next, an LDP Hello adjacency is brought up with the neighbor. The LDP synchronization timer is started by the IGP when the LDP session to the neighbor is up over the interface. This is to allow time for the label-FEC bindings to be exchanged.

When the LDP synchronization timer expires, the link cost is restored and is readvertised. The IGP will announce a new best next hop and LDP will use it if the label binding for the neighbor’s FEC is available.

If the user changes the cost of an interface, the new value is advertised at the next flooding of link attributes by the IGP. However, if the LDP synchronization timer is still running, the new cost value will only be advertised after the timer expires. The new cost value will also be advertised after the user executes any of the following commands:

  • tools>perform>router>isis>ldp-sync-exit

  • tools>perform>router>ospf>ldp-sync-exit

  • config>router>if>no ldp-sync-timer

  • config>router>ospf>disable-ldp-sync

  • router>isis>disable-ldp-sync

If the user changes the value of the LDP synchronization timer parameter, the new value will take effect at the next synchronization event. If the timer is still running, it will continue to use the previous value.

If parallel links exist to the same neighbor, then the bindings and services should remain up as long as there is one interface that is up. However, the user-configured LDP synchronization timer still applies on the interface that failed and was restored. In this case, the router will only consider this interface for forwarding after the IGP re-advertises its actual cost value.

The LDP Sync Timer State is not always synchronized across to the standby CPM. Therefore, after an activity switch, the timer state might not be same as it was on the previously active CPM.

If the end-of-lib option is configured, then the system will start the LDP synchronization timer as usual. If the LDP End of LIB Typed Wildcard FEC messages are received for every FEC type negotiated for a given session to an LDP peer for that IGP interface, the ldp-sync-timer is terminated early and the IGP link cost is restored. If the ldp-sync-timer expires before the LDP End of LIB messages are received for every negotiated FEC type, then the system will restore the IGP link cost. The end-of-lib option is disabled by default.

The no form of this command disables IGP-LDP synchronization and deletes the configuration.

Default

no ldp-sync-timer

Values

downstream-map-tlv {dsmap | ddmap}

Specifies which format of the downstream mapping TLV to use in the LSP trace packet. The DSMAP TLV is the original format in RFC 4379 (obsoleted by RFC 8029). The DDMAP is the new enhanced format specified in RFC 6424 and RFC 8029.

Default

Inherited from global configuration of downstream mapping TLV in option mpls-echo-request-downstream-map {dsmap | ddmap}.

fc-name

Specifies the FC and profile parameters are used to indicate the forwarding class and profile of the MPLS echo request packet.

When an MPLS echo request packet is generated in CPM and is forwarded to the outgoing interface, the packet is queued in the egress network queue corresponding to the specified FC and profile parameter values. The marking of the packet's EXP is dictated by the LSP-EXP mappings on the outgoing interface.

When the MPLS echo request packet is received on the responding node, The FC and profile parameter values are dictated by the LSP-EXP mappings of the incoming interface.

When an MPLS echo reply packet is generated in CPM and is forwarded to the outgoing interface, the packet is queued in the egress network queue corresponding to the FC and profile parameter values determined by the classification of the echo request packet, which is being replied to, at the incoming interface. The marking of the packet's EXP is dictated by the LSP-EXP mappings on the outgoing interface. The ToS byte is not modified. ldp-treetrace Request Packet and Behavior summarizes this behavior.

configure router leak-export

Description

This command associates up to four policies to control the leaking of GRT routes into the associated VPRN.

If a route is evaluated and the action is accepted, that route is subject leaking into an associated VPRN instance, assuming the route is fully resolved and active.

This process creates the pool of routes that can be leaked. Within each VPRN, a corresponding import-grt policy must be configured to import select routes into that specific VPRN instance.

The no form of this command removes all route leaking policy associations and effectively disables the leaking of GRT routes into associated VPRNs.

Parameters

plcy-or-long-expr

Specifies the route policy name, up to 64 characters or a policy logical expression, up to 255 characters.

Values

plcy-or-long-expr: policy-name | long-expr

policy-name: up to 64 characters

long-expr: up to 255 characters

plcy-or-expr

Specifies the route policy name, up to 64 characters or a policy logical expression, up to 64 characters long. A maximum of four policy names or policy logical expressions can be specified in a single statement.

Description

This command configures route policies that control the importation of leak-eligible routes from the BGP RIB of another routing instance into the unlabeled-IPv4, unlabeled-IPv6, labeled-IPv4, or labeled-IPv6 RIB of the VPRN instance. To leak a route from one routing instance to another, the origin and destination RIB types must be the same; for example, it is not possible to leak a route from an unlabeled-IPv4 RIB of a VPRN into the labeled-IPv4 RIB of the base router.

The leak-import command can reference up to 15 objects, where each object is either a policy logical expression or the name of a single policy. The objects are evaluated in the specified order to determine the final action to accept or reject the route.

Only one of the 15 objects referenced by the leak-import command can be a policy logical expression consisting of policy names (enclosed in square brackets) and logical operators (AND, OR, NOT). The first of the 15 objects has a maximum length of 255 characters while the remaining 14 objects have a maximum length of 64 characters each.

When a leak-import policy is not specified, no BGP routes from other routing instances are leaked into the VPRN BGP RIB.

The no form of this command removes the policy association.

Default

no leak-import

Parameters

plcy-or-long-expr

Specifies the route policy name (up to 64 characters) or a policy logical expression (up to 255 characters). Allowed values are any string of characters composed of printable, 7-bit ASCII characters. If the string contains special characters (#, $, spaces, and so on), the entire string must be enclosed within double quotes.

Description

This command enables the sending of ARP or ND packets on the WLAN-GW GRE tunnel for certain events. The target IP address in the ARP/ND packet is the endpoint IP address of the AP. The ARP/ND response from the AP should contain the AP MAC, which subsequently can be reported in a called-station-id message. When enabled, a message will be sent for following events:

  • CPM: Mobility to an AP for which the AP-MAC is not yet known

  • CPM: RS-triggered authentication on an AP for which the AP-MAC is not yet known

  • ISA: Any mobility event

  • ISA: Any authentication where the AP-MAC is not yet known (for example, from a RADIUS proxy cache or a DHCP circuit-id). If the optional keyword delay-auth is configured, then the authentication will be delayed until the ARP/ND is answered or timed out, after which the AP-MAC can be included in the authentication.

This configuration is ignored for L2-AP and L2TPv3 access.

Parameters

delay-auth

Specifies that authentication will be delayed until the ARP/ND is answered or timed out, after which the AP-MAC can be included in the authentication.

Description

Commands in this context configure IPoE host parameters.

For VPLS, DHCP snooping must be explicitly enabled (using the snoop command) at all points where DHCP messages requiring snooping enter the VPLS instance (both from the DHCP server and from the subscribers). Lease state information is extracted from snooped DHCP ACK messages to populate lease state table entries for the SAP.

The optional nbr-of-leases parameter defines the number lease state table entries allowed.

  • for this SAP in case of a VPLS service

  • for this interface in case of an IES or VPRN interface

  • for each SAP in case of an IES or VPRN group-interface

  • for this interface in case of an IES or VPRN retail subscriber-interface

If the nbr-of-leases parameter is omitted, only a single entry is allowed. Once the maximum number of entries has been reached, subsequent lease state entries are not allowed and subsequent DHCP ACK messages are discarded.

The retained lease state information representing dynamic hosts may be used to:

  • Populate a SAP based anti-spoof filter table to provide dynamic anti-spoof filtering. If the system is unable to populate the dynamic host information in the anti-spoof filter table on the SAP, the DHCP ACK message must be discarded without adding new lease state entry or updating an existing lease state entry.

  • Populate the system’s ARP cache based on the arp-populate configuration. Applicable to IES and VPRN interfaces or group-interfaces.

  • Populate managed entries into a VPLS forwarding database. VPLS forwarding database population is an implicit feature that automatically places the dynamic host’s MAC address into the VPLS FDB. When a dynamic host’s MAC address is placed in the lease state table, it will automatically be populated into the VPLS forwarding database associated with the SAP on which the host is learned. The dynamic host MAC address will override any static MAC entries using the same MAC and prevent dynamic learning of the MAC on another interface. Existing static MAC entries with the same MAC address as the dynamic host are marked as inactive but not deleted. If all entries in the lease state table associated with the MAC address are removed, the static MAC may be populated. New static MAC definitions for the VPLS instance may be created while a dynamic host exists associated with the static MAC address.

  • Generate dynamic ARP replies if arp-reply-agent is enabled. Applicable to VPLS service SAPs

The no form of this command reverts to the default.

Parameters

nbr-of-leases

Specifies the number of DHCPv4 leases allowed.

l2-header

Indicates a mode of operation where anti-spoof entry associated with the given DHCP state is created based on the src-mac address from the Layer 2 header of the DHCP request message. The Layer 2 header flag is not set by default. This parameter is only applicable for group interfaces.

mac

Specifies that the provisioned ieee-address is used in the anti-spoofing entries for this SAP. The parameter may be changed mid-session. Existing sessions will not be re-programmed unless a tools>perform>subscriber-mgmt>remap-lease-state command is issued for the lease. This parameter is only applicable for group interfaces.

Full Context

configure router mpls lsp-template least-fill

configure router mpls lsp least-fill

Description

This command enables the use of the least-fill path selection method for the computation of the path of this LSP.

When MPLS requests the computation of a path for this LSP, CSPF will find all equal cost shortest paths which satisfy the constraints of this path. Then, CSPF identifies the single link in each of these paths which has the least available bandwidth as a percentage of its maximum reservable bandwidth. It then selects the path which has the largest value of this percentage least available bandwidth figure. CSPF identifies the least available bandwidth link in each equal cost path after it has accounted for the bandwidth of the new requested path of this LSP.

CSPF applies the least-fill path selection method to all requests for a path, primary and secondary, of an LSP for which this option is enabled. The bandwidth of the path can be any value, including zero.

CSPF applies the least-fill criterion separately to each preemption priority in the base TE. A higher setup priority path can preemptively lower holding priority paths.

CSPF also applies the least-fill criterion separately to each Diff-Serv TE class if Diff-Serv TE is enabled on this node. A higher setup priority path can preemptively lower holding priority paths within a Class Type.

MPLS will re-signal and move the LSP to the new path in the following cases:

  • Initial LSP path signaling.

  • Re-try of an LSP path after failure.

  • Make-before-break (MBB) due to pending soft preemption of the LSP path.

  • MBB due to LSP path configuration change, that is, a user change to bandwidth parameter of primary or secondary path, or a user enabling of fast-reroute option for the LSP.

  • MBB of secondary path due to an update to primary path SRLG.

  • MBB due to FRR Global Revertive procedures on the primary path.

  • Manual re-signaling of an LSP path or of all LSP paths by the user.

During a manual re-signaling of an LSP path, MPLS will always re-signal the path regardless of whether the new path is exactly the same or different than the current path and regardless of whether the metric of the new path is different or not from that of the current path.

During a timer-based re-signaling of an LSP path which has the least-fill option enabled, MPLS will only re-signal the path if the metric of the new path is different than the one of the current path.

The no form of this command deletes a specific node entry in this database.

Default

no least-fill. The path of an LSP is randomly chosen among a set of equal cost paths.

Description

This parameter is used in the least-fill path selection process. When comparing the percentage of least available link bandwidth across the sorted paths, whenever two percentages differ by less than the value configured as the least-fill-min-thresh, CSPF will consider them equal and will apply a random number generator to select the path among these paths

configure router mpls least-fill-reoptim-thd

Description

This parameter is used in the least-fill path selection method. During a timer-based re-signaling of an LSP path which has the least-fill option enabled, CSPF will first update the least-available bandwidth figure for the current path of this LSP. It then applies the least-fill path selection method to select a new path for this LSP. If the new computed path has the same cost as the current path, it will compare the least-available bandwidth figures of the two paths and if the difference exceeds the user configured optimization threshold, MPLS will generate a trap to indicate that a better least-fill path is available for this LSP. This trap can be used by an external SNMP based device to trigger a manual re-signaling of the LSP path since the timer-based re-signaling will not re-signal the path in this case. MPLS will generate a path update trap at the first MBB event which results in the re-signaling of the LSP path. This should clear the eligibility status of the path at the SNMP device.

The no form of this command resets this parameter to its default value.

Description

This command controls the period of time that the Registrar state machine will wait in the leave state before transitioning to the MT (Empty) state when it is removed. An instance of the timer is required for each state machine that is in the leave state. The leave period timer is set to the value specified for leave-time when it is started.

A registration is normally in an "in” state where there is an MFIB entry and traffic is being forwarded. When a "leave all” is performed (periodically around every 10-15 seconds per SAP/SDP binding - see leave-all-time-below), a node sends a message to its peer indicating a leave all is occurring and puts all of its registrations in leave state.

The peer refreshes its registrations based on the leave all PDU it receives and sends a PDU back to the originating node with the state of all its declarations.

Refer to IEEE 802.1ak-2007 section 10.7.4.2.

Description

This command is used to enable tunnel QoS mapping on all ingress network IP interfaces that the network-qos-policy-id is associated with. The command may be defined at any time after the network QoS policy has been created. Any network IP interfaces currently associated with the policy will immediately start to use the internal IP ToS field of any tunnel terminated IP routed packet received on the interface, ignoring any QoS markings in the tunnel portion of the packet.

This attribute provides the ability to ignore the network ingress QoS mapping of a terminated tunnel containing an IP packet that is to be routed to a base router or VPRN destination. This is advantageous when the mapping for the tunnel QoS marking does not accurately or completely reflect the required QoS handling for the IP routed packet. When the mechanism is enabled on an ingress network IP interface, the IP interface will ignore the tunnel’s QoS mapping and derive the internal forwarding class and profile based on the precedence or DiffServ Code Point (DSCP) values within the routed IP header ToS field compared to the Network QoS policy defined on the IP interface.

The default state is not to enforce tunnel termination IP routed QoS override within the network QoS policy.

The no form of this command removes tunnel termination IP routed QoS override from the network QoS policy and all ingress network IP interfaces associated with the policy.

