Reference Guide

The only way to remove an individual match criterion from an existing class definition is to delete the
class and re-create it.
Note
The mark possibilities for policing include CoS, IP DSCP, and IP Precedence. While the latter
two are only meaningful for IP packet types, CoS marking is allowed for both IP and non-IP
packets, since it updates the 802.1p user priority field contained in the VLAN tag of the layer 2
packet header.

DiServ Class Commands
Use the DiServ class commands to define trac classification. To classify trac, you specify Behavior
Aggregate (BA), based on DSCP and Multi-Field (MF) classes of trac (name, match criteria)
This set of commands consists of class creation/deletion and matching, with the class match commands
specifying Layer 3, Layer 2, and general match criteria. The class match criteria are also known as class
rules, with a class definition consisting of one or more rules to identify the trac that belongs to the
class.
Note
Once you create a class match criterion for a class, you cannot change or delete the criterion.
To change or delete a class match criterion, you must delete and re-create the entire class.
The CLI command root is class-map.
