Description
This command configures the time to wait for a BFD to come up in seconds. This timer is applicable to SR-TE LSPs, including auto-LSPs and PCE-initiated LSPs, as well as RSVP-TE LSPs. In case of SR-TE LSPs, this timer takes effect if BFD does not come up, or BFD goes from up to down. The timer is started when BFD is first enabled on a path or BFD transitions from up to down. When the timer expires if BFD is not yet come up, then the path is torn down by removing it from the TTM and the IOM and the retry timer is started.
In case of RSVP-TE LSPs, the timer controls the following:
-
a path undergoing MBB when BFD is up on the original path
-
the initial administrative enable of an LSP
-
signaling retry of non-standby secondary paths
The no form of this command sets the timer to its default value.
Default

Description
This command configures the time interval, in seconds, that is used to wait for a BFD session to come up.
This command is triggered when a spoke-SDP is first administratively enabled and a VCCV BFD session transitions from up to down. The command is required to allow time for BFD sessions to come up, and for BFD to settle before selecting the active spoke-SDP to use in a redundant set. In the case where a VCCV BFD session is bouncing, the timer prevents excessive flapping of the operational state of a spoke-SDP.
The no form of this command disables the timer.
Default

configure redundancy multi-chassis peer warm-standby
Description
This command enables Oversubscribed Multi-Chassis Redundancy (OMCR) model where subscriber hosts are synchronized between the two chassis only in the control plane and are kept there (as part of the Multi-Chassis Synchronization (MCS) state) until the switchover occurs. Link or nodal failure will trigger the switchover at which point the subscriber hosts are being fully instantiated in the control and the forwarding plane. This approach allows oversubscription of the resources in the central standby (or protecting) node that is backing-up several active nodes. The total number of protected subscribers in the OMCR cluster exceeds the forwarding capacity of the protecting node. This is achievable by not fully occupying the resources for the subscriber hosts until the failure occurs.
The restoration times depend on the amount of the subscriber hosts that are affected by the switchover and it is related to the time needed for the full instantiation of the subscribers in the forwarding plane.
Although this command is configured on a peer level, the warm-standby property is a nodal characteristic. In other words, mixing of N:1 and 1:1 (hot standby) mode in the central standby node is not supported. Consequently all peers on the central standby node must be configured for warm-standby (N:1), or all peers must be configured for hot-standby (1:1) by omitting the warm-standby keyword from the configuration.
The peer of the central backup node is not aware of the redundancy model supported. In in other words, the peer of the central-backup node does not know whether it peers with a warm-standby peer or host-standby-peer.

Full Context
configure aaa diameter node peer watchdog-timer
Description
Watchdog messages are used to verify liveliness of a Diameter peer. A single watchdog message is sent to a peer in case that no traffic is received from it within a configured watchdog-timer. This watchdog request message solicits a watchdog answer message from the peer. If no traffic (watchdog answer or otherwise) is received from the peer in response to watchdog request while the watchdog timer is running, the peer ise put in suspicious state and a peer failover routine is triggered.
The peer closes after it has been in suspicious mode for the duration of one more watchdog-timer interval without receiving any traffic from it.
After the peer is recovered, it takes three successful exchanges of diameter watchdog messages (DWR/DWA) for the peer to become used again in Diameter forwarding. This behavior is described in RFC 3539, §3.4.1, Authentication, Authorization and Accounting (AAA) Transport Profile).
This command is not applicable to legacy implementations of Diameter base in the SR OS.
The no form of this command removes the watchdog timer value from the configuration.
Default
watchdog-timer 30
Parameters
- seconds
-
Specifies the device watchdog timer, in seconds, used on all connections by this peer.

Description
This command creates a context to configure an event set threshold within a lag-port-down priority control event. The weight-down command defines a sub-node within the lag-port-down event and is uniquely identified with the lag-ports-down-weight parameter. Each weight-down node within the same lag-port-down event node must have a unique lag-ports-down-weight value. Each weight-down node has its own priority command that takes effect whenever that node represents the current threshold. A single LAG can use either weight-based (weight-down) or port-based (number-down) thresholds. The weight-based thresholds are required for correct operation on mixed port-speed LAGs, but can be used for non mixed port-speed LAGs as well. The weights for the weight-down node are normalized from the hash-weight values of the LAG member ports to fit a 1 to 64 range for 64-link capable LAGs and a 1 to 32 range for other LAGs.
The total number of sub-nodes (uniquely identified by the lag-ports-down-weight parameter) allowed in the system is 2048.
A weight-down node is not required for each possible number of ports that could be down. The active threshold is always the closest lower threshold.
The no form of the command deletes the event set threshold. The threshold may be removed at any time. If the removed threshold is the current active threshold, the event set thresholds must be re-evaluated after removal.
Default
no weight-down
Parameters
- lag-ports-down-weight
-
The total weight of LAG ports down to create a set event threshold. This is the active threshold when the weight of down ports in the LAG equals or exceeds lag-ports-down-weight, but does not equal or exceed the next highest configured lag-ports-down-weight.