Description

This command allows a CIDR shortest match hit on a route prefix that contains the IP route prefix associated with the route unknown priority event.

The less-specific command modifies the search parameters for the IP route prefix specified in the route-unknown priority event. Specifying less-specific allows a CIDR shortest match hit on a route prefix that contains the IP route prefix.

The less-specific command eases the RTM lookup criteria when searching for the prefix/mask-length. When the route-unknown priority event sends the prefix to the RTM (as if it was a destination lookup), the result route table prefix (if a result is found) is checked to see if it is an exact match or a less specific match. The less-specific command enables a less specific route table prefix to match the configured prefix. When less-specific is not specified, a less specific route table prefix fails to match the configured prefix. The allow-default optional parameter extends the less-specific match to include the default route (0.0.0.0).

The no form of the command prevents RTM lookup results that are less specific than the route prefix from matching.

Default

no less-specific — The route unknown priority events requires an exact prefix/mask match.

Parameters

allow-default

When the allow-default parameter is specified with the less-specific command, an RTM return of 0.0.0.0 matches the IP prefix. If less-specific is entered without the allow-default parameter, a return of 0.0.0.0 will not match the IP prefix. To disable allow-default, but continue to allow less-specific match operation, only enter the less-specific command (without the allow-default parameter).

Full Context

configure qos port-scheduler-policy level

Description

This command configures an explicit within-CIR bandwidth limit and a total bandwidth limit for each port scheduler’s priority level. To understand how to set the level rate and CIR parameters, a basic understanding of the port-level scheduler bandwidth allocation mechanism is required. The port scheduler takes all available bandwidth for the port or channel (after the max-rate and any port egress-rate limits have been accounted for) and offers it to each of the eight priority levels twice.

The first pass is called the within-CIR pass and consists of providing the available port bandwidth to each of the 8 priority levels, starting with level 8 and moving down to level 1. Each level takes the offered load and distributes it to all child members that have a port-parent cir-level equal to the current priority level. (Any child with a cir-weight equal to 0 is skipped in this pass.) Each child may consume bandwidth up to the child’s frame-based within-CIR offered load. The remaining available port bandwidth is then offered to the next lower priority level until level 1 is reached.

The second pass is called the above-CIR pass and consists of providing the remaining available port bandwidth to each of the eight priority levels a second time. Again, each level takes the offered load and distributes it to all child members that have a port-parent level equal to the current priority level. Each child may consume bandwidth up to the remainder of the child’s frame-based offered load (some of the offered load may have been serviced during the within-CIR pass). The remaining available port bandwidth is then offered to the next priority level until level 1 is again reached.

If the port scheduling policy is using the default orphan behavior (orphan-override has not been configured on the policy), the system then takes any remaining port bandwidth and allocates it to the orphan queues and scheduler on priority level 1. In a non-override orphan state, all orphans are attached to priority level 1 using a weight of 0. The zero weight value causes the system to allocate bandwidth equally to all orphans based on each orphan queue or scheduler’s ability to use the bandwidth. If the policy has an orphan-override configured, the orphans are handled based on the override commands parameters in a similar fashion to properly parented queues and schedulers.

The port scheduler priority level command rate keyword is used to optionally limit the total amount of bandwidth that is allocated to a priority level (total for the within-CIR and above-CIR passes). The cir keyword optionally limits the first pass bandwidth allocated to the priority level during the within-CIR pass.

When executing the level command, at least one of the optional keywords, rate or cir, must be specified. If neither keyword is included, the command will fail.

If a previous explicit value for rate or cir exists when the level command is executed, and either rate or cir is omitted, the previous value for the parameter is overwritten by the default value and the previous value is lost.

The configured priority level rate limits may be overridden at the egress port or channel using the egress-scheduler-override level priority-level command. When a scheduler instance has an override defined for a priority level, both the rate and cir values are overridden even when one of them is not explicitly expressed in the override command. For instance, if the cir kilobits per second portion of the override is not expressed, the scheduler instance defaults to not having a CIR rate limit for the priority level even when the port scheduler policy has an explicit CIR limit defined.

The no form of this command returns the level to its default value.

Default

no level priority-level

Parameters

priority-level

Specifies to which priority level the level command pertains. Each of the eight levels is represented by an integer value of 1 to 8, with 8 being the highest priority level.

Values

1 to 8 (8 is the highest priority)

pir-rate

Specifies the total bandwidth limits allocated to priority-level, in kilobits per second.

Values

1 to 6400000000, max

pir-percent

Specifies the percent bandwidth limits allocated to priority-level.

Values

0.01 to 100.00

cir-rate

The cir specified limits the total bandwidth allocated in the within-CIR distribution pass to priority-level. When cir is not specified, all the available port or channel bandwidth may be allocated to the specified priority level during the within-CIR pass.

Values

0 to 6400000000, max

The value given for kilobits per second is expressed in kilobits per second on a base 10 scale as is usual for line rate calculations. If a value of 1 is given, the result is 1000 bits per second (as opposed to a base 2 interpretation that would be 1024 bits per second).

cir-percent

Specifies the percent bandwidth limits allocated to priority-level.

Values

0.00 to 100.00

group name

specifies the existing group that the weighted scheduler group this level maps to, up to 32 characters.

weight

Specifies the weight of the level within this weighted scheduler group.

Values

1 to 100

Default

configure router isis interface level

Description

This command creates the context to configure IS-IS Level 1 or Level 2 area attributes.

A router can be configured as a Level 1, Level 2, or Level 1/2 system. A Level 1 adjacency can be established if there is at least one area address shared by this router and a neighbor. A Level 2 adjacency cannot be established over this interface.

Level 1/2 adjacency is created if the neighbor is also configured as Level 1/2 router and has at least one area address in common. A Level 2 adjacency is established if there are no common area IDs.

A Level 2 adjacency is established if another router is configured as Level 2 or a Level 1/2 router with interfaces configured as Level 1/2 or Level 2. Level 1 adjacencies are not established over this interface.

To reset global and/or interface level parameters to the default, the following commands must be entered independently:

— level>no hello-authentication-key
    — level>no hello-authentication-type
    — level>no hello-interval
    — level>no hello-multiplier

Description

This command applies a route next-hop policy template to the IS-IS interface for the VPRN instance.

When a route next-hop policy template is applied to an interface in IS-IS, it is applied in both level 1 and level 2. When a route next-hop policy template is applied to an interface in OSPF, it is applied in all areas. However, the command in an OSPF interface context can only be executed under the area in which the specified interface is primary and then applied in that area and in all other areas where the interface is secondary. If the user attempts to apply it to an area where the interface is secondary, the command fails.

If the user excluded the interface from LFA using the command loopfree-alternate-exclude, the LFA policy, if applied to the interface, has no effect.

Finally, if the user applied a route next-hop policy template to a loopback interface or to the system interface, the command will not be rejected, but it will result in no action being taken.

The no form deletes the mapping of a route next-hop policy template to an OSPF or IS-IS interface.

Specifies the intercept-id that is inserted into the packet header for all mirrored packets of the associated li-source entry. This intercept ID can be used (for example by a downstream LI gateway) to identify the particular LI session to which the packet belongs. For all types of li-source entries (filter, nat, sap, subscriber), when the mirror service is configured with ip-udp-shim routable encap, an intercept-id field (as part of the routable encap) is always present in the mirrored packets. If there is no intercept-id configured for an li-source entry, then the default value will be inserted. When the mirror service is configured with ip-gre or ip-udp-shim-sampled routable encap, no intercept ID is inserted and none can be specified against the li-source entries.

session-id

Specifies the session-id that is inserted into the packet header for all mirrored packets of the associated li-source entry. This session-id can be used (for example by a downstream LI Gateway) to identify the particular LI session to which the packet belongs. The session-id is only valid and used for mirror services that are configured with ip-udp-shim routable encap (config>mirror>mirror-dest>encap>ip-udp-shim). For all types of li-source entries (filter, nat, sap, or subscriber), when the mirror service is configured with ip-udp-shim routable encap, a session-id field (as part of the routable encap) is always present in the mirrored packets. If there is no session-id configured for an li-source entry, then the default value will be inserted. When a mirror service is configured with ip-gre or ip-udp-shim-sampled routable encap, no session-id is inserted and none can be specified against the li-source entries.

configure li li-source li-ipv6-filter

Description

This command enables lawful interception (LI) of packets that match specific entries in an existing LI IPv6 filter that has been associated with a normal IPv6 filter. The specification of an li-ipv6-filter entry as an li-source means that packets matching the li-ipv6-filter entry will be intercepted on all interfaces/saps/and so on, where the associated normal ip-filter(s) are applied.

Parameters

li-filter-name

Specifies the name of the li-ipv6-filter up to 32 characters.

li-entry-id

Specifies the entry ID in the li-ipv6-filter that is to be used as an LI source criteria.

Values

1 to 65535

intercept-id

Specifies the intercept ID that is inserted into the packet header for all mirrored packets of the associated li-source entry. This intercept-id can be used (for example by a downstream LI gateway) to identify the particular LI session to which the packet belongs. For all types of li-source entries (filter, nat, sap, or subscriber), when the mirror service is configured with ip-udp-shim routable encap, an intercept-id field (as part of the routable encapsulation) is always present in the mirrored packets. If there is no intercept-id configured for an li-source entry, then the default value will be inserted. When the mirror service is configured with ip-gre or ip-udp-shim-sampled routable encap, no intercept ID is inserted and none can be specified against the LI source entries.

session-id

Specifies the session ID that is inserted into the packet header for all mirrored packets of the associated li-source entry. This session-id can be used (for example, by a downstream LI gateway) to identify the particular LI session to which the packet belongs. The session-id is only valid and used for mirror services that are configured with ip-udp-shim routable encap (config>mirror>mirror-dest>encap>ip-udp-shim). For all types of li-source entries (filter, nat, sap, subscriber), when the mirror service is configured with ip-udp-shim routable encap, a session-id field (as part of the routable encap) is always present in the mirrored packets. If there is no session ID configured for an li-source entry, then the default value is inserted. When a mirror service is configured with ip-gre or ip-udp-shim-sampled routable encap, no session ID is inserted and none can be specified against the li-source entries.

Description

This command creates a Lawful Interception (LI) MAC filter list, or enters the CLI context for a LI MAC filter list. LI MAC filters are used as a manner to create confidential MAC filter based li-source entries. The LI MAC filter entries are inserted/merged into normal MAC filters as configured via the li-filter-associations and li-filter-block-reservation commands, but the LI MAC filter entries are not visible to users without LI permissions.

The no form of this command removes the MAC LI filter name from the configuration.

Parameters

Description

This command specifies whether or not a non-LI user has access to lawful intercept (LI) information. When this command is enabled, a user who does not have LI access will not be allowed to access CLI or SNMP objects in the li context. Modifying this command will not take effect until the system is rebooted.

When the no li-separate command is set (the default mode), those who are allowed access to the config>system>security>profile context and user command nodes are allowed to modify the configuration of the LI parameters. In this mode, a user that has a profile allowing access to the config>li and/or show>li command contexts can enter and use the commands under those nodes.

When the li-separate command is configured, only users that have the LI access capabilities set in the config>system>security>user>access li context are allowed to access the config>li and/or show>li command contexts. A user who does not have LI access is not allowed to enter the config>li and show>li contexts even though they have a profile that allows access to these nodes. When in the li-separate mode, only users with config>system>security>user>access li set in their user account have the ability modify the setting LI parameters in either their own or other profiles and user configurations.

Description

This command is used to configure the system to use the minimum configurable PIR instead of an H-QoS derived zero operational PIR. The default behavior is to allow the operational PIR of the queue to remain the last configured value while setting the queue MBS to zero (preventing queuing of newly arriving packets). Retaining the previous PIR value may cause a momentary burst above an aggregate rate associated with the queue as it drains. Using the limit-pir-zero-drain command causes the queue to drain at the lowest rate possible (typically 1 kb/s) that limits overrun situations.

The no form of this command reverts to default behavior.

Description

This command enables Link Loss Forwarding (LLF) on an Ethernet port. This feature provides an end-to-end OAM fault notification for Ethernet VLL service. It brings down the Ethernet port (Ethernet LLF) or sends a SONET/SDH Path AIS (ATM LLF) toward the attached CE when there is a local fault on the Pseudowire or service, or a remote fault on the SAP or pseudowire, signaled with label withdrawal or T-LDP status bits. It ceases when the fault disappears.

The Ethernet port must be configured for null encapsulation.

This feature is also supported in Epipes with BGP-EVPN enabled. In this case, upon removal of the EVPN destination, the port is brought oper-down with flag LinkLossFwd, however the AD per-EVI route for the SAP is still advertised (the SAP is kept oper-up).

The no form of this command disables LLF on an Ethernet port.

Description

This command is applicable only to LNS. By default traffic load balancing between the BB-ISAs is based on sessions. Each session is individually assigned to an BB-ISA during session establishment phase.

By introducing MLPPPoX, all sessions of a bundle must be terminated on the same LNS BB-ISA. This is necessary for two reasons:

  • QoS in the carrier IOM has a uniform view of the subscriber

  • a single BB-ISA is responsible for MLPPPoX encapsulation/fragmentation for a given bundle.

Therefore, if fragmentation is enabled, load-balancing per tunnel must be configured. In the per tunnel load-balancing mode, all sessions within the same tunnel are terminated on the same LNS BB-ISA.

In the case that we have MLPPPoX sessions with a single member link, both load-balancing methods are valid.

The no form of this command reverts to the default.

Default

load-balance-method per-session

Parameters

per-session

Specifies that the traffic load balancing between the LNS BB-ISAs is based on individual PPPoE sessions.

per-tunnel

Specifies that the traffic load balancing between the LNS BB-ISAs is based on tunnels.

Description

This command specifies the load balancing algorithm to be used on this port.

In the default mode, no load-balancing-algorithm, the port inherits the global settings. The value is not applicable for ports that do not pass any traffic.

The configuration of load-balancing-algorithm at logical port level has three possible values:

  • include-l4 — Enables inherits system-wide settings including Layer 4 source and destination port value in hashing algorithm.

  • exclude-l4 — Layer 4 source and destination port value will not be included in hashing.

