DiffServ Configuration Overview
To use DiffServ for QoS, you must enable DiffServ (see Enable the DiffServ Mode and View
the DiffServ Status on page 161) and define the following categories and their criteria:
1. Class. Create classes and define class criteria (see Configure a DiffServ Class on
page 163).
2. Policy. Create policies, associate classes with policies, and define policy statements (see
Configure a DiffServ Policy on page 168).
3. Service. Add a policy to an inbound interface (see Configure the DiffServ Service Interface
on page 174).
Packets are classified and processed based on defined criteria. The classification criteria are
defined by a class. The processing is defined by a policy’s attributes. Policy attributes can 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.
Configure DiffServ Settings
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 can be defined
on a per-class instance basis, and it is these attributes that are applied when a match occurs.
The configuration process begins with defining one or more match criteria for a class. Then
one or more classes are added to a policy. Policies are then added to interfaces.
Packet processing begins by testing the match criteria for a packet. The All class type option
specifies that each match criteria within a class must evaluate to true for a packet to match
that class. The Any class type option specifies that at least one match criteria must evaluate
to true for a packet to match that class. Classes are tested in the order in which they were
added to the policy. A policy is applied to a packet when a class match within that policy is
found.
Enable the DiffServ Mode and View the DiffServ Status
You can enable the DiffServ mode and view the DiffServ general status group information,
which includes the current administrative mode setting as well as the current and maximum
number of rows in each of the main DiffServ private MIB tables.
 To enable the DiffServ mode and view the DiffServ status
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is off-network using an Ethernet cable.
2. Launch a web browser.
