The adaptation rule provides the QoS provisioning system with the ability to adapt the administrative rates provisioned for CIR and PIR, to derive the operational rates based on the underlying capabilities of the hardware. The administrative CIR and PIR rates are translated to actual operational rates, which are enforced by the hardware meter. The rule provides a constraint when the exact rate is not available as a result of hardware capabilities. The following constraints are supported:
minimum
The system finds the next multiple of the hardware step size that is equal to or greater than the specified rate.
maximum
The system finds the next multiple of the hardware step size that is less than or equal to the specified rate.
closest
The system finds the next multiple of the hardware step size that is closest to the specified rate.
