You are using a crossover cable right?
I'm having a right mare trying to get a Foundry BigIron to 
connect up to a cisco 2950T, via Gigabit copper.

i was under the impression that gige spec handled crossover

According to "Ethernet, The Definitive Guide", that feature is an
optional part of the spec.

One thing I've heard people encounter is that if they use a cross-over
cable, which probably really implies a 100BASE-TX cross-over, then the
ports only go to 100Mbps. A Gig-E rated straight through, in conjunction
with the automatic crossover feature, was necessary to get to GigE.
