Parameters pir-rate — The pir parameter accepts a step multiplier value that specifies the multiplier used to
determine the PIR rate at which the queue will operate. A value of 0 to 100000000 or the
keyword max or sum is accepted. Any other value will result in an error without modifying the
current PIR rate.
To calculate the actual PIR rate, the rate described by the queue’s rate is multiplied by the pir-
rate.
The SAP ingress context for PIR is independent of the defined forwarding class (fc) for the
queue. The default pir and definable range is identical for each class. The PIR in effect for a
queue defines the maximum rate ate which the queue will be allowed to forward packets in a
given second, thus shaping the queue’s output.
The PIR parameter for SAP ingress queues do not have a negate (no) function. To return the
queues PIR rate to the default value, that value must be specified as the PIR value.
Values 1 — 100000000, max
Default max
cir cir-rate — The cir parameter accepts a step-multiplier value that specifies the multiplier used to
determine the CIR rate at which the queue will operate. A value of 0 to 250 or the keyword max
is accepted. Any other value will result in an error without modifying the current CIR rate.
To calculate the actual CIR rate, the rate described by the rate pir pir-rate is multiplied by the cir
cir-rate. If the cir is set to max, then the CIR rate is set to infinity.
The SAP ingress context for CIR is dependent on the defined forwarding class (fc) for the queue.
The default CIR and definable range is different for each class. The CIR in effect for a queue
defines both its profile (in or out) marking level as well as the relative importance compared to
other queues for scheduling purposes during congestion periods.
Values 0 — 10000000, max, sum
Default sum

Description This command applies an existing scheduler policy to an ingress or egress scheduler used by SAP
queues associated with this multi-service customer site. The schedulers defined in the scheduler
policy can only be created once the customer site has been appropriately assigned to a chassis port,
