Viewing the List Forwarding Table

The List Forwarding Table is a current forwarding table for the bridge. To open this
table, select [6] Forwarding Table from the Bridge menu. Figure 99 shows a
representative List Forwarding Table.
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.
