Chapter 24 Configuring QoS

Configuring Quality of Service (QoS)

	Command	Purpose
Step 3 match {cos cos-listip dscp dscp-list		Define the match criterion to classify traffic. By default, no match criterion
	ip precedence ip-precedence-list	is defined.
	qos-group value vlan vlan-list}	Only one match type per class map is supported.
		• For cos cos-list, enter a list of up to four CoS values in a single line to
		match against incoming packets. Separate each value with a space. You
		can enter multiple cos-listlines to match more than four CoS values. The
		range is 0 to 7.
		• For ip dscp dscp-list, enter a list of up to eight IPv4 DSCP values to
		match against incoming packets. Separate each value with a space. You
		can enter multiple dscp-listlines to match more than eight DSCP values.
		The numerical range is 0 to 63. You can also configure DSCP values in
		other forms. See the “Classification Based on IP DSCP” section on
		page 24-9.
		• For ip precedence ip-precedence-list, enter a list of up to four IPv4
		precedence values to match against incoming packets. Separate each
		value with a space. You can enter multiple ip-precedence-listlines to
		match more than four precedence values. The range is 0 to 7.
		• For vlan vlan-list,specify a VLAN ID or a range of VLANs to be used
		in a parent policy map for per-port, per-VLAN QoS on a trunk port. The
		VLAN ID range is 1 to 4094.
		• For qos-groupvalue, specify the QoS group number. The range is
		0 to 7. Matching of QoS groups is supported only in output policy maps.
Step 4
	end	Return to privileged EXEC mode.
Step 5
	show class-map	Verify your entries.
Step 6
	copy running-config startup-config	(Optional) Save your entries in the configuration file.

This example shows how to create a class map called class2, which matches incoming traffic with DSCP values of 10, 11, and 12.

Router(config)# class-map match-any class2

Router(config-cmap)#match ip dscp 10 11 12

Router(config-cmap)# exit
