RE: Problems connectivity GE on Foundry BigIron to Cisco 2950T
- From: David Hubbard

You are using a crossover cable right? If that's all set, you
do need to have neg-off on the Foundry and "no nego auto" on the
Cisco. I haven't used the rj-45 gbics in the Foundry equipment
before, not sure if that could be an issue. I would go with
the hard set 1000-full on both sides.
