DiffServ
The QoS feature contains Differentiated Services (DiffServ) support that allows traffic to be classified into streams
and given certain QoS treatment in accordance with defined per-hop behaviors. To use DiffServ for QoS, the web
pages accessible from the Differentiated Services menu first be used to define the following categories and their
criteria:
1. Class: Create class 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 the 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 multiple 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.

DiffServ Class and Class Configuration pages are used to add a new DiffServ Class name, or to rename or delete
an existing class. This feature allows the user to define the criteria to associate with a DiffServ Class. As packets
are received, these DiffServ Class is used to prioritize packets.
The fields available on the Class Configuration page depend on whether you create a new class or configure
a class that has already been created.
