Chapter 36 Configuring QoS
Configuring Standard QoS
To return a port to its non-trusted state, use the no mls qos trust interface configuration command. To
return to the default DSCP-to-DSCP-mutation map values, use the no mls qos map dscp-mutation
dscp-mutation-name global configuration command.
return to the default DSCP-to-DSCP-mutation map values, use the no mls qos map dscp-mutation
dscp-mutation-name global configuration command.
This example shows how to configure a port to the DSCP-trusted state and to modify the
DSCP-to-DSCP-mutation map (named gi1/0/2-mutation) so that incoming DSCP values 10 to 13 are
mapped to DSCP 30:

Switch(config)# interface gigabitethernet1/0/2
Switch(config-if)# mls qos trust dscp
Switch(config-if)# mls qos dscp-mutation gi1/0/2-mutation
Switch(config-if)# end

to those traffic classes, and attaching policies to ports.
