MAC Address Filtering Examples
Introduction This section shows two filtering examples. Figure 32 shows how the source address
can be used to filter frames. Figure 35 shows how the MAC Address Filter Table can
be used to filter frames by combining multiple source and destination addresses.
First Example In Figure 32, the source address (MAC Address represented by A) is used to filter
frames passing in or out of the bridge via links 1, 5, and 6 (Figure 32). Frames
originating from the station with MAC Address A are to be sent to server B but not
server C. Figure 32 shows that for bridge link 1, Incoming Source Address frames
with MAC Address A are passed, and Outgoing Source Address frames with MAC
Address A are passed on link 5, but blocked on link 6.
