All the maps, except the DSCP-to-DSCP-mutation map, are globally defined and are applied to all ports.

Configuring the CoS-to-DSCP Map

You use the CoS-to-DSCP map to map CoS values in incoming packets to a DSCP value that QoS uses

internally to represent the priority of the traffic.

If these values are not appropriate for your network, you need to modify them.

Beginning in privileged EXEC mode, follow these steps to modify the CoS-to-DSCP map. This

procedure is optional.

configure terminal

mls qos map cos-dscp dscp1...dscp8

show mls qos maps cos-dscp

copy running-config startup-config

To return to the default map, use the no mls qos cos-dscp global configuration command.

This example shows how to modify and display the CoS-to-DSCP map:

Switch(config)# mls qos map cos-dscp 10 15 20 25 30 35 40 45

Switch(config)# end
