Create a Traffic Class

While traffic discovery creates traffic classes for the applications and services it identifies, there may be times when you will want to create a class to handle a more specific traffic type. For example, you may need to create classes for subscribers or branch offices. Or perhaps you might want to monitor and control the traffic for a particular website. In this case, you can manually create a child class under the HTTP parent class and specify a domain.

Note: To perform this task from PolicyCenter, you must first select a configuration from the Editing Configuration drop-down list at the top of the page.

To define a new traffic class:

1. Click the manage tab.

2. In the left window pane, select the class or folder that will be the parent of the class you are about to define.

3. Click class and select add. The New Traffic Class screen appears. show screen

4. In the Name field, type a descriptive name (up to 31 characters; hyphens, underscores, and periods are acceptable).

5. (Optional) To classify by an interface (main or a LEM), select the Device.

Note: Leave Device set to any unless you want to classify by an interface.

6. Choose a Protocol Family.

7. Choose a Service.

Child classes must have the service explicitly set to the service of the parent rather than relying on the service defined in the parent class.

8. Complete the entries in the New Traffic Class window to define the matching rule for the class. For descriptions of these fields, see Matching Rules.

9. Click add class.

When you add a class to a parent that has no children, a Default, match-all class is created as the sibling of the newly added class. If there is an existing policy for the parent, it is transferred to the Default class since a parent class cannot have a policy. If you later delete all the child classes, the policy will be transferred automatically back to the parent class.

Notes:

You cannot create a child class if the parent has been assigned a host accounting category.
If your unit is within one traffic class of its capacity, PacketWise will not let you create any more classes. This is due to the possibility that two classes will be created in some circumstances. For example, when you create the first child class for a parent, a Default class automatically gets created.
