Context

[Tree] (config>service>vprn>log>syslog facility)

Full Context

configure service vprn log syslog facility

Description

This command configures the facility code for messages sent to the syslog target host.

Multiple syslog IDs can be created with the same target host but each syslog ID can only have one facility code. If multiple facility codes are entered, the last facility-code entered overwrites the previous facility-code.

If multiple facilities need to be generated for a single syslog target host, then multiple log-id entries must be created, each with its own filter criteria to select the events to be sent to the syslog target host with a given facility code.

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

Default

local7 — Syslog entries are sent with the local7 facility code.

Parameters

syslog-facility

Specifies syslog facility name represents a specific numeric facility code. The code should be entered in accordance with the syslog RFC. However, the software does not validate if the facility code configured is appropriate for the event type being sent to the syslog target host.

Values

kernel, user, mail, systemd, auth, syslogd, printer, netnews, uucp, cron, authpriv, ftp, ntp, logaudit, logalert, cron2, local0, local1, local2, local3, local4, local5, local6, local7

Context

[Tree] (config>card>xiom fail-on-error)

[Tree] (config>card fail-on-error)

Full Context

configure card xiom fail-on-error

configure card fail-on-error

Description

This command controls the behavior of the card when any one of a specific set of card level errors is encountered in the system. When the fail-on-error command is enabled, and any one (or more) of the specific errors is detected, then the Operational State of the card is set to Failed. This Failed state will persist until the clear card command is issued (reset) or the card is removed and re-inserted (re-seat). If the condition persists after re-seating the card, then Nokia support should be contacted for further investigation.

Enabling fail-on-error is only recommended when the network is designed to be able to route traffic around a failed card (redundant cards, nodes or other paths exist).

The list of specific errors includes:

• CHASSIS event ID# 2063 – tmnxEqCardPChipMemoryEvent

• CHASSIS event ID# 2076 – tmnxEqCardPChipCamEvent

• CHASSIS event ID# 2059 – tmnxEqCardPChipError (for ingress Ethernet only)

• CHASSIS event ID# 2098 tmnxEqCardQChipBufMemoryEvent

• CHASSIS event ID# 2099 tmnxEqCardQChipStatsMemoryEvent

• CHASSIS event ID# 2101 tmnxEqCardQChipIntMemoryEvent

• CHASSIS event ID# 2103 tmnxEqCardChipIfCellEvent

On platforms without independent IOM/IMM and CPM cards, the node is rebooted if fail-on-error is enabled and one of the card level errors is encountered.

The tmnxEqCardPChipError is only considered as a trigger for card fail-on-error for ingress FCS errors (not egress FCS errors), and only for Ethernet MDAs or IMMs.

Note that upon the detection of the event/error in the system, the reporting of the event (logs) and the fail-on-error behavior of the card are independent. Log event control configuration will determine whether the events are reported in logs (or SNMP traps, and so on) and the fail-on-error configuration will determine the behavior of the card. This implies that the card can be configured to fail-on-error even if the events are suppressed (some may be suppressed in the system by default). In order to facilitate post-failure analysis, Nokia recommends that you enable the reporting of the specific events/errors ( configure log event-control) when fail-on-error is enabled.

Context

[Tree] (config>card>mda fail-on-error)

Full Context

configure card mda fail-on-error

Description

This command enables the fail-on-error feature. If an MDA is experiencing too many Egress XPL Errors, this feature causes the MDA to fail. This can force an APS switchover or traffic re-route. The purpose of this feature is to avoid situations where traffic is forced to use a physical link that suffers from errors but is still technically operational.

The feature uses values configured in the config>card>mda>egress-xpl context. When this feature is enabled on a MDA, if window consecutive minutes pass in which the MDA experiences more than threshold Egress XPL Errors per minute, then the MDA will be put in the failed state.

The no form of this command disables the feature on the MDA.

configure isa application-assurance-group fail-to-open

Description

This command configures the mode of operation during an operational failure of this application assurance group when no application assurance engines are available to service traffic. When enabled, all traffic that was to be inspected will be dropped. When disabled, all traffic that was to be inspected will be forwarded without any inspection as if the group was not configured at all.

Context

[Tree] (config>isa>nat-group failed-mda-limit)

Full Context

configure isa nat-group failed-mda-limit

Description

This command configures the maximum number of supported simultaneously failures in the active-active intra-chassis NAT redundancy model. Traffic from the failed ISAs is distributed over the remaining ISA in the system. Memory resources are reserved in every ISA to accommodate new mappings from the failed ISA. However, bandwidth is not reserved and each ISA operates at max speed in all conditions (with failure or without the failure).

NAT translations are not preserved across switchovers and consequently they will have to be re-initiated by the clients.

For this command to take effect, the intra-chassis redundancy mode must be set to active-active ( config>isa>nat-group>redundancy active-active).

Default

no failed-mda-limit

Parameters

number

Specifies the number of simultaneous ISA failures supported in active-active intra-chassis NAT redundancy model.

[Tree] (config>router>mpls>lsp>bfd failure-action)

Full Context

configure router mpls lsp bfd failure-action

Description

This command configures what action occurs when LSP BFD fails on an RSVP, SR-TE, or LDP LSP.

A failure action of down means an LSP is marked as unusable in TTM. If it appears as a shortcut in RTM, the route is removed. This failure action can only be configured on RSVP LSPs.

A failure action of failover causes the active path of an RSVP LSP to switch to the secondary or next-preference available secondary path. This option is only available for RSVP LSPs. It is not applicable to one-hop-p2p and mesh-p2p auto LSPs.

A failure action of failover-or-down means that a switchover from the active path is triggered on failure of the BFD session on the active path (primary or standby). If there is no available path to switch to, then the LSP is taken operationally down. For RSVP-TE LSPs, this failure action causes the two best-preference standby paths to be programmed in the data path, in addition to the primary.

