The percent-rate command is supported in a SAP ingress QoS policy for pir and cir parameters for both queues and policers, with the fir parameter supported only for queues on FP4 hardware that is ignored when the related policy is applied to FP2- or FP3-based hardware. For pir, the range is 0.01 to 100.00, and for cir and fir, the range is 0.00 to 100.00.
For queues, when the queue rate is percent-rate, either a local-limit or a port-limit can be applied.
When the local-limit is used, the percent-rate is relative to the queue’s parent scheduler rate. If there is no parent scheduler rate, or its rate is max, the port-limit is used. When the port-limit is used, the percent-rate is relative to the rate of the port (including the ingress-rate setting) to which the queue is attached. The port-limit is the default.
For policers, the percent-rate rate is always relative to the immediate parent root policer/arbiter rate or the FP capacity.
The following shows a SAP ingress QoS policy configuration:
