7.2.2 Configuring a Filter Rule

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.
To speed up filtering, all rules in a filter set must be of the same class, i.e., 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 filter field or vice versa, the Prestige will warn you and will not allow you to save.