The system generates an SNMP trap if BFD goes down on an LSP, regardless of whether a failure action is configured or not.

The no form of this command removes the failure action.

Default

no failure-action

Parameters

down

Specifies that the LSP will be marked as unusable in the TTM. If it appears as a shortcut in RTM, then the route will be removed.

failover

Specifies that the active path of an RSVP LSP will switch to the secondary path or next-preference available secondary path. This option is only available for RSVP LSPs. It is not applicable in the LSP template.

failover-or-down

Specifies that the active path of an SR-TE or RSVP-TE LSP switches to the secondary or next-preference available secondary path, or for the LSP to go operationally down if no other path is available.

[Tree] (config>mcast-mgmt>bw-plcy falling-percent-reset)

Full Context

configure mcast-management bandwidth-policy falling-percent-reset

Description

This command is configures the percentage of bandwidth decrease that must occur to reset the dynamic bandwidth monitoring function for a multicast channel. When a channel is configured to use the ingress dynamic bandwidth as the in-use bandwidth for ingress multicast path management, the system maintains a sliding window in time that defines how long the last highest bandwidth value associated with the channel should be used. The sliding window duration is derived from the channels bw-activity dynamic falling-delay parameter within the multicast information policy. Each time the system detects a current bandwidth for a channel that is equal to or greater than the current highest bandwidth for the channel, the sliding window is reset and the highest value is used when managing the ingress multicast paths. If the system does not detect a higher or equal bandwidth value for the channel within the window period, the system resets the sliding window and uses the next highest rate seen during the duration of the window period. In this way, the system delays relinquishing bandwidth for a dynamic bandwidth channel for a configurable period. If a momentary fluctuation (decrease) in ingress bandwidth occurs, the system ignores the bandwidth change.

While this is useful for momentary fluctuations in bandwidth, it may be desirable to react faster when the current bandwidth monitored for a channel drops significantly relative to the currently in-use bandwidth. When the bandwidth decrease is equal to or greater than the falling-percent-reset value, the system immediately stops using the highest bandwidth and starts using the current bandwidth while resetting the sliding window.

If falling-percent-reset is set to 50%, when the current ingress dynamic bandwidth is 50% of the current in-use highest bandwidth, the system immediately uses the current dynamic ingress bandwidth as the highest bandwidth for the channel.

By default, the falling-percent-reset is 50% when a new bandwidth policy is created. The default bandwidth policy also has a hard configured value of 50%. Setting falling-percent-reset to 100 is equivalent to specifying no falling-percent-reset.

The no form of this command restores the default value of 50%.

Default

falling-percent-reset 50

Parameters

percent-of-highest

The percent-of-highest parameter is required and defines the percentage of decline between the current ingress dynamic bandwidth and the current in-use highest bandwidth at which the system resets the dynamic ingress bandwidth monitoring for the channel. When reset in this case, the system uses the current ingress dynamic bandwidth as the highest rate and continues monitoring. The parameter must be defined as an integer value representing a percentage.

Values

1 to 100 percent

Full Context

configure router mpls lsp-template family

Description

This command specifies if the lsp-template is for use in IPv4 or IPv6 SR-TE LSP.

This command is optional in a IPv4 SR-TE auto-LSP but must be set to ipv6 value in a IPv6 SR-TE auto-LSP. By default, this command is set to ipv4 value for backward compatibility.

When establishing both IPv4 and IPv6 SR-TE mesh auto-LSPs with the same parameters and constraints, a separate LSP template of type mesh-p2p-srte must be configured for each address family with the family CLI leaf set to the IPv4 or IPv6 value. SR-TE one-hop auto-LSPs can only be established for either IPv4 or IPv6 family, but not both. The family leaf in the LSP template of type one-hop-p2p-srte should be set to the desired IP family value.

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

Default

family ipv4

Parameters

ipv4

Specifies the lsp-template is for use in IPv4 SR-TE LSP.

Full Context

configure mirror mirror-dest remote-source far-end

Description

This command is used on a destination router in a remote mirroring solution. See the description for the remote-source command for additional information.

When using L2TPv3, MPLS-TP or LDP IPv6 LSP SDPs in the remote mirroring solution, the destination node should be configured with remote-src>spoke-sdp entries. For all other types of SDPs, remote-source>far-end entries are used.

Up to 50 far-end entries can be specified.

The no form of this command removes the IP address from the remote source configuration.

Parameters

ip-address

Specifies the service IP address (system IP address) of the remote device sending mirrored traffic to this mirror destination service. If 0.0.0.0 is specified, any remote is allowed to send to this service.

Values

1.0.0.1 to 223.255.255.254

vc-id

Specifies the virtual circuit identifier of the remote source. For mirror services, the vc-id defaults to the service-id. However, if the vc-id is being used by another service a unique vc-id is required to create an SDP binding. For this purpose the mirror service SDP bindings accepts vc-ids. This VC ID must match the VC ID used on the spoke SDP that is configured on the source router.

ingress-vc-label

Specifies the ingress service label for mirrored service traffic on the far end device for manually configured mirror service labels.

The defined ing-svc-label is entered into the ingress service label table which causes ingress packet with that service label to be handled by this mirror destination service.

The specified ing-svc-label must not have been used for any other service ID and must match the egress service label being used on the spoke SDP that is configured on the source router. It must be within the range specified for manually configured service labels defined on this router. It may be reused for other far end addresses on this mirror-dest-service-id.

Values

2048 to 18431

tldp

Specifies that the label is obtained through signaling via the LDP.

icb

Specifies that the remote source is an inter-chassis backup SDP binding.

[Tree] (config>service>sdp far-end)

Full Context

configure service sdp far-end

Description

This command configures the system IP address of the far-end destination router for the Service Distribution Point (SDP) that is the termination point for a service.

The far-end IP address must be explicitly configured. The destination IP address must be that of an SR OS and for a GRE SDP it must match the system IP address of the far end router.

If the SDP uses GRE for the destination encapsulation, the IP address is checked against other GRE SDPs to verify uniqueness. If the IP address is not unique within the configured GRE SDPs, an error is generated and the IP address is not associated with the SDP. The local device may not know whether the IP address is actually a system IP interface address on the far-end device.

If the SDP uses MPLS encapsulation, the far-end address is used to check LSP names when added to the SDP. If the ‟ to IP address” defined within the LSP configuration does not exactly match the SDP far-end address, the LSP will not be added to the SDP and an error will be generated. Alternatively, an SDP that uses MPLS can have an MPLS-TP node with an MPLS-TP node-id and (optionally) a global ID. In this case, the SDP must use an MPLS-TP LSP and the SDP signaling parameter must be set to off.

An SDP cannot be administratively enabled until a far-end ip-address or MPLS-TP node-id is defined. The SDP is operational when it is administratively enabled ( no shutdown) and the far-end ip-address is contained in the IGP routing table as a host route. OSPF ABRs should not summarize host routes between areas. This can cause SDPs to become operationally down. Static host routes (direct and indirect) can be defined in the local device to alleviate this issue.

On a tunnel configured as SDP with delivery type of eth-gre-bridged, this command designates L2oGRE tunnel end points. This is the only configuration option allowed for this type of SDP.

The no form of this command removes the currently configured destination IP address for the SDP. The ip-address parameter is not specified and will generate an error if used in the no far-end command. The SDP must be administratively disabled using the config service sdp shutdown command before the no far-end command can be executed. Removing the far-end IP address will cause all lsp-name associations with the SDP to be removed.

Parameters

far-end

Specifies the far-end termination point for the GRE tunnel.

ip-address | ipv6-address

Specifies a IPv4 or IPv6 address of the far-end SR OS for the SDP in dotted decimal notation.

node-id

Specifies the MPLS-TP Node ID of the far-end system for the SDP, either in dotted decimal notation (a.b.c.d) or an unsigned 32-bit integer (1 to 4294967295). This parameter is mandatory for an SDP using an MPLS-TP LSP.

global-id

Specifies a MPLS-TP Global ID of the far-end system for the SDP, in an unsigned 32-bit integer (0 to 4294967295). This parameter is optional for an SDP using an MPLS-TP LSP. If not entered, a default value for the Global ID of ‛0’ is used. A global ID of ‛0’ indicates that the far-end node is in the same domain as the local node. The user must explicitly configure a Global ID if its value is non-zero.

Context

[Tree] (config>router>ldp fast-reroute)

Full Context

configure router ldp fast-reroute

Description

This command enables LDP Fast-Reroute (FRR) procedures. When enabled, LDP uses both the primary next-hop and LFA next-hop, when available, for resolving the next-hop of an LDP FEC against the corresponding prefix in the routing table. This will result in LDP programming a primary NHLFE and a backup NHLFE into the forwarding engine for each next-hop of a FEC prefix for the purpose of forwarding packets over the LDP FEC.

When any of the following events occurs, LDP instructs in the fast path the forwarding engines to enable the backup NHLFE for each FEC next-hop impacted by this event:

• An LDP interface goes operationally down, or is admin shutdown.

• An LDP session to a peer went down as the result of the Hello or Keep-Alive timer expiring.

• The TCP connection used by a link LDP session to a peer went down, due say to next-hop tracking of the LDP transport address in RTM, which brings down the LDP session.

• A BFD session, enabled on a T-LDP session to a peer, times-out and as a result the link LDP session to the same peer and which uses the same TCP connection as the T-LDP session goes also down.

• A BFD session enabled on the LDP interface to a directly connected peer, times out and brings down the link LDP session to this peer.

The tunnel-down-dump-time option or the label-withdrawal-delay option, when enabled, does not cause the corresponding timer to be activated for a FEC as long as a backup NHLFE is still available.

Because LDP can detect the loss of a neighbor/next-hop independently, it is possible that it switches to the LFA next-hop while IGP is still using the primary next-hop. Also, when the interface for the previous primary next-hop is restored, IGP may re-converge before LDP completed the FEC exchange with it neighbor over that interface. This may cause LDP to de-program the LFA next-hop from the FEC and blackhole traffic. In order to avoid this situation, it is recommended to enable IGP-LDP synchronization on the LDP interface.

When the SPF computation determines there is more than one primary next-hop for a prefix, it will not program any LFA next-hop in RTM. Thus, the LDP FEC will resolve to the multiple primary next-hops that provide the required protection.

The backup-sr-tunnel option enables the use of SR tunnel, as a remote LFA or TI-LFA backup tunnel next-hop by an LDP FEC.

As a pre-requisite, the user must enable the stitching of LDP and SR in the LDP-to-SR direction. That is because the LSR must perform the stitching of the LDP ILM to SR tunnel when the primary LDP next-hop of the FEC fails. Thus LDP must listen to SR tunnels programmed by the IGP in TTM but the mapping server feature is not required.

Assuming the following:

• the backup-sr-tunnel option is enabled in LDP

• the {loopfree-alternates remote-lfa} and/or the {loopfree-alternates ti-lfa} option is enabled in the IGP instance

• LDP was able to resolve the primary next-hop of the LDP FEC in RTM

IGP SPF will run both the base LFA and the TI-LFA algorithms and if it does not find a backup next-hop for a prefix of an LDP FEC, it will also run the remote LFA algorithm. If IGP finds a TI-LFA or a remote LFA tunnel next-hop, LDP programs the primary next-hop of the FEC using a LDP NHLFE and programs the LFA backup next-hop using a LDP NHLFE pointing to the SR tunnel endpoint. Note that the LDP packet is not ‟tunneled” over the SR tunnel. The LDP label is actually stitched to the segment routing label stack. LDP points both the LDP ILM and the LTN to the backup LDP NHLFE which itself uses the SR tunnel endpoint.

