Defining A Traffic Behavior; Defining A Policy - HP FlexNetwork 6600 Configuration Manual

Defining a traffic behavior

A traffic behavior is a set of QoS actions (such as traffic filtering, shaping, policing, and priority
marking) to take on a class of traffic.
The system pre-defines some traffic behaviors and defines general QoS actions for them. A
user-defined behavior cannot be named the same as a system-defined behavior. You can use these
behaviors when defining a policy. The system-defined behaviors are as follows:
•
ef—Expedited forwarding.
•
af—Assured forwarding.
•
be—Best-effort.
•
be-flow-based—Uses the weighted random early detection (WRED) drop policy.
To define a traffic behavior:
Step
1. Enter system view.
2. Create a traffic behavior and
enter traffic behavior view.
3. Configure actions in the
traffic behavior.

Defining a policy

Configuring parent QoS policy
You associate a behavior with a class in a QoS policy to perform the actions defined in the
behavior for the class of packets.
The system provides a pre-defined QoS policy named default. It includes the associations
between predefined classes and predefined traffic behaviors:
Class ef with behavior ef.
Classes af1 through af4 with behavior af.
Class default-class with behavior be.
You cannot name a user-defined QoS policy the same as the system-defined QoS policy.
To associate a class with a behavior in a policy:
Step
1. Enter system view.
2. Create a policy and enter policy view.
3. Associate a class with a behavior in the policy.
NOTE:
On some devices, if the ACL contains deny rules, the if-match clause is ignored and the matching
process continues.
Configuring QoS policy nesting
You can reference a QoS policy in a traffic behavior to re-classify the traffic class associated with the
behavior and take action on the re-classified traffic as defined in the policy. The QoS policy