  • no load-balancing-algorithm — Inherits system-wide settings.

The hashing algorithm addresses finer spraying granularity where many hosts are connected to the network. To address more efficient traffic distribution between network links (forming a LAG group), a hashing algorithm extension takes into account Layer 4 information (src/dst L4-protocol port). The hashing index can be calculated according to the following algorithm:

If [(TCP or UDP traffic) & enabled]

hash (<TCP/UDP ports>, <IP addresses>)

else if (IP traffic)

hash (<IP addresses>)

else

hash (<MAC addresses>)

endif

This algorithm will be used in all cases where IP information in per-packet hashing is included (refer to "Traffic Load Balancing Options” in the 7450 ESS, 7750 SR, 7950 XRS, and VSR Interface Configuration Guide). However the Layer 4 information (TCP/UDP ports) will not be used in the following cases:

  • fragmented packets

Default

no load-balancing-algorithm

Parameters

option

Specifies the load balancing algorithm to be used on this port.

Values

include-l4 — Specifies that the source and destination ports are used in the hashing algorithm.exclude-l4 — Specifies that the source and destination ports are not used in the hashing algorithm.

Description

This command configures a weighted ECMP load-balancing weight for a static route next-hop.

If all of the ECMP next-hops of a static route have a configured load-balancing-weight then packets matching the route are sprayed according to the relative weights. In other words, the next-hop interface with the largest load-balancing weight should receive the most forwarded traffic if weighted ECMP is applicable.

The no form of this command disables weighted ECMP for the interface and effectively disables weighted ECMP for the entire static route.

Description

This command configures the weighted ECMP load-balancing weight for an IS-IS, OSPF, and OSPF3 interface. If the interface becomes an ECMP next hop for an IPv4 or IPv6 route, and all the other ECMP next hops are interfaces with configured (non-zero) load-balancing weights, then the traffic distribution over the ECMP interfaces is proportional to the weights. This means that the interface with the largest load-balancing weight receives the most forwarded traffic if weighted ECMP is applicable.

The no form of this command disables weighted ECMP for the interface which effectively disables weighted ECMP for any IP prefix that has this interface as a next hop.

Description

This command configures the local end of a Multicast Source Discovery Protocol (MSDP) session. For MSDP to function, at least one peer must be configured. When configuring a peer, you must include this local-address command to configure the local end of the MSDP session. This address must be present on the node and is used to validate incoming connections to the peer and to establish connections to the remote peer.

If the user enters this command, then the address provided is validated and will be used as the local address for MSDP peers from that point. If a subsequent local-address command is entered, it will replace the existing configuration and existing sessions will be terminated.

Similarly, when the no form of this command is entered, the existing local address will be removed from the configuration and the existing sessions will be terminated.

Whenever a session is terminated, all information pertaining to and learned from that peer will be removed.

Whenever a new peering session is created or a peering session is lost, an event message should be generated.

configure router pcep pcc local-address

Description

This command configures the local IPv4 address of the PCEP speaker.

The PCEP protocol operates over TCP using destination TCP port 4189. The PCE client (PCC) always initiates the connection. After the user configures the PCEP local IPv4 address and the peer IPv4 address on the PCC, the latter initiates a TCP connection to the PCE. If both a local IPv4 and a local IPv6 address are configured, the connection uses the local address that is the same family as the peer address. When the connection is established, the PCC and PCE exchange OPEN messages, which initializes the PCEP session and exchanges the session parameters to be negotiated.

By default, the PCC attempts to reach the remote PCE address out of band using the management port. If it cannot, it attempts to reach the remote PCE address in band. The user can change the configuration of the peer to attempt connecting in band only or out of band only. When the session comes up out of band, the management IP address is used as the local address. The local IPv4 address configured by the user is only used for in-band sessions and is otherwise ignored.

The no form of the command removes the configured local address of the PCEP speaker.

Parameters

ip-address

Specifies the IP address of the PCEP speaker to be used for in-band sessions.

Description

This command configures the local IP address used by the group or neighbor when communicating with BGP peers.

Outgoing connections use the local-address as the source of the TCP connection when initiating connections with a peer.

When a local address is not specified, the router uses the system IP address when communicating with IBGP peers and uses the interface address for directly connected EBGP peers. This command is used at the neighbor level to revert to the value defined under the group level.

When set to a router interface, the local-address inherits the primary IPv4 or IPv6 address of the router interface depending on whether BGP is configured for IPv4 or IPv6. If the corresponding IPv4 or IPv6 address is not configured on the router interface, the BGP sessions that have this interface set as the local-address are kept down until an interface address is configured on the router interface.

The no form of this command removes the configured local-address for BGP.

The no form of this command used at the group level returns the configuration to the value defined at the global level.

The no form of this command used at the neighbor level returns the configuration to the value defined at the group level.

Default

Full Context

configure router pcep pce local-address-ipv6

configure router pcep pcc local-address-ipv6

Description

This command configures the local IPv6 address of the PCEP speaker.

The PCEP protocol operates over TCP using destination TCP port 4189. The PCE client (PCC) always initiates the connection. After the user configures the PCEP local IPv6 address and the peer IPv6 address on the PCC, the latter initiates a TCP connection to the PCE. If both a local IPv4 and a local IPv6 address are configured, the connection uses the local address that is the same family as the peer address. When the connection is established, the PCC and PCE exchange OPEN messages, which initializes the PCEP session and exchanges the session parameters to be negotiated.

By default, the PCC attempts to reach the remote PCE address out of band using the management port. If it cannot, it attempts to reach the remote PCE address in-band. The user can change the configuration of the peer to attempt connecting in band only or out of band only. When the session comes up out of band, the management IP address is used as the local address. The local IPv6 address configured by the user is only used for in-band sessions and is otherwise ignored.

The no form of the command removes the configured local address of the PCEP speaker.

Parameters

ipv6-address

Specifies the IP address of the PCEP speaker to be used for in-band sessions.

configure service template vpls-template local-age

Description

Specifies the aging time for locally learned MAC addresses in the forwarding database (FDB) for the Virtual Private LAN Service (VPLS) instance. In a VPLS service, MAC addresses are associated with a Service Access Point (SAP) or with a Service Distribution Point (SDP). MACs associated with a SAP are classified as local MACs, and MACs associated with an SDP are remote MACs.

Like in a Layer 2 switch, learned MACs can be aged out if no packets are sourced from the MAC address for a period of time (the aging time). In each VPLS service instance, there are independent aging timers for local learned MAC and remote learned MAC entries in the FDB. The local-age timer specifies the aging time for local learned MAC addresses.

The no form of this command returns the local aging timer to the default value.

Default

local age 300 — Local MACs aged after 300 seconds.

Parameters

aging-timer

Specifies the aging time for local MACs expressed in seconds

configure subscriber-mgmt bgp-peering-policy local-as

Description

This command configures a BGP virtual autonomous system (AS) number.

In addition to the AS number configured for BGP in the config>router>autonomous-system context, a virtual (local) AS number is configured. The virtual AS number is added to the as-path message before the router’s AS number makes the virtual AS the second AS in the as-path.

This configuration parameter can be set at three levels: global level (applies to all peers), group level (applies to all peers in peer-group) or neighbor level (only applies to specified peer). Thus, by specifying this at each neighbor level, it is possible to have a separate as-number per EBGP session.

When a command is entered multiple times for the same AS, the last command entered is used in the configuration. The private attribute can be added or removed dynamically by reissuing the command.

Changing the local AS at the global level in an active BGP instance causes the BGP instance to restart with the new local AS number. Changing the local AS at the global level in an active BGP instance causes BGP to re-establish the peer relationships with all peers in the group with the new local AS number. Changing the local AS at the neighbor level in an active BGP instance causes BGP to re-establish the peer relationship with the new local AS number.

This is an optional command and can be used in the following circumstance:

Provider router P is moved from AS1 to AS2. The customer router that is connected to P, however, is configured to belong to AS1. To avoid reconfiguring the customer router, the local-as value on router P can be set to AS1. Thus, router P adds AS1 to the as-path message for routes it advertises to the customer router.

The no form of this command used at the global level will remove any virtual AS number configured.

The no form of this command used at the group level reverts to the value defined at the global level.

The no form of this command used at the neighbor level reverts to the value defined at the group level.

Parameters

as-number

Specifies the virtual autonomous system number, expressed as a decimal integer.

Values

1 to 4294967295

private

Specifies that the local-as number is hidden in paths learned from the peering.

Description

This command configures a BGP virtual autonomous system (AS) number.

In addition to the global AS number configured for BGP in the config>router>autonomous-system context, a virtual (local) AS number can be configured to support various AS number migration scenarios. The local AS number is added to the to the beginning the as-path attribute ahead of the router’s AS number.

This configuration parameter can be set at three levels: global level (applies to all EBGP peers), group level (applies to all EBGP peers in peer-group) or neighbor level (only applies to EBGP specified peer). Thus, by specifying this at each neighbor level, it is possible to have a separate local-as per EBGP session. The local-as command is not supported for IBGP sessions. When the optional private keyword is specified in the command the local-as number is not added to inbound routes from the EBGP peer that has local-as in effect.

When a command is entered multiple times for the same AS, the last command entered is used in the configuration. The private attribute can be added or removed dynamically by reissuing the command.

Changing the local AS at the global level in an active BGP instance causes the BGP instance to restart with the new local AS number. Changing the local AS at the global level in an active BGP instance causes BGP to re-establish the peer relationships with all peers in the group with the new local AS number. Changing the local AS at the neighbor level in an active BGP instance causes BGP to re-establish the peer relationship with the new local AS number.

This is an optional command and can be used in the following circumstance:

Provider router P is moved from AS1 to AS2. The customer router that is connected to P, however, is configured to belong to AS1. To avoid reconfiguring the customer router, the local-as value on router P can be set to AS1. Thus, router P adds AS1 to the as-path message for routes it advertises to the customer router.

The no form of this command used at the global level removes any virtual AS number configured.

The no form of this command used at the group level reverts to the value defined at the global level.

The no form of this command used at the neighbor level reverts to the value defined at the group level.

Default

Description

This command configures a BGP local autonomous system (AS) number. In addition to the global AS number configured for BGP using the autonomous-system command, a local AS number can be configured to support various AS number migration scenarios.

When the local-as command is applied to a BGP neighbor and the local-as is different from the peer-as, the session comes up as EBGP and by default the global-AS number and then (in that order) the local-as number are prepended to the AS_PATH attribute in outbound routes sent to the peer. In received routes from the EBGP peer, the local AS is prepended to the AS path by default, but this can be disabled with the private option.

When the local-as command is applied to a BGP neighbor and the local-as is the same as the peer-as, the session comes up as IBGP, and by default, the global-AS number is prepended to the AS_PATH attribute in outbound routes sent to the peer.

This configuration parameter can be set at three levels: global level (applies to all BGP peers), group level (applies to all BGP peers in group) or neighbor level (only applies to one specific BGP neighbor). By specifying this at the neighbor level, it is possible to have a separate local-as for each BGP session.

When the optional no-prepend-global-as command is configured, the global-as number is not added in outbound routes sent to an IBGP or EBGP peer.

When a command is entered multiple times for the same AS, the last command entered is used in the configuration. The private option can be added or removed dynamically by reissuing the command. Changing the local AS at the global level in an active BGP instance causes the BGP instance to restart with the new local AS number. Changing the local AS at the global level in an active BGP instance causes BGP to re-establish the peer relationships with all peers in the group with the new local AS number. Changing the local AS at the neighbor level in an active BGP instance causes BGP to re-establish the peer relationship with the new local AS number.

The no form of this command used at the group level reverts to the value defined at the global level.

The no form of this command used at the neighbor level reverts to the value defined at the group level.

Description

This command configures the local-end address of the following SDP encapsulation types:

  • IPv6 address of the termination point of a SDP of encapsulation l2tpv3 (L2TP v3 tunnel).

  • IPv4/IPv6 source address of a SDP of encapsulation eth-gre-bridged (L2oGRE SDP).

  • IPv4 source address of a SDP of encapsulation gre (GRE SDP).

A change to the value of the local-end parameter requires that the SDP be shut down.

When used as the source address of a SDP of encapsulation gre (GRE SDP), the primary IPv4 address of any local network IP interface, loopback or otherwise, may be used.

The address of the following interfaces are not supported:

  • unnumbered network IP interface

  • IES interface

  • VPRN interface

  • CSC VPRN interface

The local-end parameter value adheres to the following rules:

  • A maximum of 15 distinct address values can be configured for all GRE SDPs under the config>service>sdp>local-end context, and all L2oGRE SDPs under the config>service>system>gre-eth-bridged>tunnel-termination context.

  • The same source address cannot be used in both contexts since an address configured for a L2oGRE SDP matches an internally created interface that is not available to other applications.

  • The local-end address of a GRE SDP, when different from system, need not match the primary address of an interface that has the MPLS-over-GRE termination subnet configured, unless a GRE SDP or tunnel from the far-end router terminates on this address.

The no form of the command removes the address from the local-end configuration.

Parameters

ip-address | ipv6-address

Specifies a IPv4 or IPv6 address for local-end of an SDP in dotted decimal notation.

Description

This command configures the local (from the VPN) IP prefix/mask for the policy parameter entry.

Only one entry is necessary to describe a potential flow. The local-ip and remote-ip commands can be defined only once. The system evaluates:

  • the local IP as the source IP when traffic is examined in the direction of the flows from private to public and as the destination IP when traffic flows from public to private

  • the remote IP as the source IP when traffic flows public to private and as the destination IP when traffic flows from private to public

Parameters

ip-prefix

The destination address of the aggregate route in dotted decimal notation

Values

a.b.c.d (host bits must be 0)

prefix-length 1 to 32

netmask

configure router ldp interface-parameters interface ipv6 local-lsr-id

configure router ldp interface-parameters interface ipv4 local-lsr-id

Description

This command enables the use of the address of the local LDP interface, or any other network interface configured on the system, as the LSR-ID to establish link LDP Hello adjacency and LDP session with directly connected LDP peers. The network interface can be a loopback or not.

