Global Service Configuration Commands
Without this explicit value, the scheduler will assume that an infinite amount of bandwidth is
available and allow all child queues and schedulers to operate at their maximum rates.
The no form of this command returns all queues created with this queue-id by association with the
QoS policy to the default PIR and CIR parameters.
Parameters
pir-rate — The pir parameter accepts a step multiplier value that specifies the multiplier used to
cir cir-rate — The cir parameter accepts a step-multiplier value that specifies the multiplier used to
scheduler-policy

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,
channel or slot. Scheduler policies are defined in the config>qos>scheduler-policy scheduler-policy-
name context.

determine the PIR rate at which the queue will operate. A value of 0 to 100000000 or the
keyword max 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 at 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.

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.
