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
Defaults This command has no default behavior or values.
Command Modes Class-map configuration
Command History
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-value arguments are used as markings only. The IP DSCP values have no mathematical
significance. For instance, the ip-dscp-value of 2 is not greater than 1. The value simply indicates that a
packet marked with the ip-dscp-value of 2 is different than a packet marked with the ip-dscp-value of 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
ip-dscp-value Specifies the exact value from 0 to 63 used to identify an IP DSCP value.
