Configuring the MAC Address Filter Table
In a Bridge Link Record, Pass (or Block) tells the system to check the MAC Address
Filter Table to find out what filtering to perform. If the Bridge Link Record specified
None, then the frame would pass without any filtering.
If the frame MAC Address is in the MAC Address Filter Table, filtering is performed
on the frame as specified in this table. The MAC Address Filter Table used in this
example specifies the filtering to be performed on MAC Address A as the incoming
source address to the bridge. Frames with Incoming Source Address A are passed at
link 1 (see Figure 32). Frames with Outgoing Source Address A are passed at link 5
(to server B), but not passed on link 6 (to server C).
