Usage Guidelines
The match ip precedence command specifies an IPv4 precedence value to use as the match criteria to
determine if packets belong to the class specified by the class map.
The precedence values are used as marking only. In this context, the IP precedence values have no
mathematical significance. For example, the precedence value of 2 is not greater than 1, but merely
indicates that a packet marked with a value of 2 is different than one marked with a value of 1. You define
the treatment of these marked packets by setting QoS policies in policy-map class configuration mode.
Before using the match ip precedence command, you must enter the class-map global configuration
command to specify the name of the class whose match criteria you want to establish.
You can enter up to four IPv4 precedence values in one match statement. For example, if you wanted the
IP precedence values of 0, 1, 2, or 7, enter the match ip precedence 0 1 2 7 command. The packet must
match only one (not all) of the specified IP precedence values to belong to the class.
You can use match ip precedence classification in input and output policy maps.
Examples
This example shows how to create a class map called class, which matches all the incoming traffic with
IP-precedence values of 5, 6, and 7:
Switch(config)# class-map match-any in-class
Switch(config-cmap)# match ip precedence 5 6 7
Switch(config-cmap)# exit
You can verify your settings by entering the show class-map privileged EXEC command.
