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

I second that. I always crimp (or check) for it.
Also watch for Cat 6 cabling ... 23 gauge is hell to crimp. 24 is
livable but takes twice as much time to do than Cat 5e.

Hi,
I'm having a right mare trying to get a Foundry BigIron to connect up to a
cisco 2950T, via Gigabit copper.
The Foundry BigIron is using a cisco RJ45/copper GBIC that was pulled from
a live cisco 6500, where it was working fine. The cisco 2950T has two
fixed 10/100/1000 RJ45 ports.
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.

Hi,
Yup, it's definately a cross-over cable. ;) I had already tried this
suggestion but the cisco 2950T doesn't appear to have the no nego auto
command :/
(config)#int Gi0/2
(config-if)#no n?
% Unrecognized command
(config-if)#no n
(config-if)#no neg auto

Cisco commands-

On the foundry GBIC blades you can't configure the speed and duplex

Turns out that for 1000Base-T crossovers pairs 2 and 3, and 1 and 4 have
to swapped. Standard TIA-568B to TIA-568A over swaps 2 and 3.
Auto MDI/MDI-X is optional in the 1000Base-T spec so the way forward is to
