Cisco Systems 3825 Match ip dscp, Class-map configuration, Policy-map class configuration mode

Appendix A Cisco 3825 Mobile Wireless Edge Router RAN-O Command Reference

match ip dscp

match ip dscp

To identify a specific IP differential service code point (DSCP) value as a match criterion, use the match ip dscp class-map configuration command. To remove a specific IP DSCP value from a class map, use the no form of this command.

match ip dscp ip-dscp-value [ip-dscp-value ip-dscp-value ip-dscp-value ip-dscp-value ip-dscp-value ip-dscp-value ip-dscp-value]

no match ip dscp ip-dscp-value [ip-dscp-value ip-dscp-value ip-dscp-value ip-dscp-value ip-dscp-value ip-dscp-value ip-dscp-value]

Syntax Description ip-dscp-value Specifies the exact value from 0 to 63 used to identify an IP DSCP value.

Usage Guidelines			Up to eight IP DSCP values can be matched in one match statement. For example, if you wanted the IP
			DSCP values of 0, 1, 2, 3, 4, 5, 6, or 7 (note that only one of the IP DSCP values must be a successful
			match criterion, not all of the specified IP DSCP values), enter the match ip dscp 0 1 2 3 4 5 6 7
			command.
			This command is used by the class map to identify a specific IP DSCP value marking on a packet. The
			ip-dscp-valuearguments are used as markings only. The IP DSCP values have no mathematical
			significance. For instance, the ip-dscp-valueof 2 is not greater than 1. The value simply indicates that a
			packet marked with the ip-dscp-valueof 2 is different than a packet marked with the ip-dscp-valueof 1.
			The treatment of these marked packets is defined by the user through the setting of QoS policies in
			policy-map class configuration mode.
Examples			The following example shows how to configure the service policy called priority50 and attach service
			policy priority50 to an interface. In this example, the class map called ipdscp15 will evaluate all packets
			entering interface Gigabit Ethernet 0/0 for an IP DSCP value of 15. If the incoming packet has been
			marked with the IP DSCP value of 15, the packet will be treated with a priority level of 55.
			Router(config)# class-map ipdscp15
			Router(config-cmap)# match ip dscp 15
			Router(config-cmap)# exit
