Figure 99 List Forwarding Table
The List Forwarding Table identiﬁes the port on which a certain MAC address is
located. This can be an Ethernet port or an ATM VC. Using the information in the
List Forwarding table, the bridge knows where to send a MAC address when it
receives one. If the Ethernet port receives a packet, and the destination MAC
address is not in the List Forwarding table, the port broadcasts the packet—sends
it to all Vxs associated with that port.
The List Forwarding Table includes the following columns of information:
MAC Address — The destination MAC address.
Disp. — Disposition:
Bridge — The default disposition.
Flood — Flood the frame on all available VCs.
Filter — Drop this frame.
L_Static — Destination MAC address is in Bridge Static Table.
SRC_Address_Filtering — User-conﬁgured source address ﬁlter.
DEST_Address_Filtering — User-conﬁgured destination address ﬁlter.
