Configuring A Qos Policy - Cisco IE 3000 Software Configuration Manual

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.
This example shows how to configure a port to the DSCP-trusted state and to modify the
DSCP-to-DSCP-mutation map (named gi0/2-mutation) so that incoming DSCP values 10 to 13 are
mapped to DSCP 30:
Switch(config)# mls qos map dscp-mutation gi1/2-mutation 10 11 12 13 to 30
Switch(config)# interface gigabitethernet1/2
Switch(config-if)# mls qos trust dscp
Switch(config-if)# mls qos dscp-mutation gi1/2-mutation
Switch(config-if)# end

Configuring a QoS Policy

Configuring a QoS policy typically requires classifying traffic into classes, configuring policies applied
to those traffic classes, and attaching policies to ports.

These sections describe how to classify, police, and mark traffic. Depending on your network
configuration, you must perform one or more of these tasks:
