Configuring Standard QoS
Beginning in privileged EXEC mode, follow these steps to configure the DSCP-trusted state on a port
and modify the DSCP-to-DSCP-mutation map. To ensure a consistent mapping strategy across both QoS
domains, you must perform this procedure on the ports in both domains:
Command
Step 1
configure terminal
Step 2
mls qos map dscp-mutation
dscp-mutation-name in-dscp to out-dscp
Step 3
interface interface-id
Step 4
mls qos trust dscp
Step 5
mls qos dscp-mutation
dscp-mutation-name
Step 6
end
Step 7
show mls qos maps dscp-mutation
Step 8
copy running-config startup-config
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

Purpose
Enter global configuration mode.
Modify the DSCP-to-DSCP-mutation map.
The default DSCP-to-DSCP-mutation map is a null map, which maps
an incoming DSCP value to the same DSCP value.
For dscp-mutation-name, enter the mutation map name. You can
•
create more than one map by specifying a new name.
For in-dscp, enter up to eight DSCP values separated by spaces.
•
Then enter the to keyword.
For out-dscp, enter a single DSCP value.
•
The DSCP range is 0 to 63.
Specify the port to be trusted, and enter interface configuration mode.
Valid interfaces include physical ports.
Configure the ingress port as a DSCP-trusted port. By default, the port
is not trusted.
Apply the map to the specified ingress DSCP-trusted port.
For dscp-mutation-name, specify the mutation map name created in
Step 2.
You can configure multiple DSCP-to-DSCP-mutation maps on an
ingress port.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
