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 automagically
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.
