Service Egress QoS Queue
To create a service egress queue parameters, define the following:
• A new queue ID value. The system will not dynamically assign a value.
• Define queue parameters. Egress queues support explicit and auto-expedite hardware
queue scheduling, and parent virtual scheduler definition.
The following displays an egress QoS policy configuration:

Percent-Rate Support
The percent-rate command is supported for pir and cir parameters for both queues and
policers. Also supported is the capability of specifying the rate as a percentage value of the
line rate for sap-ingress and sap-egress qos policies. It is supported for both queues and
policers. The user has the option of specifying percent-rate for pir and cir parameters. For
pir, the range is 0.01 to 100.00, and for cir, the range is 0.00 to 100.00.
The rate can be also configured using the existing keyword rate in Kbps.
For queues, when the queue rate is in percent-rate either a local-limit or a port-limit can be
applied.
