Chapter 36 Configuring QoS

Configuring Standard QoS

Beginning in privileged EXEC mode, follow these steps to modify the DSCP-to-DSCP-mutation map. This procedure is optional.

	Command			Purpose
Step 1	configure terminal			Enter global configuration mode.
Step 2	mls qos map dscp-mutation			Modify the DSCP-to-DSCP-mutation map.
	dscp-mutation-name in-dscp to out-dscp			• For dscp-mutation-name, enter the mutation map name. You can
				create more than one map by specifying a new name.
				• For in-dscp, enter up to eight DSCP values separated by spaces.
				Then enter the to keyword.
				• For out-dscp, enter a single DSCP value.
				The DSCP range is 0 to 63.
Step 3	interface interface-id			Specify the port to which to attach the map, and enter interface
				configuration mode.
				Valid interfaces include physical ports.
Step 4	mls qos trust dscp			Configure the ingress port as a DSCP-trusted port. By default, the port
				is not trusted.
Step 5	mls qos dscp-mutation			Apply the map to the specified ingress DSCP-trusted port.
	dscp-mutation-name			For dscp-mutation-name, enter the mutation map name specified in
				Step 2.
Step 6	end			Return to privileged EXEC mode.
Step 7	show mls qos maps dscp-mutation			Verify your entries.
Step 8	copy running-config startup-config			(Optional) Save your entries in the configuration file.
		To return to the default map, use the no mls qos dscp-mutationdscp-mutation-nameglobal
		configuration command.
		This example shows how to define the DSCP-to-DSCP-mutation map. All the entries that are not
		explicitly configured are not modified (remains as specified in the null map):
		Switch(config)# mls qos map dscp-mutation mutation1 1 2 3 4 5 6 7 to 0
		Switch(config)# mls qos map dscp-mutation mutation1 8 9 10 11 12 13 to 10
		Switch(config)# mls qos map dscp-mutation mutation1 20 21 22 to 20
		Switch(config)# mls qos map dscp-mutation mutation1 30 31 32 33 34 to 30
		Switch(config)# interface gigabitethernet1/0/1
		Switch(config-if)# mls qos trust dscp
		Switch(config-if)#mls qos dscp-mutation mutation1
		Switch(config-if)# end
		Switch# show mls qos maps dscp-mutation mutation1
		Dscp-dscp mutation map:
		mutation1:
		d1 : d2 0 1 2 3 4 5 6 7 8 9
