Configuring Standard QoS
Beginning in privileged EXEC mode, follow these steps to modify the DSCP-to-DSCP-mutation map.
This procedure is optional.
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 to the default map, use the no mls qos dscp-mutation dscp-mutation-name global
configuration command.
This example shows how to define the DSCP-to-DSCP-mutation map. All the entries that are not
explicitly configured are not modified (remains as specified in the null map):
Switch(config)# mls qos map dscp-mutation mutation1 1 2 3 4 5 6 7 to 0
Switch(config)# mls qos map dscp-mutation mutation1 8 9 10 11 12 13 to 10
Switch(config)# mls qos map dscp-mutation mutation1 20 21 22 to 20
Switch(config)# mls qos map dscp-mutation mutation1 30 31 32 33 34 to 30
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# mls qos trust dscp
Switch(config-if)# mls qos dscp-mutation mutation1
Switch(config-if)# end
Switch# show mls qos maps dscp-mutation mutation1
Dscp-dscp mutation map:

Purpose
Enter global configuration mode.
Modify the DSCP-to-DSCP-mutation map.
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 which to attach the map, 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, enter the mutation map name specified in
Step 2.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
