Configuring PFC QoS

Configuring Egress DSCP Mutation on a PFC3

Note The PFC2 does not support egress DSCP mutation.

These sections describe how to configure egress DSCP mutation on a PFC3:

•Configuring Named DSCP Mutation Maps, page 42-82

•Attaching an Egress DSCP Mutation Map to an Interface, page 42-83

Configuring Named DSCP Mutation Maps

To configure a named DSCP mutation map, perform this task:

	Command	Purpose
Step 1
	Router(config)# mls qos map dscp-mutation	Configures a named DSCP mutation map.
	map_name dscp1 [dscp2 [dscp3 [dscp4 [dscp5 [dscp6
	[dscp7 [dscp8]]]]]]] to mutated_dscp
	Router(config)# no mls qos map dscp-mutation	Reverts to the default map.
	map_name
Step 2
	Router(config)# end	Exits configuration mode.
Step 3
	Router# show mls qos maps	Verifies the configuration.

When configuring a named DSCP mutation map, note the following information:

•You can enter up to 8 DSCP values that map to a mutated DSCP value.

•You can enter multiple commands to map additional DSCP values to a mutated DSCP value.

•You can enter a separate command for each mutated DSCP value.

This example shows how to map DSCP 30 to mutated DSCP value 8:

Router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)# mls qos map dscp-mutation mutmap1 30 to 8

Router(config)# end

Router#

This example shows how to verify the configuration:

Router#	show	mls qos map				begin DSCP mutation
DSCP mutation map mutmap1:										(dscp= d1d2)
d1 : d2 0 1 2 3 4 5 6 7 8 9
