Predefined classes, traffic behaviors, and policies

The system predefines the following classes, traffic behaviors, and policies:
Predefine d classes
The system predefines some classes and defines general rules for the classes. You can u

Predefine d QoS policy
The system predefines a QoS policy, specifies a predefined class for the policy and a
predefined behavior with the class. The policy is named default, with the default CBQ action.
The policy default is defined as follows:
Associates the predefined class ef with the predefined traffic behavior ef.
•
Associates predefined classes af1 through af4 with the predefined traffic behavior af.