The behavior of the feature is thus similar to the LDP-to-SR stitching feature, except the behavior is augmented to allow the stitching of an LDP ILM/LTN to a SR tunnel also when the primary LDP next-hop of the FEC fails.

If the LDP FEC primary next-hop failed and LDP has pre-programmed a remote LFA or TI-LFA next-hop with a LDP backup NHLFE pointing to SR tunnel, the LDP ILM/LTN switches to it. Note that if for some reason the failure impacted only the LDP tunnel primary next-hop but not the SR tunnel primary next-hop, the LDP backup NHLFE will effectively point to the primary next-hop of the SR tunnel and traffic of the LDP ILM/LTN will follow this path instead of the TI-LFA or remote LFA next-hop of the SR tunnel until the latter is activated.

This feature is limited to IPv4 /32 prefixes in both LDP and SR.

The no form of this command disables the use of SR tunnels as backups for LDP FECs and disables LDP FRR.

configure router mpls lsp fast-reroute

configure router mpls lsp-template fast-reroute

Description

This command creates a pre-computed detour LSP from each node in the path of the LSP. In case of failure of a link or LSP between two nodes, traffic is immediately rerouted on the pre-computed detour LSP, thus avoiding packet-loss.

When fast-reroute is enabled, each node along the path of the LSP tries to establish a detour LSP as follows:

• Each upstream node sets up a detour LSP that avoids only the immediate downstream node, and merges back on to the actual path of the LSP as soon as possible.

  If it is not possible to set up a detour LSP that avoids the immediate downstream node, a detour can be set up to the downstream node on a different interface.

• The detour LSP may take one or more hops (see config>router>mpls>lsp hop-limit, config>router>mpls>lsp>primary-p2mp-instance hop-limit) before merging back on to the main LSP path.

• When the upstream node detects a downstream link or node failure, the ingress router switches traffic to a standby path if one was set up for the LSP.

Fast reroute is available only for the primary path. No configuration is required on the transit hops of the LSP. The ingress router will signal all intermediate routers using RSVP to set up their detours. TE must be enabled for fast-reroute to work.

If an LSP is configured with fast-reroute frr-method specified but does not enable CSPF, then global revertive will not be available for the LSP to recover.

The no form of the fast-reroute command removes the detour LSP from each node on the primary path. This command will also remove configuration information about the hop-limit and the bandwidth for the detour routes.

The no form of fast-reroute hop-limit command reverts to the default value.

Default

no fast-reroute — When fast-reroute is specified, the default fast-reroute method is one-to-one.

Parameters

frr-method

Configures the fast-reroute method.

Values

one-to-one — In the one-to-one technique, a label switched path is established which intersects the original LSP somewhere downstream of the point of link or node failure. For each LSP which is backed up, a separate backup LSP is established.

Values

facility — This option, sometimes called many-to-one, takes advantage of the MPLS label stack. Instead of creating a separate LSP for every backed-up LSP, a single LSP is created which serves to backup up a set of LSPs. This LSP tunnel is called a bypass tunnel.

The bypass tunnel must intersect the path of the original LSP(s) somewhere downstream of the point of local repair (PLR). Naturally, this constrains the set of LSPs being backed-up through that bypass tunnel to those that pass through a common downstream node. All LSPs which pass through the PLR and through this common node which do not also use the facilities involved in the bypass tunnel are candidates for this set of LSPs.

configure qos adv-config-policy child-control offered-measurement fast-start

Description

This command is used to enable fast detection of initial bandwidth on a child policer or queue associated with the policy. Multiple offered rate counter reads may be performed per the sampling interval. The system accumulates these counter values and evaluates the delta at the conclusion of the sampling interval. When fast-start is enabled, the system identifies all children associated with the policy that enter the inactive state (current offered rate is zero). Any inactive ‛fast start’ child that has a positive offered counter during a sampling period bypasses the normal sampling interval and does an immediate offered rate evaluation.

This option is intended for use with children that would benefit from faster than normal startup detection, typically those of a real-time nature.

When this parameter is not enabled, the system uses the normal sampling interval behavior of both newly active and currently active children.

The no form of this command is used to restore the sampling-interval-based offered rate evaluation for newly active children.

Description

This command is used to enable fast detection of lack of offered rate on a child policer or queue associated with the policy. Multiple offered rate counter reads may be performed per sampling interval. The system accumulates these counter values and evaluates the delta at the conclusion of the sampling interval. When fast-stop is enabled, the system bypasses the sampling interval for any currently active ‛fast stop’ child that has a zero offered counter measurement and does an immediate offered rate evaluation using the zero value.

This option is intended for use with children where other children would benefit from faster than normal inactive detection, typically those of a real-time nature.

When this parameter is not enabled, the system uses the normal sampling interval behavior of both newly inactive and currently active children.

Full Context

configure router mpls class-forwarding-policy fc

Description

This command configures the mapping of FCs to up to six forwarding sets for the class-based forwarding (CBF) of an LDP FEC or a BGP prefix over IGP shortcuts.

All FCs are mapped to set 1 as soon as the policy is created. The user can then make changes to the mapping of FCs as required. An FC that is not added to the class forwarding policy is thus always mapped to set 1. An FC can only be mapped to one forwarding set. One or more FCs can map to the same set. The user can indicate the initial default set by including the default-set option.

The default forwarding set forwards packets of an FC when all LSPs of the forwarding set that the FC maps to become operationally down. The router uses the user-configured default set as the initial default set if no default is configured; otherwise, it elects the lowest numbered set as the default forwarding set in a class forwarding policy. When the last LSP in a default forwarding set goes into an operationally down state, the router designates the next lowest numbered set as the new default forwarding set.

