Service Queue QoS Policy Commands
adaptation-rule
Syntax adaptation-rule [pir adaptation-rule] [cir adaptation-rule]
no adaptation-rule
Context config>qos>sap-ingress>queue
config>qos>sap-egress>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 rate 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
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 — 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 constraint used
when deriving the operational CIR for the queue. When the cir
parameter is not specified, the default constraint applies.
max — The max (maximum) option is mutually exclusive with
the min and closest options. When max is defined, the operational
PIR for the queue will be equal to or less than the administrative
rate specified using the rate command.
min — The min (minimum) option is mutually exclusive with the
max and closest options. When min is defined, the operational
PIR for the queue will be equal to or greater than the
administrative rate specified using the rate command.
closest — The closest parameter is mutually exclusive with the
min and max parameter. When closest is defined, the operational
PIR for the queue will be the rate closest to the rate specified using
the rate command.
