Configuring Bridge Filters
Filtering is the method by which the network manager controls usage of an inter-
network. A filter permits or denies (depending on how it is configured) 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 page 16-10). To review existing
filters, press
[F]
at the Filter Definitions and Applications Configuration Menu (or
[A], [A], [E], [F], [F]
from the Main Menu).
Configuring Filter Definitions

[G]

Any other requested information, noting the values in Table 16-2 (on page 16-
8) through Table 16-6 (on page 16-10). (Press
[Enter]
at a prompt to accept a

The display will depend on the filter category. The following figure shows an example
of a MAC filter record.