Parameters

{be | l2 | af | l1 | h2 | ef | h1 | nc}

Specifies the name of the forwarding class.

Full Context

configure mirror mirror-dest fc

Description

This command specifies a forwarding class for all mirrored packets transmitted to the destination SAP or SDP overriding the default (be) forwarding class. All packets are sent with the same class of service to minimize out-of-sequence issues. The mirrored packet does not inherit the forwarding class of the original packet.

When the destination is on a SAP, a single egress queue is created that pulls buffers from the buffer pool associated with the fc-name.

When the destination is on an SDP, the fc-name defines the DiffServ-based egress queue that is used to reach the destination. The fc-name also defines the encoded forwarding class of the encapsulation.

The FC configuration also affects how mirrored packets are treated at the ingress queuing point on the line cards. One ingress queue is used per mirror destination (service) and that is an expedited queue if the configured FC is expedited (one of nc, h1, ef or h2). The ingress mirror queues have no CIR, but a line-rate PIR.

The no form of this command reverts the mirror-dest service ID forwarding class to the default forwarding class.

Default

The best effort (be) forwarding class is associated with the mirror-dest service ID.

Parameters

fc-name

The name of the forwarding class with which to associate mirrored service traffic. The forwarding class name must already be defined within the system. If the fc-name does not exist, an error is returned and the fc command has no effect. If the fc-name does exist, the forwarding class associated with fc-name overrides the default forwarding class.

Description

This command indicates 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. fc Request Packet and Behavior summarizes this behavior.

Default

Full Context

configure qos post-policer-mapping fc

Description

This command specifies the forwarding class and profile state of an egress policed packet that is to be mapped to another forwarding class and profile, where the profile state is that of the resulting profile after the packet has been processed by the egress policer.

The new forwarding class and profile state is configured using the maps-to command.

The traffic remarking is based on the marking configured for the forwarding class and profile of the traffic after being policed but before it is remapped.

The no form of this command deletes the forwarding class and profile remapping statement, including the maps-to command.

Parameters

fc-name

Specifies one of the eight forwarding classes supported by the system.

Values

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

profile

Specifies one of the egress packet profile states.

Values

exceed, in, inplus, out

Context

[Tree] (config>qos>sap-ingress fc)

Full Context

configure qos sap-ingress fc

Description

The fc command creates a class or subclass instance of the forwarding class fc-name. When the fc-name is created, classification actions can be applied and the subclass can be used in match classification criteria. Attempting to use an undefined subclass in a classification command will result in an execution error and the command will fail.

The no form of this command removes all the explicit queue mappings for fc-name forwarding types. The queue mappings revert to the default queues for fc-name. To successfully remove a subclass, all associations with the subclass in the classification commands within the policy must first be removed or diverted to another forwarding class or subclass.

Parameters

fc-name

The parameter subclass-name is optional and must be defined using a dot separated notation with a preceding valid system-wide forwarding class name. Creating a subclass follows normal naming conventions. Up to sixteen ASCII characters may be used. If the same sub-name is used with two or more forwarding class names, each is considered a different instance of subclass. A subclass must always be specified with its preceding forwarding class name. When a forwarding class is created or specified without the optional subclass, the parent forwarding class is assumed.

Within the SAP ingress QoS policy, up to 56 subclasses may be created. Each of the 56 subclasses may be created within any of the eight parental forwarding classes. When the limit of 56 is reached, any further subclass creations will fail and the subclass will not exist.

Successfully creating a subclass places the CLI within the context of the subclass for further subclass parameter definitions. Within the subclass context, commands may be executed that define subclass priority (within the parent forwarding class queue mapping), subclass color aware profile settings, subclass in-profile and out-of-profile precedence or DSCP markings.

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 (.). If subclass-name does not exist in the context of fc-name, an error will occur. If subclass-name is removed using the no fc fc-name.subclass-name force command, the default-fc command will automatically drop the subclass-name and only use fc-name (the parent forwarding class for the subclass) as the forwarding class.

Values

fc:	class[.subclass]
		class: be, l2, af, l1, h2, ef, h1, nc
		subclass: 29 characters max

Full Context

configure qos sap-egress fc

Description

The fc fc-name node within the SAP egress QoS policy is used to contain the explicitly defined queue mapping and dot1p marking commands for fc-name. When the mapping for fc-name points to the default queue and the dot1p marking is not defined, the node for fc-name is not displayed in the show configuration or save configuration output unless the detail option is specified.

The no form of this command removes the explicit queue mapping and dot1p marking commands for fc-name. The queue mapping reverts to the default queue for fc-name and the dot1p marking (if appropriate) uses the default of 0.

Default

no fc

Parameters

fc-name

This parameter specifies that the forwarding class queue mapping or dot1p marking is to be edited. The value given for fc-name must be one of the predefined forwarding classes in the system.

Parameters

fc-name

A valid forwarding class must be specified as fc-name when the fc command is executed. When the fc fc-name command is successfully executed, the system will enter the specified forwarding class context where the queue queue-id command may be executed.

[Tree] (cfg>qos>qgrps>egr>qgrp fc)

Full Context

configure qos queue-group-templates egress queue-group fc

Description

The fc command is used to enter the forwarding class mapping context for the given fc-name. Each forwarding class has a default mapping depending on the egress queue group template. The system-created policer-output-queue template contains queues 1 and 2 by default with queue 1 being best-effort and queue 2 expedited. Forwarding classes be, l1, af and l2 all map to queue 1 by default. Forwarding classes h1, ef, h2 and nc all map to queue 2 by default. More queues may be created within the policer-output-queues template and the default forwarding classes may be changed to any defined queue within the template.

When all other user-defined egress queue group templates are created, only queue 1 (best-effort) exists and all forwarding classes are mapped to that queue. Other queues may be created and the forwarding classes may be changed to any defined queue within the template.

Besides the default mappings within the templates, the egress queue group template forwarding class queue mappings operate the same as the forwarding class mappings in a sap-egress QoS policy.

The template forwarding class mappings are the default mechanism for mapping egress policed traffic to a queue within an egress port queue group associated with the template. If a queue-id is explicitly specified in the QoS policy forwarding class policer mapping, and that queue exists within the queue group, the template forwarding class mapping is ignored.

On the 7450 ESS and 7750 SR, egress policed subscriber traffic works in a slightly different way. The subscriber and subscriber host support destination and organization strings are used to identify the egress port queue group. In this instance, the forwarding class mappings are always used and any queue overrides in the QoS policy are ignored. If neither string exists for the subscriber host, the egress queue group queue-id can be derived from either the QoS policy policer mapping or the template forwarding class queue mappings.

The no form of this command is used to return the specified forwarding class to its default template queue mapping.

Parameters

fc-name

A valid forwarding class must be specified as fc-name when the fc command is executed. When the fc fc-name command is successfully executed, the system will enter the specified forwarding class context where the queue queue-id command may be executed.

Values

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

Description

This command creates individual counters for the specified FCs without regard for profile. All countable packets that match a configured FC, regardless of profile, will be included in this counter.

A differential is performed when this command is re-entered. Omitted FCs will stop counting, newly added FCs will start counting, and unchanged FCs will continue to count.

Up to eight FCs may be specified. An FC that is specified as part of this command for this specific context cannot be specified as a profile-aware FC using the fc-in-profile command under the same context.

The no form of this command removes all previously defined FCs and stops counting for those FCs.

Default

no fc

Parameters

fc-name

Specifies the name of the FC for which to create an individual profile-unaware counter. A maximum of eight fc-names can be specified in a single statement. In order for the counter to be used, the config>oam-pm>session> ethernet>priority command must be configured with a numerical value representing the FC name (7 = NC, 6 = H1, 5 = EF, 4 = H2, 3 = L1, 2 = AF, 1 = L2, 0 = BE), and the config>oam-pm>session>ethernet>lmm>enable-fc-collection command must be enabled.

Description

This command associates a forwarding-class and optionally priority with the routes matched by a route policy entry. The command takes effect when the action of the route policy entry is accept, next-entry, or next-policy. It has no effect except in route policies applied as VRF import policies, BGP import policies, or RIP import policies.

The no form of this command removes the QoS association of the routes matched by the route policy entry.

Default

no fc

Parameters

fc

Specify the name of one of the predefined forwarding classes in the system.

Values

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

Default

none (no QoS information is associated with matched routes)

priority {low | high}

This parameter associates an enqueuing priority with routes matched by the policy entry. Specifying a priority is optional.

Values

high — 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. After the packet is placed in a buffer on the ingress queue, the significance of the enqueuing priority is lost.

low — 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. After the packet is placed in a buffer on the ingress queue, the significance of the enqueuing priority is lost.

configure isa video-group watermark bandwidth fcc

Description

This command sets the watermark to trigger the SNMP trap if the FCC bandwidth or session exceeds the configured percentage. The bandwidth is the available egress bandwidth of the ISA. The SNMP trap is cleared when the consumption is lowered by 10%. For example, if the system resource of the available bandwidth is 10 Gb/s and the watermark is configured to be 90%, the SNMP trap is raised as the bandwidth exceeds 9 Gb/s (90% of 10 Gb/s). The SNMP trap is cleared when the bandwidth drops below 8.1 Gb/s (10% of 9 Gb/s = 0.9 Gb/s, and 9 Gb/s - 0.9 Gb/s = 8.1 Gb/s). The default value of the watermark is set at 90% of the system resources for both bandwidth and session.

Description

This command enables the Fast Channel Change (FCC) server and sets the mode to send the FCC unicast stream.

The mode indicates how the FCC server will send information to the client. When burst is specified, the FCC server will send the channel at a nominally faster rate than the channel was received based on the applicable fcc-burst setting. When dent is specified, the FCC server will selectively discard frames from the original stream based on the applicable dent-threshold setting. If no mode is specified, burst is the default mode.

The no form of the command disables the FCC server at that context and subordinate contexts.

Default

no fcc-server

Parameters

mode burst

Sets the mode of the FCC server to burst when sending the channel to the FCC client.

mode dent

Sets the mode of the FCC server to dent when sending the channel to the FCC client.

mode hybrid

Combines the burst and dent modes.

Full Context

configure port otu fec

Description

This command enables the Forwarding Error Correction (FEC) encoder/decoder and specifies the FEC encoder/decoder mode to use when enabled.

The following rules must be followed:

• The port’s OTU must be enabled to set or change the FEC mode.

• The port must be shut down before changing the FEC mode.

• The sf-sd-method must be changed to BIP8 before setting the FEC mode to disabled.

Note that FEC cannot be disabled on OTU3 encapsulated OC768 or 40-Gigabit Ethernet by the no fec command. Therefore, the default depends on the port type. The default for OTU3 encapsulated OC768 or 40-Gigabit Ethernet is fec enhanced.

The no form of this command disables FEC encoder and decoder.

Default

no fec

Parameters

enhanced

Enables the FEC encoder and decoder with a proprietary enhanced FEC algorithm.

g709

Enables the FEC encoder and decoder with the standard G.709 FEC algorithm.

Context

[Tree] (config>router>ldp>session-params>peer fec-limit)

Full Context

configure router ldp session-parameters peer fec-limit

Description

This command configures a limit on the number of FECs which an LSR will accept from a given peer and add into the LDP label database. The limit applies to the aggregate count of all FEC types including service FEC. Once the limit is reached, any FEC received will be released back to the peer. This behavior is different from the per-peer import policy which will still accept the FEC into the label database but will not resolve it.

When the FEC limit for a peer is reached, the LSR performs the following actions:

1. Generates a trap and a syslog message.

2. Generates a LDP notification message with the LSR overload status TLV, for each LDP FEC type including service FEC, to this peer only if this peer advertised support for the LSR overload sub-TLV via the LSR Overload Protection Capability TLV at session initialization.

3. Releases, with LDP Status Code of "No_Label_Resources", any new FEC, including service FEC, from this peer which exceeds the limit.

If a legitimate FEC is released back to a peer, while the FEC limit was exceeded, the user must have a means to replay that FEC back to the router LSR once the condition clears. This is done automatically if the peer is an SR OS-based router and supports the LDP overload status TLV ( SR OS 11.0R5 and higher). Third-party peer implementations must support the LDP overload status TLV or provide a manual command to replay the FEC.

The threshold option allows to set a threshold value when a trap and an syslog message are generated as a warning to the user in addition to when the limit is reached. The default value for the threshold when not configured is 90%.

The log-only option causes a trap and syslog message to be generated when reaching the threshold and limit. However, LDP labels are not released back to the peer.

If the user decreases the limit value such that it is lower than the current number of FECs accepted from the peer, the LDP LSR raises the trap for exceeding the limit. In addition, it will set overload for peers which signaled support for LDP overload protection capability TLV. However, no existing resolved FECs from the peer which does not support the overload protection capability TLV should be de-programmed or released.

A different trap is released when crossing the threshold in the upward direction, when reaching the FEC limit, and when crossing the threshold in the downward direction. However the same trap will not be generated more often than 2 minutes apart if the number of FECs oscillates around the threshold or the FEC limit.

Default

no fec-limit

Parameters

limit

Specifies the aggregate count of FECs of all types which can be accepted from this LDP peer.

log-only

Specifies that only a trap and syslog message are generated when reaching the threshold and limit. However, LDP labels are not released back to the peer.

percentage

Specifies the threshold value (as a percentage) that triggers a warning syslog message and trap to be sent.

configure router ldp fec-originate

Description

This command defines a way to originate a FEC (with a swap action) for which the LSR is not egress, or to originate a FEC (with a pop action) for which the LSR is egress.

Parameters

ip-prefix/mask

Specifies information for the specified IP prefix and mask length.

Values

ipv4-prefix - a.b.c.d
ipv4-prefix-le - [0..32]
ipv6-prefix	x:x:x:x:x:x:x:x (eight 16-bit pieces)
	x:x:x:x:x:x:d.d.d.d
	x - [0..FFFF]H
	d - [0..255]D
	ipv6-prefix-le - [0..128]

next-hop

Specifies the IP address of the next hop of the prefix.

advertised-label

Specifies the label advertised to the upstream peer. If not configured, then the label advertised should be from the label pool. If the configured static label is not available then the IP prefix is not advertised.

out-label

Specifies the LSR to swap the label. If configured, then the LSR should swap the label with the configured swap-label. If not configured, then the default action is pop if the next-hop parameter is not defined.

The next-hop, advertised-label, swap-label parameters are all optional. If next-hop is configured but no swap label specified, it will be a swap with label 3, such as, pop and forward to the next-hop. If the next-hop and swap-label are configured, then it is a regular swap. If no parameters are specified, a pop and route is performed.

Values

16 to 1048575

in-label

Specifies the number of labels to send to the peer associated with this FEC.

Values

32 to 1023

pop

Specifies to pop the label and transmit without the label.

interface interface-name

Specifies the name of the interface the label for the originated FEC is swapped to. For an unnumbered interface, this parameter is mandatory since there is no address for the next-hop. For a numbered interface, it is optional.

Full Context

configure router ldp egress-statistics fec-prefix

Description

This command configures statistics in the egress data path at the ingress LER or LSR for an LDP FEC. The user must execute the no shutdown command for this command to effectively enable statistics. The egress data path counters will be updated for both originating and transit packets. Originating packets may be service packets or IP user and control packets forwarded over the LDP LSP when used as an IGP shortcut. Transit packets of the FEC which are label switched on this node.

When ECMP is enabled and multiple paths exist for a FEC, the same set of counters are updated for each packet forwarded over any of the NHLFEs associated with this FEC and for as long as this FEC is active.

The statistics can be enabled on prefix FECs imported from both LDP neighbors and T-LDP neighbors (LDP over RSVP). LDP sets up egress statistics collection for the LDP tunnels whose FECs match the exact prefix specified in this command. Service FECs, that is, FEC 128 and FEC 129, are not valid. LDP FEC egress statistics are collected at the Penultimate-Popping Hop (PHP) node for a LDP FEC using an implicit null egress label.

The no form of this command disables the statistics in the egress data path and removes the accounting policy association from the LDP FEC.

Parameters

ip-prefix

Specifies the IP address representing the FEC.

Values

IPv4 prefix:	a.b.c.d	a, b, c, d - 0 to 255; decimal
IPv6 prefix:	x:x:x:x:x:x:x:x (eight 16-bit pieces)	x - 0 to FFFF; hexadecimal

Context

[Tree] (config>log file-id)

Full Context

configure log file-id

Description

This command creates the context to configure a file policy that is used as the destination for an event log or billing (accounting) file.

This command defines the file location and characteristics that are to be used as the destination for a log event message stream or accounting/billing information. The file defined in this context is subsequently specified in the to command under log-id or accounting-policy to direct specific logging or billing source streams to the file destination.

A file policy can only be assigned to either one log-id or one accounting-policy. It cannot be reused for multiple instances. A file policy and associated file definition must exist for each log and billing file that must be stored in the file system.

