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.
7.2.3 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, e.g., UDP and TCP, headers.
To configure a TCP/IP rule, select TCP/IP Filter Rule from the Filter Type field and press
[ENTER]
to open
Menu 21.1.1 – TCP/IP Filter Rule
, as shown below.
