Classifying Traffic Using a Class Map

Creating a Class Map

To create a class map and specify the way in which the router should classify traffic, enter the following
commands beginning in global configuration mode:
Command
Step 1
Router(config)# class-map class-map-name
Step 2
Router(config-class-map)# match
match_statement

Configuration Examples for Classifying Traffic

Example 2-1
traffic using the even UDP port number, which must be within the specified range. In this example, the
lowest port number can be 16384 and the highest port number can be 16383. The data class map matches
traffic using IP precedence 1 and the application class map matches using IP precedence 2.
Example 2-1
Router(config)# class-map voice
Router(config-cmap)# match ip rtp 16384 16383
Router(config-cmap)# exit
Router(config)# class-map data
Router(config-cmap)# match ip precedence 1
Router(config-cmap)# exit
Router(config)# class-map application
Router(config-cmap)# match ip precedence 2
Example 2-2
access list 1 or that have an IP precedence value of 3 or 7.
Example 2-2
Router(config)# class-map class1
Router(config-cmap)# match access-group 1
Router(config-cmap)# match ip precedence 3 7
