  Umm, what?

  Unless my understanding of the way ethernet works is seriously flawed
(which I kinda doubt, having spent three years working for Jerry
Clancy, chairman of committee IEEE 802.3, and please forgive me if
that sounds snotty) there's no way a switched ethernet network CAN
have collisions...and the duplex configuration has *nothing* to do with
it.
