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
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.
Default
adaptation-rule pir closest cir closest
Parameters
adaptation-rule — Specifies the adaptation rule to be used while computing the operational CIR or PIR
value.
Values
7950 XRS Quality of Service Guide
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 deriv-
ing 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.
