QoS Policy Overview
A QoS policy involves three components: class, traffic behavior, and policy. You can associate a class
with a traffic behavior using a QoS policy.
Class
Classes are used to identify traffic.
A class is identified by a class name and contains some match criteria.
You can define a set of match criteria to classify packets, and the relationship between criteria can be
and or or .
z
and: The device considers a packet belongs to a class only when the packet matches all the criteria
in the class.
z
or: The device considers a packet belongs to a class as long as the packet matches one of the
criteria in the class.
Traffic behavior
A traffic behavior defines a set of QoS actions for packets.
Policy
A policy associates a class with a traffic behavior.
You can configure multiple class-to-traffic behavior associations in a policy.
Configuring a QoS Policy
Follow these steps to configure a QoS policy:
1) Create a class and define a set of match criteria in class view.
2) Create a traffic behavior and define a set of QoS actions in traffic behavior view.
3) Create a policy and associate the traffic behavior with the class in policy view.
Defining a Class
To define a class, you need to specify a name for it and then configure match criteria in class view.
