QoS Commands
rate
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 Com-
mitted 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 over-
subscription factors or available egress bandwidth. The CIR defines the rate at which the system pri-
oritizes 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
pir-rate — Defines the administrative PIR rate, in kilobits, for the queue. When the rate command is
remarking
Syntax remarking
Context config>qos>access-egress
Description This command enables the system to remark egress packets.
The no form of the command disables remarking.

rate command is executed, a avalid 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 0 — 1000000, max
Default

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
1 — 1000000, max