This command enables the processing of the EVPN link bandwidth extended community when installing an ECMP set for an EVPN IP-Prefix route in the VPRN route-table.
Flows to an IP Prefix received with a weight and a zero ESI value are sprayed according to the weight. If the EVPN IP Prefix route received with the weight has a non-zero ESI, the weight is divided into the number of PEs attached to the Ethernet Segment (and rounded up if the result is not an integer).
This command also enables the weighted ECMP functionality for BGP CEs that are configured with an evpn-link-bandwidth add-to-received-bgp weight.

Description
This command enables weighted load-balancing for IS-IS, OSPF, and static ECMP routes in the VPRN instance. Weighted ECMP can be performed when all next hops are configured with non-zero load-balancing weights. Weighted ECMP support for IS-IS, OSPF, and static ECMP routes applies to both IPv4 and IPv6.
The no form of this command restores regular ECMP spraying of packets to IS-IS, OSPF and static route destinations.
Default
no weighted-ecmp
Parameters
- strict
-
Enables strict enforcement for a load balancing weight to be configured on each interface withing a wECMP interface bundle before the interface is taken into wECMP operation. However, when strict enforcement is not enabled, then, when load-balancing-weight is not configured on one or more interfaces within the wECMP interface bundle, the wECMP load-balancing falls back to classic ECMP operation and equally share the traffic load across the ECMP interface bundle. A special case is when none of the available paths or next-hops have a load balancing weight associated. Then, the load balancing falls back to classic ECMP.
Strict load balancing is only applied on IS-IS, OSPF, and static route entries.

Static route prefix resolved to an indirect next-hop, which itself is resolved to a set of equal-metric MPLS LSPs in TTM. The user can allow automatic selection or specify the names of the equal-metric MPLS LSPs in TTM to be used in the ECMP set.
-
Static route prefix resolved to an indirect next-hop, which is resolved to IGP shortcuts in RTM.
-
BGP prefix with a BGP next-hop resolved to a static route, which resolves to a set of tunnel next-hops toward an indirect next-hop in RTM or TTM.
-
BGP prefix resolving to another BGP prefix, whose next-hop is resolved to a set of ECMP tunnel next-hops with a static route in RTM or TTM or to IGP shortcuts in RTM.
IGP computes the normalized weight for each prefix tunnel next-hop. IGP updates the route in RTM with the set of tunnel next-hops and normalized weights. RTM downloads the information to IOM for inclusion in the FIB.
If one or more LSPs in the ECMP set of a prefix do not have a weight configured, the regular ECMP spraying for the prefix will be performed.
The weight assigned to an LSP impacts only the forwarding decision, not the routing decision. In other words, it does not change the selection of the set of ECMP tunnel next-hops of a prefix when more next-hops exist than the value of the router ecmp option. Once the set of tunnel next-hops is selected, the LSP weight is used to modulate the amount of packets forwarded over each next-hop. It also does not change the hash routine, but only the spraying of the flows over the tunnel next-hops is modified to reflect the normalized weight of each tunnel next-hop.
The no form of this command resumes regular ECMP spraying of packets of IGP, BGP, and static route prefixes over MPLS LSP.
Default
no weighted-ecmp
Parameters
- strict
-
Enables strict enforcement for a load balancing weight to be configured on each interface withing a wECMP interface bundle before the interface is taken into wECMP operation. However, when strict enforcement is not enabled, then, when load-balancing-weight is not configured on one or more interfaces within the wECMP interface bundle, the wECMP load-balancing falls back to classic ECMP operation and equally share the traffic load across the ECMP interface bundle. A special case is when none of the available paths or next-hops have a load balancing weight associated. Then, the load balancing falls back to classic ECMP.
Strict load balancing is only applied on IS-IS, OSPF, and static route entries.

Description
This command specifies the integrity of the sample window. A percentage value that suggests the measurement has enough samples (integrity) to be considered representative for that sample window. The configured percentage considers the interval of the test PDUs, and the length of the sample window to determine the number of packets required in the sample.
(((window-integrity %) x (sample-window length (s) x pps per test (interval)).
Ensure that the percentage and the combination of sample window and packet per second per test interval produces the desired results.
If the number of samples in the sample window are equal to or greater than the computed number of required samples, then the value has integrity and the suspect flag is set to false for that streamed result.
If the count is less than the computed number of required samples, then the suspect flag is set to true for that streamed result.
Regardless of the integrity, the average values are streamed. It is up to the higher level systems to interrogate the suspect flag and determine if the value that is set should be used, discarded, or reported separately.
The no form of this command reverts to the default.

Description
This command determines whether the aggregate sample window is integral based on the number of samples received from the sample window, comparing the number of samples to the percentage configured.
The configured percentage translates to a required sample window count that must be included in the aggregate sample window. The range is from 0 to 100. The number of samples is computed as follows:
(window-integrity (%)) x (((aggregate-sample-window length (s)) / (sample-window length (s)))
For an aggregate sample window that does not reach the integrity, the value is not considered as representative and is used for threshold comparison.
If the number of samples in the aggregate sample window are equal to or greater than the computed number of required samples, the sample window has integrity and the aggregate sample window result is compared to configured sample window thresholds.
If the count is less than the computed number of required samples, the aggregate sample window does not have integrity and the aggregate sample window results are compared to configured sample window thresholds.
If this parameter is not configured, integrity checking is disabled and all results are compared to the configured thresholds.
The no form of this command disables integrity checking.
Default

Description
This command creates a WLAN GW group that contains a set of ISAs to be used in WLAN-GW functionality. A WLAN-GW group can also be used where a NAT group is expected. The WLAN-GW group ID shares the same number space with the NAT group.
At most, one WLAN-GW group may be configured.
The optional redundancy parameter determines the provisioning and redundancy mode.
-
IOM mode
A whole IOM is added to the group. The IOM must be fully provisioned with BB ISA modules. In IOM mode, when a single ISA fails, the entire IOM is considered to have failed and all subscribers are recovered on a backup IOM.
-
ISA mode
BB ISA modules are added separately with no restriction put on other MDAs in the IOM. When a single ISA fails, a backup ISA will try to recover as many subscribers as possible but may run out of resources (for example, queues, policers, host entries) during the recovery process. It is recommended to pair ISAs with MDAs and services that do not consume many IOM resources.
The no form of this command removes the group.
Parameters
- group-id

configure port aps working-circuit
Description
This command configures a physical port that will act as the working circuit for this APS group. The working circuit port must contain only the default configuration and cannot be part of another APS group. The working circuit must be created before the protection circuit.
When a port is a working circuit of an APS group, the configuration available under config>port port-id context (including submenus) is not allowed for that port unless it is a part of the noted exceptions.
When a port is being configured as a working circuit of an APS group, all common configuration as described above and all service configurations related to the APS port is operationally inherited by the working circuit from the aps- group-id. If the working circuit cannot inherit that configuration, for example, due to resource limitations, the configuration attempt fails and an error is returned to the user.
Before a working circuit can be removed from an APS group, the working circuit port must be shutdown. The inherited configuration for the circuit and APS operational commands for that circuit are not preserved when the circuit is removed from the APS group.
Note that all configurations for aps-group-id under the config>port context and its submenus and all configuration for services that use this aps- group-id is preserved as a non-activated configuration since the APS group no longer has any physical circuits assigned.
The no form of this command removes the working-circuit. The working circuit can only be removed from the configuration after the protect circuit has been removed.

Modifying Hold-Down Timer Values
Note that for APS configurations, the config>port>sonet-sdh hold-time down and config>port>sonet-sdh hold-time up default values are 100 ms and 500 ms respectively. But, if there is a large difference in the transmission delay between the APS working () and protect line ( config>port>aps protect-circuit), it is highly recommended that you increase the default timer on the working line accordingly with the transmission delay present on the protect line.
The following output shows an example of the timers on POS interfaces.

