QoS Commands
Network Queue QoS Policy Queue Commands
queue
Syntax queue queue-id
Context config>qos>network-queue
Description
This command enables the context to configure a QoS network-queue policy queue.
The FCs are mapped to these queues as per
page
is the lowest priority. Queue carry both the unicast and multicast traffic and no segregation is done.
The hardware port scheduler prioritizes the queue according to the priority for each queue. High pri-
ority traffic should be mapped to high priority FC. Mapping traffic to high priority FC does not neces-
sarily guarantee high priority treatment since the scheduler policy can influence the relative priority
among the queues.
The no form of this command is not supported.
Parameters
queue-id — The queue-id for the queue, expressed as an integer. The queue-id uniquely identifies the
adaptation-rule
8
Syntax adaptation-rule [cir adaptation-rule] [pir adaptation-rule]
no adaptation-rule
Context config>qos>network-queue>queue
Description This command defines the method used by the system to derive the operational CIR and PIR settings
when the queue is provisioned in hardware. For the CIR and PIR parameters individually, the system
attempts to find the best operational rate depending on the defined constraint.
The no form of the command removes any explicitly defined constraints used to derive the opera-
tional CIR and PIR created by the application of the policy. When a specific adaptation-rule is
removed, the default constraints for pir and cir apply.

Parameters
adaptation-rule — Specifies the adaptation rule to be used while computing the operational CIR or

PIR value.
Values pir — Defines the constraints enforced when adapting the PIR rate defined within
the queue queue-id rate command. The pir parameter requires a qualifier that
