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).
Parameters rate max cir 0 — The max default specifies the amount of bandwidth in kilobits per second

The actual PIR rate is dependent on the queue's adaptation-rule parameters and the actual
hardware where the queue is provisioned.

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.
