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

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.
