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

internally to represent the priority of the traffic.
shows the default CoS-to-DSCP map.
If these values are not appropriate for your network, you need to modify them.
