mls qos srr-queue output cpu-queue

Use the mls qos srr-queue output cpu queue global configuration command to assign CPU-generated

control plane packets to an egress queue and to specify the threshold values. Use the no form of this

command to return to the default setting.

Syntax Description

queue queue-id

threshold threshold-id Specify a threshold value and ID. The range is 1 to 3.

The default egress queue value is 2.

Usage Guidelines

Use this command to specify an egress queue and a threshold ID for CPU-generated traffic.

You can assign each packet that flows through the switch to a queue and to a threshold. Specifically, you

map Differentiated Services Code Value (DSCP) or Class of Service (CoS) values to an egress queue-set

and map DSCP or CoS values to a threshold ID. You use the mls qos srr-queue output dscp-map queue

queue-id {dscp1...dscp8 | threshold threshold-id dscp1...dscp8} or the mls qos srr-queue output

cos-map queue queue-id {cos1...cos8 | threshold threshold-id cos1...cos8} global configuration

command. When you mark a CPU-generated control plane packet with a DSCP or CoS value, you can map

traffic to any of the four egress queues.

This example shows how to specify an egress queue for CPU-generated traffic. In this example, the

traffic is sent from queue 2 and has a threshold ID of 1.

Switch(config)# mls qos srr-queue output cpu queue 2 threshold 1

Switch(config)# cpu traffic qos dscp 20

Note that threshold 3 specifically applies to CPU-generated traffic. For example: If you explicitly issue

the mls qos srr-queue output cpu queue 3 threshold 3 command, then traffic is always sent through

queue 3 regardless of the dscp-map or cpu traffic qos marking settings.

You can verify your settings by entering the show mls qos maps, the show mls qos interface

[interface-id] buffers, or the show mls qos queue-set privileged EXEC commands.
