Unicast Forwarding Database Configuration
The Unicast Forwarding Database Configuration Menu allows you to view
and search for addresses in the IntraCore 8000’s MAC Forwarding Table. It
also provides options for displaying MAC addresses and IP/MAC binding
by individual port or by VLAN.
The MAC Forwarding Table is a table of node addresses that the IntraCore
8000 automatically builds by “learning.” It performs this task by monitoring
the packets that pass through the IntraCore 8000, checking the source and
destination addresses, and then recording the source address information in
the table.
The IntraCore 8000 uses the information in this table to decide whether a
frame should be forwarded to a particular destination port or “flooded” to all
ports other than the received port. Each entry consists of three parts: the
MAC address of the device, the port number on which it was received, and
the VLAN number.
K Note: The MAC address table can hold a maximum of
8,192 entries.
When you type d in the Configuration Menu, the Unicast Forwarding
Database Configuration Menu appears, as shown in Figure 3-17.