configure qos sap-egress queue wred-queue
Description
This command allows the configuration of WRED per queue with the following options:
-
Native hardware WRED
This uses the hardware per queue WRED capabilities of FP3- and higher-based hardware and is configured with the native keyword.
-
Pool per queue WRED
This implements each queue in its own pool and uses the WRED capabilities of the pool to provide WRED per queue. This is configured with the pool-per-queue keyword.
Native Hardware WRED
When the wred-queue mode native command is configured, the queue uses the WRED capabilities of FP3- and higher-based hardware. In this case, the out-of-profile and exceed-profile traffic map to the low and exceed WRED slopes specified within the slope policy, and the inplus-profile and in-profile traffic uses the MBS drop tail; this requires the slope-usage to be configured as exceed-low. The instantaneous queue depth is compared against the low and exceed slopes so the time average factor in the slope policy is ignored.
When a policy is not explicitly defined, the default slope policy is used.
When native mode is enabled for a queue, the pool and drop-tail commands are ignored; traffic mapped to a slope that is shut down will use the MBS drop tail.
This is only supported on FP3 hardware.
The no form of this command restores the queue default congestion control behavior to the queue.
Pool-per-queue WRED
When the wred-queue mode pool-per-queue command is defined and the queue ID is created, a buffer pool is created specifically for the queue and the queue obtains all buffers from that pool. The size of the pool is the same as the size of the queue. In this manner, the WRED slopes that operate based on the pool’s buffer utilization are also reacting to the congestion depth of the queue.
The size of the buffer pool is dictated by the queue’s MBS parameter. The size of the reserved CBS portion of the buffer pool is dictated by the queue’s CBS parameter. The provisioning characteristics of the mbs and cbs commands are not changed.
In the case where this is applied with WRED queue support shutdown (config>card>fp>egress>wred-queue-control>shutdown), the queue will continue to map to its default pool. If the no shutdown command is executed in the wred-queue-control context, the queue is automatically moved to its own WRED pool.
Each pool created for a queue using the wred-queue command shares buffers with all other wred-queue enabled queues on the same forwarding plane. The WRED pool buffer management behavior is defined within the config>card>fp>egress>wred-queue-control CLI context.
The WRED slopes within the pool are defined by the slope policy associated with the queue. When a policy is not explicitly defined, the default slope policy is used. The slope policy enables, disables, and defines the relative geometry of the highplus, high, low, and exceed WRED slopes in the pool. The policy also specifies the time average factor used by the pool when calculating the weighted average pool depth.
As packets attempt to enter the egress queue, they are associated with the highplus, high, low, or exceed WRED slope based on the packet’s profile. If the packet is inplus-profile, the highplus slope is used. If the packet is in-profile, the high slope is used. If the packet is out-of-profile, the low slope is used. If the packet is exceed-profile, the exceed slope is used. This mapping of packet profile to slope is enabled using the slope-usage default parameter. Each WRED slope performs a probability discard based on the current weighted average pool depth.
When wred-queue is enabled for a SAP egress queue, the queue pool and drop-tail commands are ignored; traffic mapped to a slope that is shut down will use the MBS drop tail.
The resource usage for the WRED queue pool-per-queue per forwarding plane can be seen in the tools dump resource-usage card [ slot-num] fp [fp-number] output under Dynamic Q2 Wred Pools.
The no form of this command restores the generic buffer pool behavior to the queue. The WRED pool is removed from the system. The queue will be moved to the default buffer pool. The queue then uses the default congestion control behavior.
Default
no wred-queue
Parameters
- slope-policy-name
-
Specifies an existing slope policy that is used to override the default WRED slope policy.
- mode
-
Specifies whether the WRED per queue is using the native FP3- and higher-based hardware WRED capabilities or pool per queue.

Description
This command defines how the specified group ID is attached to the scheduler. A WRR group may have one of two attachment states:
-
directly attached to a scheduler class
-
unattached
A WRR group provides a weighted scheduling context for its member queues, collapsing the queues into a single scheduling class.
The following WRR membership restrictions apply:
-
Two groups are supported: WRR-group 1 and WRR-group 2.
-
Up to six of the eight queues can become members of WRR groups (the sum of the membership of both groups cannot exceed six queues). All six queues can be placed in a single WRR group or they can be spread between the two groups.
-
All queues within a group must have contiguous queue IDs.
-
When both groups are configured to have queue members, the queue IDs in group 1 must be lower than the queue IDs in group 2.
The queue queue-id attachment command is used to define WRR group membership.
The no form of the command reverts to the default unattached attachment state for the group ID.
Default
wrr-group group-id unattached
Parameters
- group-id
-
Specifies the WRR group identifier. The group-id parameter is required when executing the wrr-group attachment command.
- sched-class
-
Specifies a direct attachment between the WRR group and one of the six scheduling classes. The sched-class and unattached keywords are mutually exclusive. One of the keywords must be specified when the wrr-group attachment command is executed.
- class-id
-
Specifies the scheduling class associated with this WRR group. The sched-class keyword specifies the attachment between the group ID and one of the six scheduling classes. A value of 1 through 6 must accompany the sched-class keyword representing the WRR group’s attached scheduling class. Only one queue or WRR group can be attached to a given scheduling class. If another queue or a WRR group is currently attached to the specified scheduling class, the wrr-group attachment command fails and the current attachment for the group-id is unchanged.
- unattached
-
Indicates that the group ID is not attached to any scheduling class or WRR group. Queues that are members of the unattached WRR group do not forward any packets. The sched-class and unattached keywords are mutually exclusive. One of the keywords must be specified when the wrr-group attachment command is executed.