Link LDP sessions to all peers discovered over a given LDP interface share the same local LSR-ID. However, LDP sessions on different LDP interfaces can use different network interface addresses as their local LSR-ID.

By default, the LDP session to a peer uses the system interface address as the LSR-ID unless explicitly configured using this command. The system interface must always be configured on the router, or the LDP protocol will not come up on the node. There is no requirement to include the system interface in any routing protocol.

At initial configuration, the LDP session to a peer will remain down while the network interface used as LSR-ID is down. LDP will not try to bring it up using the system interface.

If the network IP interface used as LSR-ID goes down, the LDP sessions to all discovered peers using this LSR-ID go down.

When an interface other than the system is used as the LSR-ID, the transport connection (TCP) for the link LDP session will also use the address of that interface as the transport address. If the system or interface value is configured in the config>router>ldp>if-params>if>ipv4 or config>router>ldp>if-params>if>ipv6> transport-address context, it will be overridden with the address of the LSR-ID interface.

When the local-lsr-id command is enabled with the 32bit-format option, an SR OS LSR will be able to establish an LDP IPv6 Hello adjacency and an LDP IPv6 session with an RFC 7552 compliant peer LSR. The LSR uses a 32-bit LSR-ID set to the value of the IPv4 address of the specified local LSR-ID interface and a 128-bit transport address set to the value of the IPv6 address of the specified local LSR-ID interface.

Note:

The system interface cannot be used as a local LSR-ID with the 32bit-format option enabled because the system interface is the default LSR-ID and transport address for all LDP sessions to peers on this LSR. This configuration is blocked in the CLI.

If the user enables the 32bit-format option in the IPv6 context of a running LDP interface, the already established LDP IPv6 Hello adjacency and LDP IPv6 session will be brought down and re-established with the new 32-bit LSR-ID value.

If the user changes the LSR-ID value between system, interface, and interface-name, or enables the 32bit-format option while the LDP session is up, LDP will immediately tear down all sessions using this LSR-ID and will attempt to re-establish them using the new LSR-ID.

The no form of this command returns to the default behavior, in which case the system interface address is used as the LSR-ID.

Default

no local-lsr-id

Parameters

system

Specifies the use of the address of the system interface as the value of the LSR-ID of this LDP LSR.

interface

Specifies the use of the address of the local LDP interface as the value of the LSR-ID of this LDP LSR.

interface-name interface-name

Specifies the name, up to 32 character, of the network IP interface (which address is used as the LSR-ID of this LDP LSP). An interface name cannot be in the form of an IP address. If the string contains special characters (#, $, spaces, and so on), the entire string must be enclosed within double quotes.

configure router ldp targeted-session peer local-lsr-id

Description

This command enables the use of the address of any network interface configured on the system, as the LSR-ID to establish a targeted LDP Hello adjacency and a targeted LDP session with an LDP peer. The network interface can be a loopback or not.

By default, the targeted LDP session to a peer uses the system interface address as the LSR-ID and as the transport address, unless explicitly configured using this command. The system interface must always be configured on the router, or the LDP protocol will not come up on the node. There is no requirement to include the system interface in any routing protocol.

When the local-lsr-id command is enabled with the 32bit-format option, an SR OS LSR will be able to establish a targeted LDP IPv6 Hello adjacency and a targeted LDP IPv6 session with an RFC 7552 compliant peer LSR. The LSR uses a 32-bit LSR-ID set to the value of the IPv4 address of the specified local LSR-ID interface and a 128-bit transport address set to the value of the IPv6 address of the specified local LSR-ID interface.

Note:

The system interface cannot be used as a local LSR-ID with the 32bit-format option enabled because the system interface is the default LSR-ID and transport address for all targeted LDP sessions to peers on this LSR. This configuration is blocked in the CLI.

If the user enables the 32bit-format option in the IPv6 context of a running targeted LDP peer, the already established targeted LDP IPv6 Hello adjacency and targeted LDP IPv6 session will be brought down and re-established with the new 32-bit LSR-ID value.

If the user changes the local LSR-ID value or enables/disables the 32bit-format option, while the targeted LDP session is up, LDP will immediately tear down the targeted session using this LSR-ID and will attempt to re-establish it using the new LSR-ID.

The no form of this command returns to the default behavior, in which case the system interface address is used as the LSR-ID.

Default

no local-lsr-id

Parameters

configure system security dist-cpu-protection policy local-monitoring-policer

Description

This command configures a monitoring policer that is used to monitor the aggregate rate of several protocols arriving on an object (for example, SAP). When the local-monitoring-policer is determined to be in a nonconforming state (at the end of a minimum monitoring time of 60 seconds) then the system will attempt to allocate dynamic policers for the particular object for any protocols associated with the local monitor (for example, using the protocol name enforcement dynamic policer-name CLI command).

If the system cannot allocate all the dynamic policers within 150 seconds, it will stop attempting to allocate dynamic policers, raise a LocMonExcdAllDynAlloc log event, and go back to using the local monitor. The local monitor may then detect exceeded packets again and make another attempt at allocating dynamic policers.

Once this policer-name is referenced by a protocol then this policer will be instantiated for each "object” that is created and references this DDoS policy. If there is no policer free then the object will be blocked from being created.

configure service vprn local-routes-domain-id

Description

This command specifies the domain ID that is used in the D-PATH attribute for local routes before those routes are exported to a BGP neighbor using BGP-IPVPN, EVPN-IFF, EVPN-IFL or PE-CE BGP. A local route is a non-BGP route installed in the VPRN route table and learned using static route or an IGP.

The domain IDs are used in the D-PATH attribute, in accordance with draft-ietf-bess-evpn-ipvpn-interworking. The D-PATH attribute is modified by gateway routers, where a gateway is defined as a PE where a VPRN is instantiated, and that VPRN advertises or receives routes from multiple BGP owners (for example, EVPN-IFL and BGP-IPVPN).

The D-PATH attribute is used on gateways to detect loops (for received routes where the D-PATH contains a local domain ID) and to make BGP best path selection decisions based on the D-PATH length (shorter D-PATH is preferred).

The no form of this command removes the domain ID for local routes.

Default

Description

This command configures the SR LFA protection needed for the adjacencies used in the path computation of an SR-TE LSP by the local CSPF.

The default value of the command is preferred. The local CSPF will prefer a protected adjacency over an unprotected adjacency whenever both exist for a TE link. However, the entire computed path can combine both types of adjacencies.

When the user enables the mandatory value, CSPF uses it as an additional path constraint and selects protected adjacencies exclusively in computing the path of the SR-TE LSP. CSPF will return no path if all candidate paths that otherwise satisfy all other LSP path constraints do not have an unprotected SID for each of their TE links.

Similarly, if the user enables the value none, CSPF uses it as an additional path constraint and selects unprotected adjacencies exclusively in computing the path of the SR-TE LSP. CSPF will return no path if all candidate paths that otherwise satisfy all other LSP path constraints do not have a protected SID for each of their TE links.

The no form of this command returns the command to its default value.

Default

no local-sr-protection

Parameters

local-sr-protection

Specifies the local-sr-protection for LSPs.

Values

none — Selects unprotected adjacencies only in the SR-TE LSP path computation.

preferred — Prefers protected adjacencies in the SR-TE LSP path computation.

mandatory — Selects protected adjacencies only in the SR-TE LSP path computation.

Description

This command instructs the system where to write the persistency files for the corresponding application. Each application creates two files on the flash card, one with suffix .i<version>, referencing an index file, and the other with suffix .0<version>, where <version> is a 2-digit number reflecting the file version. These versions are not related to the SR OS release running on the node. The <version> can remain the same over two major releases, for example, when no format change is made to the persistency file. On boot, the system scans the file systems looking for the corresponding persistency files, and the load begins.

For example, in the subscriber management context, the location specifies the flash device on a CPM card where the data for handling subscriber management persistency is stored.

The no form of this command returns the system to the default. If there is a change in file location while persistence is running, a new file will be written on the new flash, and then the old file will be removed.

Description

This command configures the remote location where the Python script will be exported. The Python script is then used off-line to perform reverse query. If this command is configured, the Python script generation is triggered by any modification of the deterministic NAT configuration. The new script reflects the change in mappings caused by configuration change. However, the script must be manually exported to the outside location with the admin nat save-deterministic-nat command. The script cannot be stored locally on the system.

The script allows two forms of queries:

  • Forward – input is NAT inside parameters, output is NAT outside parameters.

  • Backward – input is NAT outside parameters, output is NAT inside parameters.

Forward Query:

user@external-server:/home/ftp/pub/det-nat-script$ ./det-nat.py -f -s 10 -a 10.0.5.10 

output:

subscriber has public ip address 198.51.100.1 from service 0 and is using ports [1324 - 1353]

Reverse Query:

user@external-server:/home/ftp/pub/det-nat-script$./det-nat.py -b -s 0 -a 198.51.100.1 -p 3020

output:

subscriber has private ip address 10.0.5.66 from service 10

Default

configure log file file-id location

Description

This command specifies the primary and optional backup location where the log or billing file will be created.

The location command is optional. If the location command not explicitly configured, log files will be created on cf1: and accounting files will be created on cf2: without overflow onto other devices. Generally, cf3: is reserved for system files (configurations, images, and so on).

When multiple location commands are entered in a single file ID context, the last command overwrites the previous command.

When the location of a file ID that is associated with an active log ID is changed, the log events are not immediately written to the new location. The new location does not take effect until the log is rolled over either because the rollover period has expired or a clear log log-id command is entered to manually rollover the log file.

When creating files, the primary location is used as long as there is available space. If no space is available, an attempt is made to delete unnecessary files that are past their retention date.

If sufficient space is not available an attempt is made to remove the oldest to newest closed log or accounting files. After each file is deleted, the system attempts to create the new file.

A medium severity trap is issued to indicate that a compact flash is either not available or that no space is available on the specified flash and that the backup location is being used.

A high priority alarm condition is raised if none of the configured compact flash devices for this file ID are present or if there is insufficient space available. If space does becomes available, then the alarm condition will be cleared.

Log files are created on cf1: and accounting files are created on cf2.

Use the no form of this command to revert to default settings.

Full Context

configure ipsec ike-policy lockout

Description

This command enables the lockout mechanism for the IPsec tunnel. The system will lock out an IPsec client for the configured time interval if the number of failed authentications exceeds the configured value within the specified duration. This command only applies when the system acts as a tunnel responder.

A client is defined as the tunnel IP address plus the port.

Optionally, the max-port-per-ip parameter can be configured as the maximum number of ports allowed behind the same IP address. If this threshold is exceeded, then all ports behind the IP address are blocked.

The no form of this command disables the lockout mechanism.

Default

no lockout

[Tree] (config>system>ptp log-anno-interval)

Full Context

configure system ptp log-anno-interval

Description

This command configures the announce message interval used for both unicast and multicast messages.

For unicast messages, it defines the announce message interval that is requested during unicast negotiation to any peer. This controls the announce message rate sent from remote peers to the local node. It does not affect the announce message rate that may be sent from the local node to remote peers. Remote peers may request an announce message rate anywhere within the acceptable grant range.

For multicast messages, used on PTP Ethernet ports, this configures the message interval used for Announce messages transmitted by the local node.

This value also defines the interval between executions of the BMCA within the node.

The announce-interval cannot be changed unless the PTP is shut down.

Note:

In order to minimize BMCA driven reconfigurations, the IEEE recommends that the announce-interval should be consistent across the entire 1588 network.

The no form of this command reverts the configuration to the default value. The default value varies depending on the configuration of the profile command.

Default

log-anno-interval 1 (1 packet every 2 seconds) for ieee1588-2008

log-anno-interval 1 (1 packet every 2 seconds) for g8265dot1-2010

log-anno-interval -3 (8 packets per second) for g8275dot1-2014

Full Context

configure system ptp port log-delay-interval

Description

This command configures the minimum interval used for multicast Delay_Req messages. This parameter is applied on a per-port basis. For ports in a timeReceiver state, it shall be the interval used, unless the parent port indicates a longer interval. For a port in timeTransmitter state, it shall be the interval advertised to external timeReceiver ports as the minimum acceptable interval for Delay_Req messages from those timeReceiver ports.

It is a requirement of the 1588 standard that a port in timeReceiver state shall check the logMessageInterval field of received multicast Delay_Resp messages. If the value of the logMessageInterval field of those messages is greater than the value programmed locally for the generation of Delay_Req messages, then the timeReceiver must change to use the greater value (i.e. longer interval) for the generation of Delay_Req messages. This requirement is supported in the router.

The parameter is only applicable to ports and not to peers.

The no form of this command reverts the configuration to the default value. The default value varies depending on the configuration of the profile command.

Default

log-delay-interval -6 (64 packets per second) for ieee1588-2008

log-delay-interval -6 (64 packets per second) for g8265dot1-2010

log-delay-interval -4 (16 packets per second) for g8275dot1-2014

Description

This command configures the limit for the total space that all log files can occupy on each storage device on the active CPM.

When this threshold is reached, log events are no longer written to the files in the \log directory until SR OS removes older log files and the occupancy is below the limit.

When unconfigured, there is no specific limit for the total size of all log files.

Only log files in the \log directory with system generated names (including no file extension) are applicable toward the total size limit.

If a user manually adds or deletes log files from the \log directory, the size of the files is not taken into account for up to 1 hour.

The configured total size limit is not validated against the actual size of the installed storage devices. If the configured limit is larger than the installed CF device, the limit is never reached.

Default

no log-files-total-size

Description

This command configures the log filter to be used for this trigger entry. The log filter defines the matching criteria that must be met in order for the log event to trigger the handler execution. The log filter is applied to the log event and, if the filtering decision results in a forward action, then the handler is triggered.

It is typically unnecessary to configure match criteria for the application or number in the log filter used for EHS since the particular filter is only applied for a specific log event application and number, as configured under the config>log>event-trigger context.

Description

This command creates a context to configure destinations for event streams.

The log-id context is used to direct events, alarms or traps, and debug information to respective destinations.

A maximum of 30 logs can be configured.

Before an event can be associated with this log-id, the from command identifying the source of the event must be configured.

Only one destination can be specified for a log-id. The destination of an event stream can be an in-memory buffer, console, session, snmp-trap-group, Syslog, or file.

