28.3 Filter Rule Configuration

To configure a filter rule, type its number in Menu 21.1 – Filter Rules Summary and press [ENTER] to open menu 21.1.1 for the rule.

There are two types of filter rules: TCP/IP and Generic. Depending on the type of rule, the parameters for each type will be different. Use [SPACE BAR] to select the type of rule that you want to create in the Filter Type field and press [ENTER] to open the respective menu.

To speed up filtering, all rules in a filter set must be of the same class, for instance, protocol filters or generic filters. The class of a filter set is determined by the first rule that you create. When applying the filter sets to a port, separate menu fields are provided for protocol and device filter sets. If you include a protocol filter set in a device filters field or vice versa, the Prestige will warn you and will not allow you to save.
