Usage Guidelines All the maps are globally defined. All the maps, except the DSCP-to-DSCP-mutation map, are applied
to all ports. The DSCP-to-DSCP-mutation map is applied to a specific port. You can have multiple
DSCP-to-DSCP-mutation maps, and apply them to different Gigabit-capable Ethernet ports. Because a
group of twelve 10/100 Ethernet ports (Fast Ethernet 0/1 to 0/12, 0/13 to 0/24, and so forth) shares a
single DSCP-to-DSCP-mutation map, only one map can be attached to each 10/100 group.
