Chaining BitStorm 2600s

downlink for the next. For example, in this illustration:

downlink for the next. For example, in this illustration:
The top unit has Port 3 (eth3) defined as its uplink and is connected to Port 3
of the next unit in the chain using a straight-through 8-position modular cable.
