Bridge
The B menu is used to set up the bridge parameters for the TA 544. The bridging function runs at the
RIDGE
Media Access Control (MAC) level which allows any protocol packets that run over Ethernet to be for-
warded. Bridging can run concurrently with IP. However, when IP routing is active, IP packets (which
include ARP packets) are not bridged.
Mode
This is used to enable the bridge function.
Address Table
The TA 544 automatically maintains a table of MAC addresses detected and associates those addresses
with the LAN or WAN port from which they were received.