Use the event-control command to suppress the generation of events, alarms, and traps for all log destinations.

An event filter policy can be applied in the log-id context to limit which events, alarms, and traps are sent to the specified log-id.

By default, the log events in a VPRN log are a subset of the complete set of possible log events in SR OS. See the config>log>services-all-events command for more details.

The no form of this command deletes the log destination ID from the configuration.

Default

Description

This command provides additional control over the behavior enabled by the loop-detect command. If this command specifies a threshold value of n, then a route received by the local BGP speaker with an AS path that contains up to n occurrences of the local speaker's AS number is considered valid and not treated as an AS path loop. An AS loop is considered to occur only when the received AS path has more than n occurrences of the local speaker's AS number.

The no form of this command removes the configuration and sets the value to 0. One or more occurrence of the local speaker's AS number in the received AS path triggers the loop-detect behavior.

Default

no loop-detect-threshold

Parameters

loop-detect-threshold

The maximum number of occurrences of the local speaker's AS number in the received AS path before the AS path is considered to be a loop.

The implementation also allows the user to exclude a specific interface in IS-IS or OSPF, a or all interfaces in an OSPF area or IS-IS level from the LFA SPF.

Note:

Prefix tags are defined for the IS-IS protocol but not for the OSPF protocol.

The default action of the loopfree-alternate-exclude command, when not explicitly specified by the user in the prefix policy, is "reject”. Therefore, regardless of whether the user explicitly added the statement "default-action reject” to the prefix policy, a prefix that does not match any entry in the policy will be accepted into LFA SPF.

The no form of this command deletes the exclude prefix policy.

Default

no loopfree-alternate-exclude

Parameters

prefix-policy

Specifies up to five policy prefix names. The specified policy name must already be defined. Prefix policies are created with the command config>router>policy-options>prefix-list; for information on prefix lists, refer to "Route Policies” in the 7450 ESS, 7750 SR, 7950 XRS, and VSR Unicast Routing Protocols Guide.

Description

This command instructs IGP to not include a specific interface or all interfaces participating in a specific IS-IS level or OSPF area in the SPF LFA computation. This provides a way of reducing the LFA SPF calculation where it is not needed.

When an interface is excluded from the LFA SPF in IS-IS, it is excluded in both level 1 and level 2. When it is excluded from the LFA SPF in OSPF, it is excluded in all areas. However, the above OSPF command can only be executed under the area in which the specified interface is primary and once enabled, the interface is excluded in that area and in all other areas where the interface is secondary. If the user attempts to apply it to an area where the interface is secondary, the command will fail.

The no form of this command re-instates the default value for this command.

Description

This command enables Loop-Free Alternate (LFA) computation by SPF for the IS-IS routing protocol.

When this command is enabled, it instructs the IGP SPF to attempt to pre-compute both a primary nexthop and an LFA next-hop for every learned prefix. When found, the LFA next-hop is populated into the routing table along with the primary next-hop for the prefix.

The user enables the remote LFA next-hop calculation by the IGP LFA SPF by appending the remote-lfa option. When this option is enabled in an IGP instance, SPF performs the remote LFA additional computation following the regular LFA next-hop calculation when the latter resulted in no protection for one or more prefixes which are resolved to a given interface.

Remote LFA extends the protection coverage of LFA-FRR to any topology by automatically computing and establishing/tearing-down shortcut tunnels, also referred to as repair tunnels, to a remote LFA node which puts the packets back into the shortest without looping them back to the node which forwarded them over the repair tunnel. The remote LFA node is referred to as PQ node. A repair tunnel can in theory be an RSVP LSP, a LDP-in-LDP tunnel, or a SR tunnel. In this feature, it is restricted to use SR repair tunnel to the remote LFA node.

The remote LFA algorithm is a per-link LFA SPF calculation and not a per-prefix like the regular LFA one. So, it provides protection for all destination prefixes which share the protected link by using the neighbor on the other side of the protected link as a proxy for all these destinations.

The Topology-Independent LFA (TI-LFA) further improves the protection coverage of a network topology by computing and automatically instantiating a repair tunnel to a Q node which is not in shortest path from the computing node. The repair tunnel uses shortest path to the P node and a source routed path from the P node to the Q node.

In addition, the TI-LFA algorithm selects the backup path which matches the post-convergence path. This helps the capacity planning in the network since traffic will always flow on the same path when transitioning to the FRR next-hop and then onto the new primary next-hop.

At a high level, the TI-LFA protection algorithm is searching for a candidate P-Q set separated with a number of hops such that the label stack size does not exceed the value of ti-lfa max-sr-frr-labels, on each of the post-convergence paths to each destination node or prefix D.

When the ti-lfa option is enabled in IS-IS, it provides TI-LFA node-protect or link-protect backup path in IS-IS MT=0 for an SR-ISIS IPV4/IPv6 tunnel (node SID and adjacency SID), for an IPv4 SR-TE LSP, and for LDP IPv4 FEC when the LDP fast-reroute backup-sr-tunnel option is enabled.

The max-sr-frr-labels parameter is used to limit the search for the TI-LFA backup next-hop:

  1. 0 — The IGP LFA SPF restricts the search to TI-LFA backup next-hop which does not require a repair tunnel, meaning that P node and Q node are the same and match a neighbor. This is also the case when both P and Q node match the advertising router for a prefix.

  2. 1 to 3 — The IGP LFA SPF will widen the search to include a repair tunnel to a P node which itself is connected to the Q nodes with a 0-to-2 hops for a total of maximum of three labels: one node SID to P node and two adjacency SIDs from P node to the Q node. If the P node is a neighbor of the computing node, its node SID is compressed and meaning that up to three adjacency SIDs can separate the P and Q nodes.

  3. 2 (default) — Corresponds to a repair tunnel to a non-adjacent P which is adjacent to the Q node. If the P node is a neighbor of the computing node, then the node SID of the P node is compressed and the default value of two labels corresponds to two adjacency SIDs between the P and Q nodes.

When the node-protect command is enabled, the router will prefer a node-protect over a link-protect repair tunnel for a given prefix if both are found in the Remote LFA or TI-LFA SPF computations. The SPF computations may only find a link-protect repair tunnel for prefixes owned by the protected node. This node-protect backup protects against the failure of a downstream node in the path of the prefix of a node SID except for the node owner of the node SID.

The parameter max-pq-nodes in Remote LFA controls the maximum number of PQ nodes found in the LFA SPFs for which the node protection check is performed. The node-protect condition means the router must run the original Remote LFA algorithm plus one extra forward SPF on behalf of each PQ node found, potentially after applying the max-pq-cost parameter, to check if the path from the PQ node to the destination does not traverse the protected node. Setting this parameter to a lower value means the LFA SPFs will use less computation time and resources but may result in not finding a node-protect repair tunnel.

The no form of this command disables the LFA computation by IGP SPF.

This command enables Loop-Free Alternate (LFA) computation by SPF under the OSPF or OSPFv3 routing protocol instance.

When this command is enabled, it instructs the IGP SPF to attempt to precalculate both a primary next hop and an LFA next hop for every learned prefix. When found, the LFA next hop is populated into the routing table along with the primary next hop for the prefix.

The user enables the remote LFA next hop calculation by the IGP LFA SPF by appending the remote-lfa option. When this option is enabled in an IGP instance, SPF performs the remote LFA additional computation following the regular LFA next hop calculation when the latter resulted in no protection for one or more prefixes which are resolved to a particular interface.

Remote LFA extends the protection coverage of LFA-FRR to any topology by automatically computing and establishing or tearing down shortcut tunnels, also referred to as repair tunnels, to a remote LFA node that puts the packets back into the shortest path without looping them back to the node that forwarded them over the repair tunnel. The remote LFA node is referred to as a PQ node. A repair tunnel can, in theory, be an RSVP-TE LSP, an LDP-in-LDP tunnel, or a segment routing (SR) tunnel. In this command, remote-lfa is restricted to using an SR repair tunnel to the remote LFA node.

When the ti-lfa option is enabled in OSPF, it provides TI-LFA node-protect or link-protect backup path for a SR-OSPF IPV4 tunnel (node SID and adjacency SID), and for a IPv4 SR-TE LSP.

The max-sr-frr-labels parameter is used to limit the search for the TI-LFA backup next hop:

  1. 0 — The IGP LFA SPF restricts the search to TI-LFA backup next hop which does not require a repair tunnel, meaning that P node and Q node are the same and match a neighbor. This is also the case when both P and Q node match the advertising router for a prefix.

  3. 2 (default) — Corresponds to a repair tunnel to a non-adjacent P which is adjacent to the Q node. If the P node is a neighbor of the computing node, then the node SID of the P node is compressed and the default value of two labels corresponds to two adjacency SIDs between the P and Q nodes.

The TI-LFA repair tunnel can have a maximum of three labels pushed in addition to the label of the destination node or prefix. The user can set a lower maximum value for the additional FRR labels by configuring the CLI option max-sr-frr-labels labels. The default value is 2.

When the node-protect command is enabled, the router will prefer a node-protect over a link-protect repair tunnel for a given prefix if both are found in the Remote LFA or TI-LFA SPF computations. The SPF computations may only find a link-protect repair tunnel for prefixes owned by the protected node.

configure port ethernet egress hs-secondary-shaper aggregate low-burst-max-class

Description

This command specifies which scheduling classes map to the low burst-limit threshold of an egress HS secondary shaper. Egress SAPs can be configured to use an HS secondary shaper that manages their maximum burst limit over a specified aggregate shaping rate. Each HS secondary shaper supports two thresholds, a low burst limit threshold and a high burst limit threshold.

By default, all scheduling classes are mapped to the low burst limit threshold. It is important to note that when mapping scheduling classes to the high burst limit threshold an adequate value for the card>fp>egress>hs-fixed-high-thresh-delta must be specified. This is due to the fact that the queues associated with the lower classes may burst over the lower threshold in normal operation due to the scheduler forwarding whole packets. The hs-fixed-high-thresh-delta value should be set to at least two times the maximum frame size to prevent lower threshold class forwarding from also affecting the higher threshold classes when forwarding larger packet sizes. An insufficient high threshold delta defeats the intended purpose of mapping classes to the higher threshold.

The system utilizes the lowest value attainable for each low threshold aggregate burst limit without causing shaper underrun conditions. The high burst limit threshold is determined by adding the hs-fixed-high-thresh-delta value configured in the config>card>fp>egress context to the aggregate’s low burst limit threshold value.

The low-burst-max-class value can be changed at any time for an HS secondary shaper.

The no form of this command restores the HS secondary shaper’s aggregate low burst limit threshold maximum scheduling class mapping to the default value. This causes all sets of queues associated with the hs-secondary-shaper secondary-shaper-name to have all scheduling classes mapped to the low burst limit threshold.

Default

low-burst-max-class 6

Parameters

class

Specifies the low burst maximum class. This parameter is required when executing the low-burst-max-class command. The parameter reflects the highest scheduling class that will be associated with the low burst limit threshold associated with the HS secondary aggregate shaper. Scheduling classes higher than scheduling class ID will be associated with the high burst limit threshold.

configure qos hs-attachment-policy low-burst-max-class

Description

This command specifies which scheduling classes map to the low burst-limit threshold of the queue-level aggregate shaper. Each egress SAP or subscriber SLA profile instance (SPI), per port set of network interface queues and egress queue group template instance has an aggregate shaper that manages the maximum burst limit over a specified shaping rate. Each aggregate shaper supports two thresholds. As the scheduling rate for the set of queues increases, eventually the aggregate rate exceeds the rate limit and the aggregate burst limit starts to be consumed. If this continues, the low burst limit threshold is exceeded and the queues mapped to the scheduling classes associated with low threshold are removed from the scheduler. If the remaining aggregate rate (from the higher scheduling classes) continues to exceed the shaping rate, then the burst limit continues to be consumed and eventually the high burst limit threshold is exceeded. This causes the queues for all scheduling classes to be removed from the scheduler.

The second (high) threshold exists to allow the higher priority classes to continue to forward, thereby mitigating the effects of low priority bursts beyond the aggregate shaping rate. Typically, the higher scheduling class queues are either individually rate-limited so their aggregate allowed throughput is less than the aggregate rate or the expected aggregate unshaped traffic from the individual higher scheduling classes does not exceed the aggregate shaping rate. Determining the value of low-burst-max-class class involves anticipating the proper dividing line between the low and high scheduling classes by evaluating the forwarding behavior and SLA enforcement of each class.

By default, all scheduling classes are mapped to the low burst limit threshold. When mapping scheduling classes to the high burst limit threshold, an adequate value for the card>fp>egress>hs-fixed-high-thresh-delta must be specified. This is due to the fact that the queues associated with the lower classes may burst over the lower threshold in normal operation due to the scheduler forwarding whole packets. Set the hs-fixed-highthresh- delta value to at least two times the maximum frame size to prevent lower threshold class forwarding from also affecting the higher threshold classes when forwarding larger packet sizes. An insufficient high threshold delta defeats the intended purpose of mapping classes to the higher threshold.

The system utilizes the lowest value attainable for each low threshold aggregate burst limit without causing shaper underrun conditions. The high burst limit threshold is determined by adding the hs-fixed-high-thresh-delta value configured in the config>card>fp>egress CLI context to the aggregate’s low burst limit threshold value.

The low-burst-max-class value can be changed at any time in the HS attachment policy. Modifying the setting causes all queue aggregate shapers to reconfigure the scheduling class mappings to the low and high burst limit thresholds to reflect the new value for scheduling class ID.

Scheduling Classes — As described in the queue and wrr-group attachment commands, each queue is either directly or indirectly (through a WRR group) mapped to a scheduling class. Each scheduling class has an inherent priority at the port scheduler. The inherent descending priority is as follows:

  • Scheduling Class 6 (Highest)

  • Scheduling Class 5

  • Scheduling Class 4

  • Scheduling Class 3

  • Scheduling Class 2

  • Scheduling Class 1 (lowest)

Placing scheduling classes into the port level WRR group causes those classes to compete for scheduling opportunities based on their associated weights instead of inherent priority. If higher weights are given to higher scheduling class IDs, then the relative proportional scheduling priority may continue to exhibit the priority level indicated by the class ID.

