executed, the default PIR of max is assumed.
Fractional values are not allowed and must be given as a positive integer.
The actual PIR rate is dependent on the queue's adaptation-rule parameters and the actual hardware
where the queue is provisioned.
Values
Default
cir-rate — The cir parameter overrides the default administrative CIR used by the queue. When the rate
command is executed, a CIR setting is optional. When the rate command has not been executed or the
cir parameter is not explicitly specified, the default CIR (0) is assumed.
Fractional values are not allowed and must be given as a positive integer.
Values
Default
police — Specifies that the out of profile traffic feeding into the physical queue instance should be dropped.
Using this keyword will override the bandwidth specified by the SAP ingress queue's administrative
CIR.

Description
This command defines the administrative Peak Information Rate (PIR) and the administrative Committed
Information Rate (CIR) parameters for the queue. The PIR defines the maximum rate that the queue can
transmit packets out an egress interface (for SAP egress queues). Defining a PIR does not necessarily
guarantee that the queue can transmit at the intended rate. The actual rate sustained by the queue can be
limited by oversubscription factors or available egress bandwidth.
The CIR defines the rate at which the system prioritizes the queue over other queues competing for the same
bandwidth. In-profile packets are preferentially queued by the system at egress and at subsequent next hop
nodes where the packet can traverse. To be properly handled as in- or out-of-profile throughout the network,
the packets must be marked accordingly for profiling at each hop.
The CIR can be used by the queue's parent commands cir-level and cir-weight parameters to define the
amount of bandwidth considered to be committed for the child queue during bandwidth allocation by the
parent scheduler.
The rate command can be executed at anytime, altering the PIR and CIR rates for all queues created through
the association of the SAP egress QoS policy with the queue-id.
The no form of the command returns all queues created with the queue-id by association with the QoS
policy to the default PIR and CIR parameters (max, 0).
Default
rate max cir 0 — The max default specifies the amount of bandwidth in kilobits per second (thousand bits
per second). The max value is mutually exclusive to the pir-rate value.
