Hubs and switches for me. I have found both the fxp and rl cards work well
at duplex negotiation on my HP and cat2900 switches, but not against some
IMC media convertors, 50% of my dumb hubs (everything from 3com - i.e. big
name brands-- to ones manufactured on boats in international waters) and
cat1900 switches. Basically, I have yet to find a card that works reliably
enough for me under any OS against any switch/hub to auto detect anything
other than 10BaseT/UTP Half Duplex. So even under NT (eg Intel Pro NICs
dont get it right on my SMC Tigerswitch on NT 4.0) I will set the speed and
duplex settings to match the switch/hub port. Why let NICs/drivers guess,
when you can 'give them the right answer' and not have to worry about it.
This is policy for our entire network and generally means one less variable
to worry about when diagnosing network problems.
