The percent-rate command is supported in a SAP egress QoS policy for pir and cir parameters for both queues and policers. For pir, the range is 0.01 to 100.00, and for cir, 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 or the agg-rate rate at egress. If there is no parent scheduler rate or agg-rate rate, or those rates are 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 egress-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 egress QoS policy configuration:
*B:PE>config>qos>sap-egress# queue 1 percent-rate
- no percent-rate
- percent-rate <pir-percent> [cir <cir-percent>] [port-limit | local-limit]
<pir-percent> : [0.01..100.00]
<cir-percent> : [0.00..100.00]
<port-limit | local-*> : keyword
*B:PE>config>qos>sap-egress# policer 1 percent-rate
- no percent-rate
- percent-rate <pir-percent> [cir <cir-percent>]
<pir-percent> : [0.01..100.00]
<cir-percent> : [0.00..100.00]
*B:PE>config>qos>sap-egress#
