Configuring the IP-Precedence-to-DSCP Map
You use the IP-precedence-to-DSCP map to map IP precedence values in incoming packets to a DSCP value
that QoS uses internally to represent the priority of the traffic.
Beginning in privileged EXEC mode, follow these steps to modify the IP-precedence-to-DSCP map. This
procedure is optional.
SUMMARY STEPS
1.
configure terminal
2.
mls qos map ip-prec-dscp dscp1...dscp8
3.
end
4.
show mls qos maps ip-prec-dscp
5.
copy running-config startup-config
DETAILED STEPS
PurposeCommand or Action
Enters global configuration mode.configure terminal
Example:
Switch# configure terminal
Step 1
Modifies the IP-precedence-to-DSCP map.
mls qos map ip-prec-dscp dscp1...dscp8
Step 2
Example:
Switch(config)# mls qos map
For dscp1...dscp8, enter eight DSCP values that correspond
to the IP precedence values 0 to 7. Separate each DSCP value
with a space.
ip-prec-dscp 10 15 20 25 30 35 40
The DSCP range is 0 to 63.
45
To return to the default map, use the no mls qos
ip-prec-dscp global configuration command.
Note
Returns to privileged EXEC mode.end
Example:
Switch(config)# end
Step 3
Verifies your entries.show mls qos maps ip-prec-dscp
Example:
Switch# show mls qos maps ip-prec-dscp
