1000BaseT GBIC

[ciscoforum]

What is the cross over cable for 1000baseT GBIC ? same as 100baseT? I have two 3550 -24 connected on the gbic slot via 1000base-t Gbic card. But interface not up. Crossover cable is ok on the 100base-t. Any media command needed under gbic interface for 1000baset? or cable is wrong?Assuming the gbic is no problem.Thanks
