Configuring Bridge Filters
Filtering is the method by which the network manager controls usage of an inter-
network. A filter permits o r denies (depending on how it is configure d) some or all of
a specific type of bridged traffic across an interface. This can be helpful in such ways
as limiting unwanted or inappropraite traffic onto LANs or WANs, or preventing
access to certain devices for security purposes.
The process of configuring and using Bridge filters is as follows. Both procedures are
described later in this chapter.
1. Create a Bridge Filter Definition record.
2. Create a Bridge Filter Applications record, which will determine how the filter
definitions will be applied.
3. Perform an on-line update of the definitions and applications (described under
"Configuring Bridge Filter Applications" on pa ge 16-1 0) . To revi ew exis ting
filters, press [F] at the Filter Definitions and Applications Configuration Menu (or
[A], [A], [E], [F], [F] from the Main Menu).

Configuring Filter Definitions

To define a filter, press [G] at the Con figure Filter Definitions and Applications M enu.
When pr om pted , enter:
●Filter Type:4 = Generic 5 = MAC (Default) 6 = LLC2 SAP
7 = Protocol 8 = Bridged native NetBIOS.
●Filter ID: 1–65535. (The default is 1.) This is simply a unique identifier.
●Any other requested information, noting the values in Table 16 -2 (on page 16-
8) th rough T able 16 -6 (on p age 16 -1 0). (Pr ess [Enter] at a prompt to accept a
default value.)
The display will depend on the filter category. The f ollowing figure shows an example
of a MAC filter record.
