Description
This command defines the administrative Peak Information Rate (PIR) and the administrative
Committed Information Rate (CIR) parameters for the queue. 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 percentage at which the system prioritizes the queue over other queues
competing for the same bandwidth. For , the CIR also defines the rate that considered in-profile by
the system.
The rate command can be executed at anytime, altering the PIR and CIR rates for all queues
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 (100, 0).
Parameters
cir percent — Defines the percentage of the guaranteed rate allowed for the queue. When the rate
command is executed, . When the rate command has not been executed, the default is assumed.
Fractional values are not allowed and must be given as a positive integer.
The actual rate is dependent on the queue's adaptation-rule parameters and the actual hardware where
the queue is provisioned.
Values
Default

constraint used when deriving the operational CIR for the queue. When the cir parameter
is not specified, the default constraint applies.
max — The max (maximum) option is mutually exclusive with the min and closest
options. When max is defined, the operational PIR for the queue will be equal to or less
than the administrative rate specified using the rate command.
min — The min (minimum) option is mutually exclusive with the max and closest
options. When min is defined, the operational PIR for the queue will be equal to or greater
than the administrative rate specified using the rate command.
closest — The closest parameter is mutually exclusive with the min and max parameter.
When closest is defined, the operational PIR for the queue will be the rate closest to the
rate specified using the rate command.