A file is created when the file policy defined in this command is selected as the destination type for a specific log or accounting record. Log files are collected in a ‟log” directory. Accounting files are collected in an ‟act” directory.

The file names for a log are created by the system as summarized in Log File Names.

Where:

• ll is the log-id

• aa is the accounting policy-id

• ff is the file-id

• The timestamp is the actual timestamp when the file is created. The format for the timestamp is yyyymmdd-hhmmss where:

  • yyyy is the year (for example, 2006)

  • mm is the month number (for example, 12 for December)

  • dd is the day of the month (for example, 03 for the 3rd of the month)

  • hh is the hour of the day in 24 hour format (for example, 04 for 4 a.m.)

  • mm is the minutes (for example, 30 for 30 minutes past the hour)

  • ss is the number of seconds (for example, 14 for 14 seconds)

• The accounting file is compressed and has a gz extension.

When initialized, each file contains:

• The log-id description.

• The time the file was opened.

• The reason the file was created.

• If the event log file was closed properly, the sequence number of the last event stored on the log is recorded.

If the process of writing to a log file fails (for example, the compact flash card is full) and if a backup location is not specified or fails, the log file will not become operational even if the compact flash card is replaced. Enter either a clear log command or a shutdown/no shutdown command to reinitialize the file.

If the primary location fails (for example, the compact flash card fills up during the write process), a trap is sent and logging continues to the specified backup location. This can result in truncated files in different locations.

The no form of this command removes the file policy from the configuration. A file policy can only be removed from the configuration if the policy is not the designated output for a log destination. The actual log or accounting file remain on the file system when a file policy is deleted.

Parameters

file-id

The file identification number for the file policy, expressed as a decimal integer.

Values

1 to 99

name file-policy-name

Configures an optional file policy name, up to 64 characters, that can be used to refer to the file policy after it is created. If the name begins with a numerical digit (from 1 to 9), the name is a number from 1 to 99.

configure mirror mirror-dest pcap file-url

Description

This command specifies a file URL for the FTP or TFTP server, including the filename for packet capture transfer. After the file URL is entered, the system attempts to establish a connection and creates a file using the filename specified. The command prompt displays an error and rejects the file URL if the session establishment fails, if write privilege to remote server fails, or if the session experiences a sudden termination. If the FTP or TFTP server is unreachable, the command prompt is halted for further input until the retires are timed out after 24 seconds (after four attempts of about six seconds each). This command overwrites any file on the FTP or TFTP server with the same filename.

The no form of this command removes the file-url instance and stops the packet capture and file transfer session.

Description

This command associates an IP filter policy with an ingress or egress Service Access Point (SAP) or IP interface. An IP filter policy can be associated with spoke SDPs. Filter policies control the forwarding and dropping of packets based on IP or MAC matching criteria.

The filter command is used to associate a filter policy with a specified ip-filter-id with an ingress or egress SAP. The ip-filter-id must already be defined before the filter command is executed. If the filter policy does not exist, the operation fails and an error message returned.

In general, filters applied to SAPs (ingress or egress) apply to all packets on the SAP. One exception is non-IP packets are not applied to IP match criteria, so the default action in the filter policy applies to these packets.

The no form of this command removes any configured filter ID association with the SAP or IP interface. The filter ID itself is not removed from the system unless the scope of the created filter is set to local. To avoid deletion of the filter ID and only break the association with the service object, use scope command within the filter definition to change the scope to local or global. The default scope of a filter is local.

Parameters

ip ip-filter-id

Specifies IP filter policy. The filter ID must already exist within the created IP filters.

Description

This command associates a filter policy with an ingress or egress Service Access Point (SAP). Filter policies control the forwarding and dropping of packets based on the matching criteria. MAC filters are only allowed on Epipe and Virtual Private LAN Service (VPLS) SAPs.

The filter command is used to associate a filter policy with a specified ip-filter-id or ipv6-filter-id (7750 SR) with an ingress or egress SAP. The filter policy must already be defined before the filter command is executed. If the filter policy does not exist, the operation fails and an error message returned.

In general, filters applied to SAPs (ingress or egress) apply to all packets on the SAP. One exception is non-IP packets are not applied to the match criteria, so the default action in the filter policy applies to these packets.

The no form of this command removes any configured filter ID association with the SAP. The filter ID itself is not removed from the system unless the scope of the created filter is set to local. To avoid deletion of the filter ID and only break the association with the service object, use scope command within the filter definition to change the scope to local or global. The default scope of a filter is local.

Parameters

ip ip-filter-id

Specifies the ID for the IP filter policy and corresponds to a previously created IP filter policy in the config>filter>ip-filter context.

Values

Description

This command associates an IP filter policy or MAC filter policy with an ingress or egress Service Access Point (SAP) or IP interface.

Filter policies control the forwarding and dropping of packets based on IP or MAC matching criteria. There are two types of filter policies: IP and MAC. Only one type may be applied to a SAP at a time.

The filter command is used to associate a filter policy with a specified filter ID with an ingress or egress SAP. The filter ID must already be defined before the filter command is executed. If the filter policy does not exist, the operation will fail and an error message returned.

In general, filters applied to SAPs (ingress or egress) apply to all packets on the SAP. One exception is non-IP packets are not applied to IP match criteria, so the default action in the filter policy applies to these packets.

This command is only supported in 'classic' configuration-mode (configure system management-interface configuration-mode classic).

The no form of this command removes any configured filter ID association with the SAP or IP interface. The filter ID itself is not removed from the system unless the scope of the created filter is set to local. To avoid deletion of the filter ID and only break the association with the service object, use scope command within the filter definition to change the scope to local or global. The default scope of a filter is local.

Parameters

ip ip-filter-id

Specifies IP filter policy. The filter ID must already exist within the created IP filters.

Values
