Description
This command specifies 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 adaptation-rule pir closest cir closest
Parameters 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 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.
adaptation-rule — Specifies the adaptation rule to be used while computing the operational CIR or PIR
value.
Values 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.
