how to configure DiffServ on PC6200

To use DiffServ for QoS, we need to first define the following categories and their criteria:

1. Class: create classes and define class criteria

2. Policy: create policies, associate classes with policies, and define policy statements

3. Service: add a policy to an inbound interface

Packets are classified and processed based on defined criteria. The classification 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. A policy can contain

multiples classes. When the policy is active, the actions taken depend on which class matches the packet.

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

when a class match within that policy is found.

The Differentiated Services menu page contains

If you had video on VLAN 22 and wanted to assign it a specific preference and assign it to port 1. The commands should look similar to this.

class-map match-all test22 ipv4

match vlan 22

exit

 policy-map test23 in

class test22

assign-queue 4

exit

 interface ethernet 1/g1

service-policy in test23

There are several different match criteria that can be used. The user and CLI guides outline the available options.
