I've been around long enough to remember having an AUI NIC that would take down a segment even when the NIC WAS NOT PLUGGED INTO THE PC. Suspicion was that there was a short in the transceiver that was causing massive reflections back into the segment.
This is annoying. I once did a similar thing to a netgear "managed" switch setup in two VLANs. Experimenting, I setup a crossover cable between the two VLANs to see how real the separation was. My theory was that it would work like having two separate switches. I was wrong. It took down the whole network as if I had run a crossover back into a switch that wasn't partitioned. I don't know whether or not this is a bug or not, but it makes me wonder just how good this netgear managed switch is and if I should replace it with something better for my internal DMZ purposes.
