The network elements (NEs) in a SONET/SDH network constantly monitor the health of the network. When a failure is detected, the network proceeds through a coordinated pre-defined sequence of steps to transfer (or switchover) live traffic to the backup facility (called protection facility.) This is done very quickly to minimize lost traffic.

    Interfaces INTERFACE CONFIGURATION GUIDE RELEASE 15.0.R1 Description The buffer-allocation command defines the amount of buffers that will be set aside for WRED queue buffer pools. Note that the min percentage and max percentage parameters must be set to the same value. The forwarding plane protects against cross application buffer starvation by implementing a hierarchy of buffer pools.

    INTERFACE CONFIGURATION GUIDE Interfaces RELEASE 15.0.R1 Context config>card>fp>egress>wred-queue-control Description This command defines the amount of buffers within the WRED mega-pool that will be set aside for WRED queues operating within their configured CBS thresholds. Note that the min percentage and max percentage parameters must be set to the same value. The forwarding plane protects against WRED queue buffer starvation by setting aside a portion of the buffers within the WRED mega-pool.

  • Page 312

    Interfaces INTERFACE CONFIGURATION GUIDE RELEASE 15.0.R1 Description This command configures WRED slopes within the WRED mega-pool. The WRED slopes in the WRED mega-pool are used when WRED queues are requesting buffers from the mega- pool while they are over their CBS threshold. Once over the CBS threshold, the WRED queue stops receiving buffers from the CBS reserve in the mega-pool and starts competing for buffers in the shared portion of the mega-pool.

    INTERFACE CONFIGURATION GUIDE Interfaces RELEASE 15.0.R1 The no max-rate command returns the policer-control-policy’s parent policer maximum rate to max. Default Parameters rate — Defining a kilobits-per-second value is mutually exclusive with the max parameter. The kilobits-per-second value must be defined as an integer that represents the number of kilobytes that the parent policer will be decremented per second.

  • Page 318

    Interfaces INTERFACE CONFIGURATION GUIDE RELEASE 15.0.R1 Description The mbs-contribution command is used to configure the policy-based burst tolerance for a parent policer instance created when the policy is applied to a SAP or subscriber context. The system uses the parent policer’s min-thresh-separation value, the priority level’s mbs- contribution value and the number of child policers currently attached to the priority level to derive the priority level’s shared-portion and fair-portion of burst tolerance within the local priority level.

  • Page 319

    INTERFACE CONFIGURATION GUIDE Interfaces RELEASE 15.0.R1 This level of fair aggregate burst tolerance is based on the decrement rate of the parent policer’s PIR bucket while the individual fair bursts making up the aggregate are based on each child’s FIR decrement rate. The aggregate fair rate of the priority level is managed by the system with consideration of the current rate of traffic in higher priority levels.

  • Page 320

    Interfaces INTERFACE CONFIGURATION GUIDE RELEASE 15.0.R1 In most cases, lower priority traffic in the policer will be responsible for the greater part of congestion above the parent policer rate. Since this traffic is discarded with a lower threshold, this lowers the effective burst tolerance even while the highest priority traffic is present. Configuring a Priority Level's MBS Contribution Value In the most conservative case, a priority level’s mbs-contribution value may be set to be greater than the sum of child policer’s mbs and one max-size-frame per child policer.

  • Page 321

    INTERFACE CONFIGURATION GUIDE Interfaces RELEASE 15.0.R1 bytes, kilobytes — The bytes keyword is optional and is mutually exclusive with the kilobytes keyword. When specified, size is interpreted as specifying the size of min- thresh-separation in bytes. The kilobytes keyword is optional and is mutually exclusive with the bytes keyword.

  • Page 323

    INTERFACE CONFIGURATION GUIDE Interfaces RELEASE 15.0.R1 One thing to note is that a priority level’s shared-portion of the parent policer’s PIR bucket depth is only necessary to provide some separation between a lower priority’s discard-all threshold and this priority’s discard-unfair threshold. It is expected that the burst tolerance for the unfair packets is relatively minimal since the child policers feeding the parent policer priority level all have some amount of fair burst before entering into an FIR exceed or unfair state.

  • Page 332

    Interfaces INTERFACE CONFIGURATION GUIDE RELEASE 15.0.R1 Stable pool sizing preserves the ability to modify the effective bandwidth used to determine a port’s relative share of the available buffers through the use of the ing-percentage-of-rate and egr-percentage-of-rate commands under the port configuration. Changing the values associated with these commands will cause a reevaluation of buffer distribution and thus a possible resizing of pools on each port within the module.
