Parameters Within Policy Rules

When you are defining policy rules, both the conditions and actions may contain parameters. Parameters let you customize the specific situation in which a policy rule will be applied. Some conditions and actions may contain multiple parameters. For example, one possible condition is as follows:

where the device will be handling greater than 100 upstream reserved flows

This condition contains four different parameters. The policy wizard displays the parameters using a red font. In this example, greater than is a single parameter, as is 100, upstream, and reserved.

You can click any parameter to open a pop-up window that lets you specify the value of that parameter. Each parameter has a data type associated with it that determines the values that can be specified: some may be numbers, some may be free-form text, and some may be limited to specific sets of values. For example, the following parameter is limited to a set of text values:

If you have many policies with similar structures, you can consolidate them using policy tables that capture the differences. For more information on table-driven policies see Managing Policy Tables. To specify a parameter in a rule that uses a policy table, instead of selecting a value click Use Policy Table and then select the table column (field) representing the parameter.
