The following rules apply when you create a DiffServ class:

Each class can contain a maximum of one referenced (nested) class

Class definitions do not support hierarchical service policies

A given class definition can contain a maximum of one reference to another class. You can 

combine the reference with other match criteria. The referenced class is truly a reference and 
not a copy, because additions to a referenced class affect all classes that reference it. 
Changes to any class definition currently referenced by any other class must result in valid 
class definitions for all derived classes, otherwise the switch rejects the change. You can 
remove a class reference from a class definition.

The only way to remove an individual match criterion from an existing class definition is to 
delete the class and re-create it.

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.

This command sets the DiffServ operational mode to active. While disabled, the DiffServ 
configuration is retained and can be changed, but it is not activated. When enabled, DiffServ 
services are activated.

DiffServ Class Commands

Use the DiffServ class commands to define traffic classification. To classify traffic, you specify 
Behavior Aggregate (BA), based on DSCP and Multi-Field (MF) classes of traffic (name, 
match criteria)
