Syntax
rate cir cir-rate [pir pir-rate]
no rate
Context
config>qos>access-egress>queue
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 through the port. 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.
The rate command can be executed at anytime, altering the PIR and CIR rates for all queues
created on the access ports.
The no form of this 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
cir-rate — The cir parameter overrides the default administrative CIR used by the queue. When the rate
command is executed, a valid CIR setting must be explicitly defined. 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
pir-rate — Defines the administrative PIR rate, in kilobits, for the queue. When the rate command is
executed, a PIR setting is optional. When the rate command has not been 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
