Bridge/Address Table
The Express 4100/4110 automatically maintains a table of MAC addresses
detected and associates those addresses with the LAN, WAN0, or WAN1
port from which they were received. This menu permits the user to adjust
the parameters or rules for the table as addresses are learned.
Address Table/Aging
Write security: 3; Read security: 5
This is the maximum time an idle MAC address remains in the table
before being removed. The value is in minutes and can range from 0
(which means never age) to 65535. The default is 5.
Address Table/Forward Policy
Write security: 3; Read security: 5
When this parameter is set to Unknown (def), any bridge packet with a
destination MAC address that is not in the bridge table is forwarded to all
other ports. When set to Known, the packet with the unknown destina-
tion MAC address is dropped and is not forwarded.
