The protocol dependent filter rules abbreviation are listed as follows:
31.4 Configuring a Filter Rule
To configure a filter rule, type its number in Menu 21.1.x – Filter Rules Summary and press
[ENTER] to open menu 21.1.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.
