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.
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)#
mls qos map dscp-mutation gigabitethernet1/0/2-mutation 10 11 12 13 to 30
Switch(config)#
interface gigabitethernet1/0/2
Switch(config-if)#
mls qos trust dscp
Switch(config-if)#
mls qos dscp-mutation gigabitethernet1/0/2-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.
For background information, see the
“Classification” section on page 36-5
and the
. For configuration guidelines, see the
Guidelines” section on page 36-33
.
These sections describe how to classify, police, and mark traffic. Depending on your network
configuration, you must perform one or more of these tasks:
•
