Description This command defines the method used by the system to derive the operational CIR and PIR settings
when the meter 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 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 adaptation-rule cir closest pir closest
Parameters
adaptation-rule — Specifies the adaptation rule to be used while computing the operational CIR or
pir — Defines the constraints enforced when adapting the PIR rate defined within the meter meter-id
cir — Defines the constraints enforced when adapting the CIR rate defined within the meter meter-id
max — The max (maximum) option is mutually exclusive with the min and closest options. When
closest — The closest parameter is mutually exclusive with the min and max parameter. When

Description
This command provides a mechanism to override the default reserved tokens for the meter. The com-
mitted burst size parameter specifies the maximum burst size that can be transmitted by the source
while still complying with the CIR. If the transmitted burst is lower than the CBS value then the pack-

rate command. The pir parameter requires a qualifier that defines the constraint used when
deriving the operational PIR for the meter. When the rate command is not specified, the default
applies.
rate command. The cir parameter requires a qualifier that defines the constraint used when
deriving the operational CIR for the meter. When the cir parameter is not specified, the default
constraint applies.
max is defined, the operational PIR/CIR will be the next multiple of 64 kbps that is equal to or
lesser than the specified rate.
min
The min (minimum) option is mutually exclusive with the max and closest options. When min is
defined, the operational PIR/CIR will be the next multiple of 64 kbps that is equal to or higher
than the specified rate.
closest is defined, the operational PIR/CIR will be the next multiple of 64 kbps that is closest to
the specified rate.
