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 individ-
ually, 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 rate and cir apply.
Default
no adaptation-rule
Parameters
pir — The pir parameter defines the constraints enforced when adapting the PIR rate defined within
cir — The cir parameter defines the constraints enforced when adapting the CIR rate defined within

constraint used when deriving the operational PIR for the queue. When the rate command is not
specified, the default applies.

queue, while maintaining a minimum offset.
Values
max — The max (maximum) keyword 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) keyword 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.
