Interface for Bridge
Bridge can be used in the following interfaces.
Network port using static IP address
Aggregation interface
Convert Connection Using LLCF
You can use the bridge port control commands in a Terminal.
A bridge interface consists of more than 2 network interfaces. When even one of the physical network
port link goes down, Link Loss Carry Forward (LLCF) brings down all the other links in the bridge. Only
when all the ports get linked back, the bridge port will be considered linked. This feature is often used
with routing, and is only available if the network port driver supports LLCF.
