Bridge/Address Table

The Router Option Module automatically maintains a table of MAC
addresses detected and associates those addresses with the LAN,
WAN0, or WAN1 port from which they were received. WAN0 rep-
resents Bridge Group 1, and WAN1 represents Bridge Group 2. 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 for-
warded to all other ports. When set to Known, the packet with the
unknown destination MAC address is dropped and is not forward-
ed.