Setting Low and High Burst Limit Threshold Association — Low and High Burst Limit Threshold Association demonstrates the effect of the low-burst-max-class command parameters on scheduling class mappings to the low and high burst limit thresholds.

The no form of the command restores the queue aggregate low burst limit threshold maximum scheduling class mapping to the default value. This causes all sets of queues associated with the specified hs-attachment-policy policy-name to have all scheduling classes mapped to the low burst limit threshold.

Default

low-burst-max-class 6

Parameters

class

Specifies the low burst maximum class. This parameter is required when executing the low-burst max-class command. The parameter reflects the highest scheduling class that is associated with the low burst limit threshold associated with the queue aggregate shaper. Scheduling classes higher than the scheduling class ID are associated with the high burst limit threshold.

Description

This command allows the operator specify the individual floors thresholds for the bins. The operator does not have to specific a lower threshold for every bin that was previously defined by the bin-count for the specific type. By default, each bin is the bin-number times 5000 microseconds. Lower thresholds in the previous adjacent bin must be lower than the threshold of the next higher bin threshold. A separate line per bin is required to configure an operator-specific threshold. An error prevents the bin from entering the active state if this is not maintained, at the time the no shutdown is issued. Bin 0 is the result of the difference between 0 and the configured lower-threshold of bin 1. The highest bin in the bin-count captures every result above the threshold. Any negative delay metric result is treated as zero and placed in bin 0.

The no form of this command removes the user configured threshold value and applies the default for the bin.

Parameters

microseconds

Specifies the threshold that defines the floor of the bin. The bin range is the difference between its configured threshold and the threshold of the next higher bin in microsecond threshold value.

Description

This command sets the internal OSPF delay to allow for the accumulation of multiple LSA so OSPF messages can be sent as efficiently as possible. The lsa-accumulate timer applies to all LSAs except Type 1 and Type 2 LSAs, which are sent immediately. LSAs are accumulated and then sent when:

  • its size reaches the MTU size of the interface

  • a new LSA is received on the interface

  • the lsa-accumulate timer expires

Shorting this delay can speed up the advertisement of LSAs to OSPF neighbors but may increase the number of OSPF messages sent.

The no form of this command reverts to the default value.

Note:

The timer granularity is 10 ms if the value is less than 500 ms, and 100 ms if the value is greater than or equal to 500 ms. Timer values are rounded down to the nearest granularity, for example a configured value of 550 ms is internally rounded down to 500 ms.

Description

This command enables filtering of outgoing OSPF LSAs on the selected OSPFv2 or OSPFv3 interface. Three filtering options are provided:

  • Do not flood any LSAs out the interface. This option is suitable if the neighbor is simply-connected and has a statically configured default route with the address of this interface as next-hop.

  • Flood the router’s own router-LSA out the interface and suppress all other flooded LSAs. This option is suitable if the neighbor is simply-connected and has a statically configured default route with a loopback or system interface address (contained in the router-LSA) as next-hop.

  • Flood the router’s own router-LSA and all self-generated type-3, type-5 and type-7 LSAs advertising a default route (0/0) out the interface; suppress all other flooded LSAs. This option is suitable if the neighbor is simply-connected and does not have a statically configured default route.

The no form of this command disables OSPF LSA filtering (normal operation).

Description

This parameter customizes the throttling of OSPF LSA-generation. Timers that determine when to generate the first, second, and subsequent LSAs can be controlled with this command. Subsequent LSAs are generated at increasing intervals of the lsa-second-wait timer until a maximum value is reached.

Configuring the lsa-arrival interval to equal or less than the lsa-second-wait interval configured in the lsa-generate command is recommended.

The no form of this command reverts to the default.

Note:

The timer granularity is 10 ms if the value is less than 500 ms, and 100 ms if the value is ≥ 500 ms. Timer values are rounded down to the nearest granularity, for example a configured value of 550 ms is internally rounded down to 500 ms.

Parameters

max-lsa-wait

Specifies the maximum interval, in milliseconds, between two consecutive occurrences of an LSA being generated.

Values

10 to 600000

Default

5000

lsa-initial-wait

Specifies the first waiting period between link-state advertisements (LSA) originate(s), in milliseconds. When the LSA exceeds the lsa-initial-wait timer value and the topology changes, there is no wait period and the LSA is immediately generated.

When an LSA is generated, the initial wait period commences. If, within the specified lsa-initial-wait period and another topology change occurs, then the lsa-initial-wait timer applies.

Values

10 to 600000

Default

5000

lsa-second-wait

Specifies the hold time in milliseconds between the first and second LSA generation. The next topology change is subject to this second wait period. With each subsequent topology change, the wait time doubles (this is 2x the previous wait time). This assumes that each failure occurs within the relevant wait period.

Context

[Tree] (config>service>nat>fwd lsn)

Full Context

configure service nat port-forwarding lsn

Description

This command creates NAT static port forwards for LSN44, Ds-Lite and NAT64. Static port forwards (SPF) are static mappings created so that certain applications on the inside (private side) can be reached from host that are on the outside of the NAT. SPF statically map the subscriber (inside IP address in LSN44, CPE IPv6 address/prefix in DS-Lite and IPv6 prefix in NAT64), inside port and protocol to an outside IPv4 address, port and the same protocol.

If only the inside router, the inside IPv4/v6 address/prefix and the protocol are configured as parameters in the SPF request, the remaining fields in the mapping (outside port and outside IPv4 address) will be selected automatically by the node and reported in CLI once the command execution is completed.

Specifying the outside IPv4 address in the SPF request, mandates that all other, otherwise optional, parameters be also specified in the request (inside port and outside port). This creates a fully specified SPF request. Fully specified SPF request can be used in multi-chassis NAT redundancy deployments where the SPF is manually replicated between the SR OS nodes. In single chassis NAT deployments, fully specified SPF request is guaranteed to work only in the system with a single MS-ISA in it. Otherwise (multiple MS-ISAs in the system) a conflict may arise where two distinct inside IP addresses that may reside on separate MS-ISAs are requested to be mapped to the same outside IPv4 address. This will not be possible since the outside IPv4 address cannot be split across the MS-ISAs (each IP address, inside or outside, is tied to a single MS-ISA).

In non-fully specified SPF requests (missing the inside port and/or outside port and the outside IPv4 address within the SPF request), the outside IPv4 address selection will depend on the configuration of the outside port in the SPF request:

  • If the outside port is not specified or is specified from the configured port-forwarding-range [1024..port-forwarding-range], then the outside IPv4 address will be the same as the outside IPv4 address in an existing dynamic mapping for the same subscriber. If the subscriber does not exist (no dynamic mappings exist at the time of SPF creation request), then the subscriber will be automatically created and an outside IPv4 address will be assigned. In case that the outside ports are not available from the outside IPv4 address of the corresponding dynamic mapping, then the SPF request will fail. In other words, the dynamic and static mappings (created in this manner) for the same subscriber must use the same outside IPv4 address.

  • If the outside port from the well-known port range [0 to 1023] is requested, then the outside IPv4 address does not have to match the outside IPv4 address of an existing dynamic mapping for the same subscriber, but can instead be any outside IPv4 address.

If multiple NAT policies per inside routing context are used, then the NAT policy must be specified in the SPF creation request. This is needed so the SPF be created in the correct pool.

SPFs are disabled by default and they must be explicitly enabled by the port-limits forwarding command within the NAT policy.

Configured SPFs, unlike SPFs created with the tools commands, are preserved across reboots without having to configure persistency (config>system>persistence>nat-port-forwarding) since they are part of the configuration. When the pool is shutdown the SPFs are deactivated. When the pool is enabled (no shutdown), the SPFs (as created by the tools command or by configuration) are activated.

To avoid possible persistency related conflicts, SPFs can only be created using one method on a given node: either as configuration (the CLI configure branch) or using the tools command. For example: if a first SPF entry is created via CLI tools commands, the node prevents SPF creation via configuration (the CLI configure branch) and vice versa.

The no form of the command deletes NAT static port forwards for LSN44, Ds-Lite and NAT64.

configure router mpls ingress-statistics lsp

Description

This command configures statistics in the ingress data path of a terminating RSVP LSP at an egress LER. The LSP name must correspond to the name configured by the operator at the ingress LER. It must not contain the special character ":” which is used as a field separator by the ingress LER for encoding the LSP and path names into the RSVP session name field in the session_attribute object. The operator must execute the no shutdown for this command to effectively enable statistics.

The same set of counters is updated for packets received over any path of this LSP and over the lifetime of the LSP. In steady-state, the counters are updated for packets received over the active path of the LSP. The active path can be the primary path, one of the secondary paths, the FRR detour path, or the FRR bypass path when the tail-end node is also the MP.

When a hierarchy of LSPs is in use, statistics collection on the outermost label corresponding to the tunneling LSP and on the inner labels, corresponding to the tunneled LSPs are mutually exclusive. A consequence of this is that when the operator enables statistics collection on an RSVP LSP which is also used for tunneling LDP FECs with the LDP over RSVP feature, then statistics will be collected on the RSVP LSP only. There will be no statistics collected for an LDP FEC tunneled over this RSVP LSP and also egressing on the same node regardless if the operator enabled statistics collection on this FEC. When, the operator disables statistics collection on the RSVP LSP, then statistics collection, if enabled, will be performed on a tunneled LDP FEC.

The operator can enable statistics collection on a manual bypass terminating on the egress LER. However all LSPs which primary path is protected by the manual bypass will not collect statistics when they activate forwarding over the manual bypass. When, the operator disables statistics collection on the manual bypass LSP, then statistics collection on the protected LSP, if enabled, will continue when the bypass LSP is activated.

The no form of this command disables statistics for this RSVP LSP in the ingress data path and removes the accounting policy association from the LSP.

Parameters

sender-address ip-address

Specifies a string of 15 characters representing the IP address of the ingress LER for the LSP.

configure router mpls lsp

Description

This command creates an LSP that is either signaled dynamically by the router, or a statically provisioned MPLS-TP LSP.

When the LSP is created, the egress router must be specified using the to command and at least one primary or secondary path must be specified for signaled LSPs, or at least one working path for MPLS-TP LSPs. All other statements under the LSP hierarchy are optional.

LSPs are created in the administratively down (shutdown) state.

The no form of this command deletes the LSP. All configuration information associated with this LSP is lost. The LSP must be administratively shutdown before it can be deleted. The LSP must also be unbound from all SDPs before it can be deleted.

Parameters

lsp-name

Specifies the name that identifies the LSP. The LSP name can be up to 64 characters long and must be unique.

bypass-only

Defines an LSP as a manual bypass LSP exclusively. When a path message for a new LSP requests bypass protection, the PLR first checks if a manual bypass tunnel satisfying the path constraints exists. If one if found, the router selects it. If no manual bypass tunnel is found, the router dynamically signals a bypass LSP in the default behavior. The CLI for this feature includes a knob that provides the user with the option to disable dynamic bypass creation on a per node basis.

p2mp-lsp

Defines an LSP as a point-to-multipoint LSP. The following parameters can be used with a P2MP LSP: adaptive, adspec, cspf, exclude, fast-reroute, from, hop-limit, include, metric, retry-limit, retry-timer, resignal-timer. The following parameters cannot be used with a P2MP LSP: primary, secondary, to, dest-global-id, dest-tunnel-number, working-tp-path, protect-tp-path.

This option is not supported on the 7450 ESS.

mpls-tp src-tunnel-num

Defines an LSP as an MPLS-TP LSP. The src-tunnel-num is a mandatory create time parameter for mpls-tp LSPs, and has to be assigned by the user based on the configured range of tunnel IDs. The following parameters can only be used with an MPLS-TP LSP: to, dest-global-id, dest-tunnel-number, working-tp-path, protect-tp-path. Other parameters defined for the above LSP types cannot be used.

sr-te

Defines an LSP of type Segment Routing Traffic Engineering (SR-TE) LSP. The user can associate an empty path or a path with strict or loose explicit hops with the primary path of the SR-TE LSP. A hop which corresponds to an adjacency SID must be identified with its far-end host IP address (next-hop) on the subnet. If the local end host IP address is provided, this hop is ignored since this router can have multiple adjacencies (next-hops) on the same subnet. A hop which corresponds to a node SID is identified by the prefix address. The user is only allowed to configure a primary path for the SR-TE LSP.

Description

This command creates associations between one or more label switched paths (LSPs) and an Multi-Protocol Label Switching (MPLS) Service Distribution Point (SDP). This command is implemented only on MPLS-type encapsulated SDPs.

In MPLS SDP configurations either one or more LSP names can be specified or LDP can be enabled. The SDP ldp and lsp commands are mutually exclusive except if the mixed-lsp-mode option is also enabled. If an LSP is specified on an MPLS SDP, then LDP cannot be enabled on the SDP. To enable LDP on the SDP when an LSP is already specified, the LSP must be removed from the configuration using the no lsp lsp-name command.

Alternatively, if LDP is already enabled on an MPLS SDP, then an LSP cannot be specified on the SDP. To specify an LSP on the SDP, the LDP must be disabled or the mixed-lsp-mode option is also enabled. The LSP must have already been created in the config>router>mpls context. with a valid far-end IP address. RSVP must be enabled.

If no LSP is associated with an MPLS SDP, the SDP cannot enter the operationally up state. The SDP can be administratively enabled (no shutdown) with no LSP associations. The lsp-name may be shutdown, causing the association with the SDP to be operationally down (the LSP will not be used by the SDP).

Up to 16 LSP names can be entered on a single command line.

The no form of this command deletes one or more LSP associations from an SDP. If the lsp-name does not exist as an association or as a configured LSP, no error is returned. An lsp-name must be removed from all SDP associations before the lsp-name can be deleted from the system. The SDP must be administratively disabled (shutdown) before the last lsp-name association with the SDP is deleted.

Parameters

lsp-name

Specifies the name of the LSP to associate with the SDP. An LSP name is case sensitive and is limited to 32 ASCII 7-bit printable characters with no spaces. If an exact match of lsp-name does not already exist as a defined LSP, an error message is generated. If the lsp-name does exist and the LSP to IP address matches the SDP far-end IP address, the association is created.

