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.
A class is a set of match criteria for identifying traffic. It uses the AND or OR operator:
If the operator is AND, a packet must match all the criteria to match the class.
If the operator is OR, a packet matches the class if it matches any of the criteria in the class.
Traffic behavior
A traffic behavior defines a set of QoS actions to take on packets, such as filtering and redirect.
Policy
By associating a traffic behavior with a class in a QoS policy, you apply the specific set of QoS actions to
the class of traffic.
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.
4) Apply the policy to an interface.
Defining a Class
To define a class, you need to specify a name for it and then configure match criteria in class view.
Follow these steps to define a class:
