The QoS feature contains Differentiated Services (DiffServ) support that allows
traffic to be classified into streams and given a certain QoS treatment in
accordance with defined per-hop behaviors.
Standard IP-based networks are designed to provide best-effort data delivery
service. Best-effort service implies that the network delivers the data in a timely
fashion, although there is no guarantee that it will. During times of congestion,
packets may be delayed, sent sporadically, or dropped. For typical Internet
applications, such as email and file transfer, a slight degradation in service is
acceptable and in many cases unnoticeable. However, on applications with strict
timing requirements, such as voice or multimedia, any degradation of service has
undesirable effects.
A DiffServ configuration begins with defining class maps, which classify traffic
according to their IP protocol and other criteria. Each class map can then be
associated with a policy map, which defines how to handle the traffic class.
Classes that include time-sensitive traffic can be assigned to policy maps that
give precedence over other traffic.
You can use the Class Map page to define the classes of traffic, and use the
Map
page to define the policies and associate the class maps to them.
Configuring an IPv4 Class Map
To add and configure an IPv4 class map:
Select Quality of Service > Class Map.
In the Class Map Name field, enter the name for the new class map. The name can
contain from 1 to 31 alphanumeric and special characters. Spaces are not
allowed.
Choose IPv4 as the type of class map from the Class Map Type list. The IPv4
class map applies only to IPv4 traffic on the WAP device.
In the Match Criteria Configuration area, configure these parameters to match
the packets to a class:
