Bridge Address Table Filters

With the Bridge Address Table entry shown in Table 5-1, you can use any of the following types of Bridge Address Table filtering:

•Source address

•Source address multicast

•Destination address

5.1.1 Source Address Filter

The source address filtering capability uses the source filter flag, which is a component of each entry in the FN10 Bridge Address Table. When the flag is set to ON, all packets originating from the designated MAC address are filtered. This enables the FN10 to recognize — and ignore — local traffic. Local traffic refers to data packets that only need to travel within one network segment.

5.1.2 Source Address Multicast Filter

The source address multicast filtering capability uses the multicast source filter flag in the FN10 Bridge Address Table.

When this flag is set to ON, all multicast packets originating from the designated MAC address are filtered. This is useful for preventing broadcast traffic from a particular station from being propagated to other network segments.