Description

This command explicitly sets the forwarding class or subclass enqueuing priority when a packet is marked with a MPLS EXP bits specified. Adding a lsp-exp rule on the policy forces packets that match the MPLS LSP EXP specified to override the forwarding class and enqueuing priority based on the parameters included in the lsp-exp rule. When the forwarding class is not specified in the rule, a matching packet preserves (or inherits) the existing forwarding class derived from earlier matches in the classification hierarchy. When the enqueuing priority is not specified in the rule, a matching packet preserves (or inherits) the existing enqueuing priority derived from earlier matches in the classification hierarchy.

The lsp-exp-value is derived from the MPLS LSP EXP bits of the top label.

Multiple commands can be entered to define the association of some or all eight LSP EX bit values to the forwarding class.

The no form of this command removes the explicit lsp-exp classification rule from the SAP ingress policy. Removing the rule on the policy immediately removes the rule on all ingress SAPs using the policy.

This command applies to Ethernet Layer 2 SAPs only.

Parameters

lsp-exp-value

This value is a required parameter that specifies the unique MPLS LSP EXP value that will match the lsp-exp rule. If the command is executed multiple times with the same lsp-exp-value, the previous forwarding class and enqueuing priority is completely overridden by the new parameters or defined to be inherited when a forwarding class or enqueuing priority parameter is missing.

A maximum of eight lsp-exp rules are allowed on a single policy.

Values

0 to 7

fc fc-name

The value given for the fc-name parameter must be one of the predefined forwarding classes in the system. Specifying the fc-name is optional. When a packet matches the rule, the forwarding class is only overridden when the fc-name parameter is defined on the rule. If the packet matches and the forwarding class is not explicitly defined in the rule, the forwarding class is inherited based on previous rule matches.

The subclass-name parameter is optional and used with the fc-name parameter to define a pre-existing subclass. The fc-name and subclass-name parameters must be separated by a period (dot). If subclass-name does not exist in the context of fc -name, an error will occur.

Values

class[.subclass]

class: be, l2, af, l1, h2, ef, h1, nc

subclass: 29 characters max

priority

The priority parameter is used to override the default enqueuing priority for all packets received on an ingress SAP using this policy that match this rule. Specifying the priority is optional. When a packet matches the rule, the enqueuing priority is only overridden when the priority parameter is defined on the rule. If the packet matches and priority is not explicitly defined in the rule, the enqueuing priority is inherited based on previous rule matches.

high

The high parameter is used in conjunction with the priority parameter. Setting the enqueuing parameter to high for a packet increases the likelihood of enqueuing the packet when the ingress queue is congested. Ingress enqueuing priority only affects ingress SAP queuing. When the packet is placed in a buffer on the ingress queue, the significance of the enqueuing priority is lost.

low

The low parameter is used in conjunction with the priority parameter. Setting the enqueuing parameter to low for a packet decreases the likelihood of enqueuing the packet when the ingress queue is congested. Ingress enqueuing priority only affects ingress SAP queuing. When the packet is placed in a buffer on the ingress queue, the significance of the enqueuing priority is lost.

configure qos network ingress lsp-exp

Description

This command creates a mapping between the LSP EXP bits of the network ingress traffic and the forwarding class.

Ingress traffic that matches the specified LSP EXP bits will be assigned to the corresponding forwarding class. Multiple commands can be entered to define the association of some or all eight LSP EXP bit values to the forwarding class. For undefined values, packets are assigned to the forwarding class specified under the default-action command.

The no form of this command removes the association of the LSP EXP bit value to the forwarding class. The default-action then applies to that LSP EXP bit pattern.

Default

no lsp-exp

Parameters

lsp-exp-value

Specify the LSP EXP values to be associated with the forwarding class.

Values

0 to 8 (Decimal representation of three EXP bit field)

fc fc-name

Enter this required parameter to specify the fc-name that the EXP bit pattern will be associated with.

Values

Description

This command configures the initial LSP path retry-timer.

The new LSP path initial retry-timer is used instead of the retry-timer to abort the retry cycle when no RESV is received. The retry-timer exclusively governs the time between two retry cycles and to handle retrying of an LSP path in a failure case with PATH errors or RESVTear.

The intent is that the user can now control how many refreshes of the pending PATH state can be performed before starting a new retry-cycle with a new LSP ID. This is all done without affecting the ability to react faster to failures of the LSP path, which will continue to be governed by the retry-timer.

The no form of this command returns the timer to the default value.

Default

Description

This command configures the interval during which LSPs are sent from the interface.

To avoid overwhelming neighbors that have less CPU processing power with LSPs, the pacing interval can be configured to limit how many LSPs are sent during an interval. LSPs may be sent in bursts during the interval up to the configured limit. If a value of 0 is configured, no LSPs are sent from the interface.

If configured to the default LSP pacing interval of 100, LSPs are sent in 100 millisecond intervals.

The no form of this command reverts to the default value.

Note:

The IS-IS timer granularity is 100 ms. Timer values are rounded down to the nearest granularity, for example a configured value of 550 ms is internally rounded down to 500 ms.

Description

This command configures the interval at which LSPs are sent from the interface.

To avoid overwhelming neighbors that have less CPU processing power with LSPs, the pacing interval can be configured to limit how many LSPs are sent at the interval. LSPs are sent in bursts at the interval up to the configured limit. If a value of 0 is configured, no LSPs are sent from the interface.

If configured to the default LSP pacing interval of 100, LSPs are sent in 100 millisecond intervals.

The no form of this command reverts to the default value.

Note:

The IS-IS LSP pacing interval is 100 milliseconds for values < 100 milliseconds, and 1 second for values ≥ 100 milliseconds. For example, a pacing interval of 2 milliseconds means that a maximum of 50 LSPs are sent in a burst at 100 millisecond intervals. The default pacing interval of 100 milliseconds means that a maximum of 10 LSPs are sent in a burst at 1 second intervals.

Description

This command performs in-band LSP connectivity tests.

This command performs an LSP ping using the protocol and data structures defined in the RFC 8029, Detecting Multi-Protocol Label Switched (MPLS) Data Plane Failures.

The LSP ping operation is modeled after the IP ping utility which uses ICMP echo request and reply packets to determine IP connectivity.

In an LSP ping, the originating device creates an MPLS echo request packet for the LSP and path to be tested. The MPLS echo request packet is sent through the data plane and awaits an MPLS echo reply packet from the device terminating the LSP. The status of the LSP is displayed when the MPLS echo reply packet is received.

This command, when used with the static option, performs in-band on-demand LSP connectivity verification tests for static MPLS-TP LSPs. For other LSP types, the static option should be excluded and these are described elsewhere in this user guide.

The lsp-ping static command performs an LSP ping using the protocol and data structures defined in the RFC 8029, Detecting Multi-Protocol Label Switched (MPLS) Data Plane Failures, as extended by RFC 6426, MPLS On-Demand Connectivity Verification and Route Tracing.

In MPLS-TP, the echo request and echo reply messages are always sent in-band over the LSP, either in a G-ACh channel or encapsulated as an IP packet below the LSP label.

The timestamp format to be sent, and to be expected when received in a PDU, is as configured by the config>test-oam>mpls-time-stamp-format command. If RFC 4379 (obsoleted by RFC 8029) is selected, then the timestamp is in seconds and microseconds since 1900, otherwise it is in seconds and microseconds since 1970.

Values

ipv4 — Use an Associated Channel with IP encapsulation, as described in RFC 6426, Section 3.2.

non-ip — Do not use an Associated Channel, as described in RFC 6426, Section 3.1.

none — Use the Associated Channel mechanism described in RFC 6426, Section 3.3.

Default

non-ip

global-id

Specifies the MPLS-TP global ID for the far end node of the LSP under test. If this is not entered, then the dest-global-id is taken from the LSP context.

Values

0 to 4294967295

Default

0

node-id

Specifies the MPLS-TP global ID for the far end node of the LSP under test. If this is not entered, then the dest-global-id is taken from the LSP context.

Values

a.b.c.d, 1 to 4294967295

0

force

Allows LSP ping to test a path that is operationally down, including cases where MPLS-TP BFD CC/V is enabled and has taken a path down. This parameter is only allowed in the OAM context; it is not allowed for a test configured as a part of an SAA.

Default

disabled

path-type {active | working | protect}

The LSP path to test.

Values

active — The currently active path. If MPLS-TP linear protection is configured on the LSP, then this is the path that is selected by the MPLS-TP PSC protocol for sending user plane traffic. If MPLS-TP linear protection is not configured, then this is the working path.

working — The working path of the MPLS-TP LSP.

protect — The protect path of the MPLS-TP LSP.

Default

active

fc-name

Specifies the FC and profile parameters that are used to indicate the forwarding class and profile of the MPLS echo request packet.

When an MPLS echo request packet is generated in CPM and is forwarded to the outgoing interface, the packet is queued in the egress network queue corresponding to the specified fc and profile parameter values. The marking of the packet's EXP is dictated by the LSP-EXP mappings on the outgoing interface.

When the MPLS echo request packet is received on the responding node, The FC and profile parameter values are dictated by the LSP-EXP mappings of the incoming interface.

When an MPLS echo reply packet is generated in CPM and is forwarded to the outgoing interface, the packet is queued in the egress network queue corresponding to the FC and profile parameter values determined by the classification of the echo request packet, which is being replied to, at the incoming interface. The marking of the packet's EXP is dictated by the LSP-EXP mappings on the outgoing interface. The ToS byte is not modified. lsp-ping Request Packet and Behavior summarizes this behavior.

Table 7. lsp-ping Request Packet and Behavior

CPM (sender node)

Echo request packet:

  • packet {tos=1, fc1, profile1}

  • fc1 and profile1 are as entered by user in OAM command or default values

  • tos1 as per mapping of {fc1, profile1} to IP precedence in network egress QoS policy of outgoing interface

Outgoing interface (sender node)

Echo request packet:

  • packet queued as {fc1, profile1}

  • ToS field=tos1 not remarked

  • EXP=exp1, as per mapping of {fc1, profile1} to EXP in network egress QoS policy of outgoing interface

Incoming interface (responder node)

Echo request packet:

  • packet {tos1, exp1}

  • exp1 mapped to {fc2, profile2} as per classification in network QoS policy of incoming interface

CPM (responder node)

Echo reply packet:

  • packet{tos=1, fc2, profile2}

Outgoing interface (responder node)

Echo reply packet:

  • packet queued as {fc2, profile2}

  • ToS filed= tos1 not remarked (reply inband or out-of-band)

  • EXP=exp2, if reply is inband, remarked as per mapping of {fc2, profile2} to EXP in network egress QoS policy of outgoing interface

Incoming interface (sender node)

Echo reply packet:

  • packet {tos1, exp2}

  • exp2 mapped to {fc1, profile1} as per classification in network QoS policy of incoming interface

The LSP-EXP mappings on the receive network interface controls the mapping of the message reply at the originating router.

be, l2, af, l1, h2, ef, h1, nc

Default

be

profile {in | out}

Specifies the profile state of the MPLS echo request packet.

Default

out

interval

Specifies the time, in seconds, used to override the default request message send interval and defines the minimum amount of time that must expire before the next message request is sent.

Values

1 to 10

Default

1

send-count

Specifies the number of messages to send, expressed as a decimal integer. The send-count parameter is used to override the default number of message requests sent. Each message request must either time out or receive a reply before the next message request is sent. The message interval value must be expired before the next message request is sent.

Values

1 to 100

Default

1

octets

Specifies the MPLS echo request packet size in octets, expressed as a decimal integer. The request payload is padded with zeros to the specified size.

Values

1 to 9786

Default

configure router ldp lsp-bfd lsp-ping-interval

Description

This command configures the interval between periodic LSP ping messages for LSPs on which bfd-enable is configured. The LSP ping messages are used to bootstrap and maintain the LSP BFD session.

Configuring an interval of 0 seconds disables periodic LSP ping. An LSP ping message containing a bootstrap TLV will only be sent when the BFD session is first initialized.

In scaled environments, LSP BFD sessions should use longer intervals to reduce congestion and common resource loading. Unless required, the interval should not be set lower than 300 s.

The no form of this command restores the default interval.

Default

Description

Commands in this context configure LSP self-ping parameters.

LSP Self-ping checks that the datapath of an RSVP LSP has been programmed by all LSRs along its path before switching the traffic to it. If enabled, LSP Self-ping packets are sent periodically at a configurable interval following the receipt of the RESV message for an RSVP LSP path following an MBB or other event where the active path changes while the previous active path stayed up. The router will not switch traffic to the new path until an LSP Self-ping reply is received from the far-end LER.

When configured under the MPLS context, LSP Self-ping is enabled for all RSVP LSPs, unless it is explicitly disabled for a given LSP.

The no form of this command disables the system check for LSP Self-ping.

Description

This command performs an LSP traceroute using the protocol and data structures defined in IETF RFC 8029.

The LSP trace operation is modeled after the IP traceroute utility, which uses ICMP echo request and reply packets with increasing TTL values to determine the hop-by-hop route to a destination IP.

In an LSP trace, the originating device creates an MPLS echo request packet for the LSP to be tested with increasing values of the TTL in the outermost label. The MPLS echo request packet is sent through the data plane and awaits a TTL exceeded response or the MPLS echo reply packet from the device terminating the LSP. The devices that reply to the MPLS echo request packets with the TTL exceeded and the MPLS echo reply are displayed.

The downstream mapping TLV is used in lsp-trace to provide a mechanism for the sender and responder nodes to exchange and validate interface and label stack information for each downstream hop in the path of the LDP FEC an RSVP LSP, or a BGP IPv4 label route.

Two downstream mapping TLVs are supported. The original Downstream Mapping (DSMAP) TLV defined in RFC 4379 (obsoleted by RFC 8029) and the new Downstream Detailed Mapping (DDMAP) TLV defined in RFC 6424 AND RFC 8029. More details are provided in the DDMAP TLV sub-section below.

In addition, when the responder node has multiple equal cost next hops for an LDP FEC, a BGP label IPv4 prefix, an SR-ISIS node SID, an SR-OSPF node SID, or an SR-TE LSP, it replies in the Downstream Mapping TLV with the downstream information for each outgoing interface which is part of the ECMP next-hop set for the prefix. The downstream mapping TLV can further be used to exercise a specific path of the ECMP set using the path-destination option.

This command, when used with the static option, performs in-band on-demand LSP traceroute tests for static MPLS-TP LSPs. For other LSP types, the static option should be excluded and these are described elsewhere in this user guide.

The lsp-trace static command performs an LSP trace using the protocol and data structures defined in the RFC 8029, Detecting Multi-Protocol Label Switched (MPLS) Data Plane Failures, as extended by RFC 6426, MPLS On-Demand Connectivity Verification and Route Tracing.

In MPLS-TP, the echo request and echo reply messages are always sent in-band over the LSP, either in a G-ACh channel or encapsulated as an IP packet below the LSP label.

The timestamp format to be sent, and to be expected when received in a PDU, is as configured by the configure test-oam mpls-time-stamp-format command. If RFC 4379 (obsoleted by RFC 8029) is selected, the timestamp is in seconds and microseconds since 1900, otherwise it is in seconds and microseconds since 1970.

static

Specifies the selection of the target FEC Stack sub-type "Static LSP”.

assoc-channel {ipv4 | non-ip | none}

Specifies the launched echo request’s usage of the Associated Channel (ACH) mechanism, when testing an MPLS-TP LSP.

Values

ipv4 — Use the Associated Channel mechanism with IP encapsulation, as described in RFC 6426, Section 3.2.

non-ip — Do not use an Associated Channel, as described in RFC 6426, Section 3.1.

none — Use the Associated Channel mechanism described in RFC 6426, Section 3.3.

path-type {active | working | protect}

Specifies the LSP path to test.

Values

active — Specifies the currently active path. If MPLS-TP linear protection is configured on the LSP, then this is the path that is selected by the MPLS-TP PSC protocol for sending user plane traffic. If MPLS-TP linear protection is not configured, then this is the working path.

working — Specifies the working path of the MPLS-TP LSP.

protect — Specifies the protect path of the MPLS-TP LSP.

Default

active

downstream-map-tlv

Specifies which format of the downstream mapping TLV to use in the LSP trace packet. The DSMAP TLV is the original format in RFC 4379 (obsoleted by RFC 8029). The DDMAP is the new enhanced format specified in RFC 6424 and RFC 8029. The user can also choose not to include the downstream mapping TLV by entering the value none. When lsp-trace is used on a MPLS-TP LSP (static option), it can only be executed if the control-channel is set to none. In addition, the DSMAP/DDMAP TLV is only included in the echo request message if the egress interface is either a numbered IP interface, or an unnumbered IP interface. The TLV is not included if the egress interface is of type unnumbered-mpls-tp.

Values

ddmap: Sends a detailed downstream mapping TLV.

dsmap: Sends a downstream mapping TLV.

none: No mapping TLV is sent.

Default

Inherited from global configuration of downstream mapping TLV in option mpls-echo-request-downstream-map {dsmap | ddmap}.

fc-name

Specifies the FC and profile parameters are used to indicate the forwarding class and profile of the MPLS echo request packet.

When an MPLS echo request packet is generated in CPM and is forwarded to the outgoing interface, the packet is queued in the egress network queue corresponding to the specified FC and profile parameter values. The marking of the packet EXP is dictated by the LSP-EXP mappings on the outgoing interface.

When the MPLS echo request packet is received on the responding node, The FC and profile parameter values are dictated by the LSP-EXP mappings of the incoming interface.

When an MPLS echo reply packet is generated in CPM and is forwarded to the outgoing interface, the packet is queued in the egress network queue corresponding to the fc and profile parameter values determined by the classification of the echo request packet, which is being replied to, at the incoming interface. The marking of the packet's EXP is dictated by the LSP-EXP mappings on the outgoing interface. The ToS byte is not modified. lsp-trace Request Packet and Behavior summarizes this behavior.

Table 8. lsp-trace Request Packet and Behavior

CPM (sender node)

Echo request packet:

  • packet {tos=1, fc1, profile1}

  • fc1 and profile1 are as entered by user in OAM command or default values

  • tos1 as per mapping of {fc1, profile1} to IP precedence in network egress QoS policy of outgoing interface

Outgoing interface (sender node)

Echo request packet:

  • pkt queued as {fc1, profile1}

  • ToS field=tos1 not remarked

  • EXP=exp1, as per mapping of {fc1, profile1} to EXP in network egress QoS policy of outgoing interface

Incoming interface (responder node)

Echo request packet:

  • packet {tos1, exp1}

  • exp1 mapped to {fc2, profile2} as per classification in network QoS policy of incoming interface

CPM (responder node)

Echo reply packet:

  • packet {tos=1, fc2, profile2}

Outgoing interface (responder node)

Echo reply packet:

  • pkt queued as {fc2, profile2}

  • ToS filed= tos1 not remarked (reply inband or out-of-band)

  • EXP=exp2, if reply is inband, remarked as per mapping of {fc2, profile2} to EXP in network egress QoS policy of outgoing interface

Incoming interface (sender node)

Echo reply packet:

  • packet {tos1, exp2}

Values

be, l2, af, l1, h2, ef, h1, nc

Default

be

profile {in | out}

Specifies the profile state of the MPLS echo request packet.

Default

out

interval

Specifies the number of seconds to override the default request message send interval and defines the minimum amount of time that must expire before the next message request is sent.

If the interval is set to 1 second, and the timeout value is set to 10 seconds, then the maximum time between message requests is 10 seconds and the minimum is 1 second. This depends upon the receipt of a message reply corresponding to the outstanding message request.

Values

1 to 10

Default

1

no-response-count

Specifies the maximum number of consecutive MPLS echo requests, expressed as a decimal integer that do not receive a reply before the trace operation fails for a given TTL.

Values

1 to 255

Default

5

max-label-ttl

Specifies the maximum TTL value in the MPLS label for the LDP treetrace test, expressed as a decimal integer.

Values

1 to 255

Default

30

min-label-ttl

Specifies the minimum TTL value in the MPLS label for the LSP trace test, expressed as a decimal integer.

Values

1 to 255

Default

1

probes-per-hop

Specifies the probes per hop.

Values

1 to 10

Default

1

octets

Specifies the size in octets, expressed as a decimal integer, of the MPLS echo request packet, including the IP header but not the label stack. The request payload is padded with zeros to the specified size. Note that an OAM command is not failed if the user entered a size lower than the minimum required to build the packet for the echo request message. The payload is automatically padded to meet the minimum size.

Values

1 to 9786

Default

1

src-ip-address ip-address

Specifies the source IP address. This option is used when an OAM packet must be generated from a different address than the node’s system interface address. An example is when the OAM packet is sent over an LDP LSP and the LDP LSR-ID of the corresponding LDP session to the next-hop is set to an address other than the system interface address.

Values

ipv4-address: a.b.c.d

ipv6-address: x:x:x:x:x:x:x:x (eight 16-bit pieces)

x:x:x:x:x:x:d.d.d.d

x - [0 to FFFF]H

d - [0 to 255]D

timeout

Specifies the time, in seconds, used to override the default timeout value and is the amount of time that the router waits for a message reply after sending the message request. Upon the expiration of the message time out, the requesting router assumes that the message response is not received. A request timeout message is displayed by the CLI for each message request sent that expires. Any response received after the request times out is silently discarded.

Values

1 to 60

Default

Full Context

configure saa test type-multi-line lsp-trace

Description

This command creates the context to perform an LSP traceroute using the protocol and data structures defined in IETF RFC 4379 (obsoleted by RFC 8029).

Platforms

All

no lsp-wait

Context

[Tree] (config>service>vpls>spb>timers lsp-wait)

Full Context

configure service vpls spb timers lsp-wait

Description

This command is used to customize LSP generation throttling. Timers that determine when to generate the first, second and subsequent LSPs can be controlled with this command. Subsequent LSPs are generated at increasing intervals of the second lsp-wait timer until a maximum value is reached.

Note:

The IS-IS timer granularity is 100 ms. Timer values are rounded down to the nearest granularity, for example a configured value of 550 ms is internally rounded down to 500 ms.

Parameters

lsp-wait

Specifies the maximum interval in milliseconds between two consecutive occurrences of an LSP being generated.

Values

10 to 120000

Default

5000

lsp-initial-wait

Specifies the initial LSP generation delay in milliseconds. Values < 100 ms are internally rounded down to 0, so that there is no added initial LSP generation delay.

Values

10 to 100000

Default

10

lsp-second-wait

Specifies the hold time in milliseconds between the first and second LSP generation.

Values

10 to 100000

Default

Description

This command is used to customize LSP generation throttling. Timers that determine when to generate the first, second, and subsequent LSPs can be controlled with this command. Subsequent LSPs are generated at increasing intervals of the second lsp-wait timer until a maximum value is reached.

Note:

The timer granularity is 10 ms if the value is < 500 ms, and 100 ms if the value is ≥ 500 ms. Timer values are rounded down to the nearest granularity, for example a configured value of 550 ms is internally rounded down to 500 ms.

Parameters

lsp-wait

Specifies the maximum interval, in milliseconds, between two consecutive occurrences of an LSP being generated.

Values

10 to 120000

Default

5000

initial-wait

Specifies the initial LSP generation delay, in milliseconds. Values less than 100 ms are internally rounded down to 0, so that there is no added initial LSP generation delay.

Values

10 to 100000

Default

10

second-wait

Specifies the hold time, in milliseconds, between the first and second LSP generation.

Description

This command customizes LSP generation throttling. Timers that determine when to generate the first, second and subsequent LSPs can be controlled with this command. Subsequent LSPs are generated at increasing intervals of the second lsp-wait timer until a maximum value is reached.

Note:

The timer granularity is 10 ms if the value is less than 500 ms, and 100 ms if the value is greater than or equal to 500 ms. Timer values are rounded down to the nearest granularity, for example a configured value of 550 ms is internally rounded down to 500 ms.

Default

lsp-wait 5000 lsp-initial-wait 10 lsp-second-wait 1000

Parameters

lsp-max-wait

Specifies the maximum interval in milliseconds between two consecutive occurrences of an LSP being generated.

Values

10 to 120000

initial-wait

Specifies the initial LSP generation delay in milliseconds. Values less than 100 ms are internally rounded down to 0, so that there is no added initial LSP generation delay.

Values

10 to 100000

second-wait

Specifies the hold time in milliseconds between the first and second LSP generation.

Values

10 to 100000

Full Context

configure router ttl-propagate lsr-label-route

Description

This command configures the TTL propagation for transit packets at a router acting as an LSR for a BGP label route.

When an LSR swaps the BGP label for a ipv4 prefix packet, therefore acting as a ABR, ASBR, or data-path Route-Reflector (RR) in the base routing instance, or swaps the BGP label for a vpn-ipv4 or vpn-ipv6 prefix packet, therefore acting as an inter-AS Option B VPRN ASBR or VPRN data path Route-Reflector (RR), the all value of this command enables TTL propagation of the decremented TTL of the swapped BGP label into all outgoing LDP or RSVP transport labels.

When an LSR swaps a label or stitches a label, it always writes the decremented TTL value into the outgoing swapped or stitched label. What this feature controls is whether this decremented TTL value is also propagated to the transport label stack pushed on top of the swapped or stitched label.

The none value reverts to the default mode which disables TTL propagation. This changes the existing default behavior which propagates the TTL to the transport label stack. When a customer upgrades, the new default becomes in effect. This command does not have a no version.

This feature also controls the TTL propagation at an LDP-BGP stitching LSR in the LDP to BGP stitching direction. It also controls the TTL propagation in Carrier Supporting Carrier (CsC) VPRN at both the CsC CE and CsC PE.

SR OS does not support ASBR or data path RR functionality for labeled IPv6 routes in the global routing instance (6PE). As such the CLI command of this feature has no impact on prefix packets forwarded in this context.

Default

lsr-label-route none

Parameters

none

Specifies that the TTL of the swapped label is not propagated into the transport label stack.

all

Specifies that the TTL of the swapped label is propagated into all labels of the transport label stack.

Description

This command specifies whether the IP header is used in the LAG and ECMP LSR hashing algorithm. This is the per interface setting.

Default

no lsr-load-balancing

Parameters

lbl-only

Only the label is used in the hashing algorithm.

lbl-ip

The IP header is included in the hashing algorithm.

ip-only

The IP header is used exclusively in the hashing algorithm.

eth-encap-ip

The hash algorithm parses down the label stack and once it hits the bottom, the stack assumes Ethernet II non-tagged/dot1q or qinq header follows. At the expected Ethertype offset location, algorithm checks whether the value present is IPv4/v6 (0x0800 or 0x86DD). If the check passes, the hash algorithm checks the first nibble at the expected IP header location for IPv4/IPv6 (0x0100/0x0110). If the secondary check passes, the hash is performed using IP SA/DA fields in the expected IP header; otherwise (if any of the checks failed) label-stack hash is performed.

Full Context

configure system load-balancing lsr-load-balancing

Description

This command configures system-wide LSR load balancing. Hashing can be enabled on the label stack and/or IP header at an LSR for spraying labeled IP packets over multiple equal cost paths and/or over multiple links of a LAG group.

The LSR hash routine operates on the label stack and the IP header if a packet is IPv4. An LSR will consider a packet to be IPv4 if the first nibble following the bottom of the label stack is 4. The hash on label and IPv4 and IPv6 headers can be enabled or disabled at the system level or incoming network IP interface level.

Default

no lsr-load-balancing

Full Context

configure qos adv-config-policy child-control bandwidth-distribution lub-init-min-pir

Description

This command enables new queues associated with a LUB context to use a minimum PIR similar to the effect of the limit-pir-zero-drain command. When a queue is initially created in a LUB context, it defaults to a zero value PIR until H-QoS has an opportunity to configure an offered rate based operational PIR. Enabling this command forces a minimum rate operational PIR to be applied to the queue for use by enqueued packets prior to an H-QoS iteration.

The no form of this command reverts to default behavior.

Default

no lub-init-min-pir
