23.4 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.
23.4.1 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.
