bridge - combine all local network cards as a bridge in order to sniff network traffic
Bridge combines all local ethernet interfaces it can find and creates a network bridge between all networks you've connected to your TRK.
You should commonly use it between a router and your lan (with a cross cable to the router) to be able to sniff network traffic using tcpdump.
Another usage is to connect it between a PC and the rest of the network to be able to see what traffic the PC generates. Windows computers don't have decent network monitoring tools out-of-the-box, so this is a quick-and-dirty solution which is non-intrusive.
It's recommended that at most only 1 ethernet interface has an ip-address as it tends to do strange things on your network if more than 1 nic has an ip-address.
