queue-override
Syntax [no] queue-override
Context config>service>vprn>if>sap>egress
config>service>vprn>if>sap>ingress
Description This command enables the context to configure override values for the specified SAP egress or
ingress QoS queue. These values override the corresponding ones specified in the associated SAP
egress or ingress QoS policy.
queue
Syntax [no] queue queue-id
Context config>service>vprn>if>sap>egress>queue-override
config>service>vprn>if>sap>ingress>queue-override
Description This command specifies the ID of the queue whose parameters are to be overridden.
Parameters queue-id — The queue ID whose parameters are to be overridden.
Values 1 — 32
adaptation-rule
Syntax adaptation-rule [pir adaptation-rule] [cir adaptation-rule]
no adaptation-rule
Context config>service>vprn>if>sap>egress>queue-override>queue
config>service>vprn>if>sap>ingress>queue-override>queue
Description This command can be used to override specific attributes of the specified queue’s adaptation rule
parameters. The adaptation rule controls 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 rate and cir apply.
Default no adaptation-rule
Parameters pir — The pir parameter 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
constraint used when deriving the operational PIR for the queue. When the rate command is not
specified, the default applies.
cir — The cir parameter defines the constraints enforced when adapting the CIR rate defined within
the queue queue-id rate command. The cir parameter requires a qualifier that defines the
