CLI Command Reference

Differentiated Services (DiffServ) Commands

This section describes the commands you use to configure QOS Differentiated Services

(DiffServ).

You configure DiffServ in several stages by specifying three DiffServ components:
1. Class
-
-
2. Policy
-
-
-
3. Service
-
The DiffServ class defines the packet filtering criteria. The attributes of a DiffServ policy
define the way the switch processes packets. You can define policy attributes on a per-class
instance basis. The switch applies these attributes when a match occurs.
Packet processing begins when the switch tests the match criteria for a packet. The switch
applies a policy to a packet when it finds a class match within that policy.
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 since 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.
NOTE:
NOTE:
diffserv
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.

Creating and deleting classes.
Defining match criteria for a class.
Creating and deleting policies
Associating classes with a policy
Defining policy statements for a policy/class combination
Adding and removing a policy to/from an inbound interface
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 prior-
ity field contained in the VLAN tag of the layer 2 packet header.
Traffic to be processed by the DiffServ feature requires an IP header.
