This procedure is optional.
Command
Step 1
configure terminal

mls qos map ip-prec-dscp
dscp1...dscp8
Step 3
end
Step 4

To return to the default map, use the no mls qos ip-prec-dscp global configuration command.
This example shows how to modify and display the IP-precedence-to-DSCP map:
Switch(config)# mls qos map ip-prec-dscp 10 15 20 25 30 35 40 45
Switch(config)# end
Switch# show mls qos maps ip-prec-dscp

Configuring the Policed-DSCP Map
You use the policed-DSCP map to mark down a DSCP value to a new value as the result of a policing
and marking action.
The default policed-DSCP map is a null map, which maps an incoming DSCP value to the same DSCP
value.
Beginning in privileged EXEC mode, follow these steps to modify the policed-DSCP map. This
procedure is optional.
Command
Step 1
configure terminal
Step 2
mls qos map policed-dscp dscp-list to
mark-down-dscp
Step 3
end
Step 4
show mls qos maps policed-dscp
Step 5
