This example shows how to configure a class map to match IP DSCP and IPv6:
Switch(config)# Class-map cm-1
Switch(config-cmap)# match ip dscp 10
Switch(config-cmap)# match protocol ipv6
Switch(config-cmap)# exit
Switch(config)# Class-map cm-2
Switch(config-cmap)# match ip dscp 20
Switch(config-cmap)# match protocol ip
Switch(config-cmap)# exit
Switch(config)# Policy-map pm1
Switch(config-pmap)# class cm-1
Switch(config-pmap-c)# set dscp 4
Switch(config-pmap-c)# exit
Switch(config-pmap)# class cm-2
Switch(config-pmap-c)# set dscp 6
Switch(config-pmap-c)# exit
Switch(config-pmap)# exit
Switch(config)# interface G1/0/1
Switch(config-if)# service-policy input pm1
Classifying, Policing, and Marking Traffic by Using Aggregate Policers
By using an aggregate policer, you can create a policer that is shared by multiple traffic classes within
the same policy map. However, you cannot use the aggregate policer across different policy maps or
ports.
You can configure aggregate policers only in nonhierarchical policy maps on physical ports.
