the bigiron wants (iirc):
i strongly suggest you peruse the cli reference for both devices.
On the foundry GBIC blades you can't configure the speed and duplex
settings, they only support 1000-full.
Error - can't change speed and duplex mode
I've dug through as much information as I can about the cisco 2950T and
802.3z/802.3ab and disabling the auto-negiation. There appears to be no
command at all available to do this.
The cabling arrangement is:
Foundry -- Straight -- Patch -- Underfloor -- Patch -- Crossover -- Cisco
GBIC Cable Panel Straight Panel Cable
If I replace the final crossover cable with a straight, change the foundry
to a 10/100 port, and plug the final end into a host NIC instead of the
cisco I get a connection. Crossover cable has been changed twice now, and
the RJ45 GBIC was previously working in a cisco 6500.
I am extensively familar (at least I believe I am) with both these models,
and this one has me stumped.
If nobody else can see any configuration errors I guess I'm down to
