Network Queue QoS Policy 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
69. Only one FC can be mapped to one queue. Queue-id 8 is the highest priority and Queue-
id 1 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 priority traffic should be mapped to high priority FC. Mapping traffic to high priority FC
does not necessarily guarantee high priority treatment since the scheduler policy can influence the
relative priority among the queues.
queue-id — The queue-id for the queue, expressed as an integer. The queue-id uniquely identifies the queue
Parameters
within the policy. This is a required parameter each time the queue command is executed.
Values
adaptation-rule
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
operational 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.
Default
adaptation-rule cir closest pir closest
Parameters
adaptation-rule — Specifies the adaptation rule to be used while computing the operational CIR or PIR
value.

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 defines the
