This command defines the method used by the system to derive the operational CIR and PIR rates when the queue is provisioned in hardware. For the cir and pir parameters, the system attempts to find the best operational rate depending on the defined constraint.
The no form of this 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 cir and pir apply.
adaptation-rule pir closest cir closest
Specifies the adaptation rule and defines the constraints enforced when adapting the CIR rate defined using the queue queue-id rate command. The cir parameter requires a qualifier that defines the constraint used to derive the operational CIR rate for the queue. When the cir parameter is not specified, the default constraint applies. The max (maximum), min (minimum), and closest qualifiers are mutually exclusive. See Table: Supported hardware rates and burst step sizes for CIR and PIR values on the 7210 SAS-Mxp, 7210 SAS-R6, 7210 SAS-R12, 7210 SAS-Sx/S 1/10GE, and 7210 SAS-T for information about supported hardware step-size rates.

7210 SAS-T (in access-uplink and network modes), 7210 SAS-Sx 1/10GE: standalone and standalone-VC, and 7210 SAS-Sx 10/100GE
This command defines the administrative Peak Information Rate (PIR) and the administrative Committed Information Rate (CIR) parameters for the queue. The PIR defines the maximum rate that the queue can transmit packets through the port. Defining a PIR does not necessarily guarantee that the queue can transmit at the intended rate. The actual rate sustained by the queue can be limited by oversubscription factors or available egress bandwidth. The CIR defines the rate at which the system prioritizes the queue over other queues competing for the same bandwidth.
The rate command can be executed at anytime, altering the PIR and CIR rates for all queues created on the access ports.
The no form of this command reverts all queues created with the queue ID by association with the QoS policy to the default PIR (max) and CIR (0) parameters.
Specifies the administrative CIR rate, in kilobits, for the queue. The cir parameter overrides the default administrative CIR used by the queue. When the rate command is executed, a valid CIR setting must be explicitly defined. When the rate command has not been executed or the cir parameter is not explicitly specified, the default CIR (0) is assumed.
Fractional values are not allowed and must be given as a positive integer.
Specifies the administrative PIR rate, in kilobits, for the queue. When the rate command is executed, a PIR setting is optional. When the rate command has not been executed, the default PIR of max is assumed.
Fractional values are not allowed and must be given as a positive integer.
The actual PIR rate is dependent on the queue’s adaptation-rule parameters and the actual hardware where the queue is provisioned.

This command configures the scope as exclusive or template. The policy’s scope cannot be changed if the policy is applied to multiple ports.
The no form of this command reverts the scope of the policy to the default.
template
Specifies that the policy can only be applied to one interface port. If a policy with an exclusive scope is assigned to a second interface an error message is generated. If the policy is removed from the exclusive interface, it will become available for assignment to another exclusive interface. The system default policies cannot be put into the exclusive scope. An error will be generated if scope exclusive is executed in any policies with a policy ID equal to 1.
Specifies that the policy can be applied to multiple ports on the router.
