This chapter contains the CLI commands used for the QOS Differentiated Services (DiffServ) 
package. 

The user configures DiffServ in several stages by specifying:

1.

Class



creating and deleting classes 



defining match criteria for a class. Note: The only way to remove an individual 
match criterion from an existing class definition is to delete the class and re-cre-
ate it.

2.

Policy



creating and deleting policies



associating classes with a policy



defining policy statements for a policy/class combination

3.

Service



adding and removing a policy to/from a directional (i.e., inbound, outbound) 
interface

Packets are filtered and processed based on defined criteria.  The filtering criteria is defined by a 
class.  The processing is defined by a policy's attributes.  Policy attributes may be defined on a per-
class instance basis, and it is these attributes that are applied when a match occurs.

Packet processing begins by testing the match criteria for a packet. A policy is applied to a packet 
when a class match within that policy is found.
