Command

Modes

Interface configuration mode

Description Use this command to specify the interface Default CoS value. When Interface ingress QoS Trust is

in the untrusted mode, then the Interface Default CoS value is applied to all ingress traffic for user

priority mapping. When the interface ingress QoS Trust is in the CoS mode, then the Interface

Default CoS value is applied to all non-priority tagged ingress traffic for user priority mapping. Use

the no qos cos command to return the CoS value to the default.

Usage

Guidelines

If the interface is QoS trusted, the CoS value of the interface is used to assign a CoS value to all

untagged packets entering the interface.

Examples To set the interface CoS value to 2:

switch(conf-if-te-0/2)#qos cos 2

To return the interface CoS value to the default:

switch(conf-if-te-0/2)#no qos cos
