Context
[Tree] (config>filter>ip-filter>entry>action l2-aware-nat-bypass)
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.

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.
- 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.
- 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.
- restrict same-neighbor-as
-
Specifies that the non-best path must have the same neighbor AS in its AS path as the best path.
- restrict exact-as-path-as
-
Specifies that the non-best path must have the same AS path as the best path.
- unequal-cost

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.
- 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.

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.

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 on 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).
- 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.
- system-id
-
Specifies a 6 byte value expressed in the same notation as MAC address.
- remote-lag-id
-
Specifies the LAG ID on the remote system.
- 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.
- 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.

configure lag
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.
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.
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.
- 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>”.

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-set value 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.

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.
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.

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.

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.
- 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.

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 or the mixed-lsp-mode option is also enabled.
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. The LSP must have already been created in the config>router>mpls context with a valid far-end IP address. The above rules are relaxed when the mixed-lsp option is enabled on the SDP.

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 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
Parameters
- seconds
-
Specifies the time interval for the IGP-LDP synchronization timer.

Description
This command allows the user to perform a single run of the LDP ECMP OAM tree trace to discover all ECMP paths of an LDP FEC.
Parameters
- ip-prefix/mask
-
Specifies the address prefix and subnet mask of the target BGP IPv4 label route.
- 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.
- 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.

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.
- 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.

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.

configure router mpls lsp least-fill
configure router mpls lsp-template 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

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.
Default

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.
Default
leave-time 30
Parameters
- value

configure qos network ingress ler-use-dscp
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).

Description
This command overrides the maximum and CIR rate parameters for a specific priority level on the port or channel’s port scheduler instance. When the level command is executed for a priority level, the corresponding priority level command in the port-scheduler-policy associated with the port is ignored.
The override level command supports the keyword max for the rate and cir parameter. When executing the level override command, at least the rate or cir keywords and associated parameters must be specified for the command to succeed.
The no form of this command removes the local port priority level rate overrides. Once removed, the port priority level will use the port scheduler policies level command for that priority level.
Parameters
- priority-level
-
Identifies which of the eight port priority levels are being overridden.
- pir-rate
-
Overrides the port scheduler policy’s maximum level rate and requires either the max keyword or a rate defined in kilobits per second to follow.
- cir-rate
-
Overrides the port scheduler policy’s within-cir level rate and requires either the max keyword or a rate defined in kilobits per second to follow.
- pir-percent
-
Specifies the PIR as a percentage.
- cir-percent
-
Specifies the CIR as a percentage.
- max
-
removes any existing rate limit imposed by the port scheduler policy for the priority level allowing it to use as much total bandwidth as possible.

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:

Description
This command configures the amount of bandwidth available within a given bundle for MC traffic for a specified level. The amount of allowable BW for the specified level is expressed in kb/s and this can be defined for up to eight different levels.
If no bandwidth is defined for a given level then no limit is applied.
The no form of this command removes the level from the configuration.
Parameters
- level
-
Specifies the bandwidth for a given level. Level 1 has the highest priority. Level 8 has the lowest priority.
- bw bandwidth
-
Specifies the bandwidth, in kb/s, for the level.

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.
- pir-rate
-
Specifies the total bandwidth limits allocated to priority-level, in kilobits per second.
- pir-percent
-
Specifies the percent bandwidth limits allocated to priority-level.
- 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.
- cir-percent
-
Specifies the percent bandwidth limits allocated to priority-level.
- 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.
- monitor-threshold percent
-
Specifies the percent of the configured rate. If the offered rate exceeds the configured threshold, a counter monitoring the threshold will be increased.
