Switch(config)# class-map cm-4

This example shows how the default traffic class is automatically placed at the end of policy-map pm3
even though class-default was configured first:
Switch# show policy-map pm3
Policy Map pm3
Class cm-3
set dscp 4
Class cm-4
trust cos
Class class-default

Classifying, Policing, and Marking Traffic by Using Aggregate Policers
Note To use policing and marking, the switch must be running the LAN Base image.
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.
