22.4 Configuring a Filter Rule

To configure a filter rule, type its number in Menu 21.x – Filter Rules Summary and press [ENTER] to open menu 21.x.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.

22.4.1 TCP/IP Filter Rule

This section shows you how to configure a TCP/IP filter rule. TCP/IP rules allow you to base the rule on the fields in the IP and the upper layer protocol, for example, UDP and TCP headers.

To configure TCP/IP rules, select TCP/IP Filter Rule from the Filter Type field and press [ENTER] to open Menu 21.x.1 – TCP/IP Filter Rule, as shown next.
