Set a Priority Policy

Priority policies are used to establish a priority for traffic without specifying a particular rate. Use a priority policy for short, non-continuous traffic flows or traffic that does not burst. The priority determines the importance of the traffic class; you specify a value from 0 to 7, where 7 is the highest priority. The Inbound/Default and Outbound/Default classes are factory-set to a priority of 3.

Note: To perform this task from PolicyCenter, you must first select a unit or draft configuration in the Configurations window. Then select the Class Tree tab from the right pane of this window, and proceed to step 2 of the procedure below.

To apply a priority policy to a traffic class:

1. Click the manage tab.

2. In the left window pane, select the class to which you want to apply a rate policy.

3. Click policy and select add. The New Policy window appears.

4. Click priority in the New Policy window.  show screen

5. Select a priority (0 through 7) from the pull-down menu. Note that 0 is the lowest priority and 7 is the highest. See Priority Guidelines.

Certain types of traffic offer specialized priority policy options. The Policy window displays buttons for the following functions if they are relevant to the selected traffic type: Diffserv and Scaling.

6. Click add policy.

Note: In order for policies to take effect, traffic shaping must be enabled. See Enable/Disable Traffic Shaping. You can also use the Application Policy Manager to apply a priority policy to a traffic class. For details, see Set an Application Policy or Partition.
