Hello,
I have a WS-2960-24TC-L running with c2960-lanbase-mz.122-40.SE.bin with two GLC-GE-100FX= in it.
I am trying to link this switch to a 3750 with a GLC-GE-100FX= and a WS-2955C-12.
The 2960 always auto negotiate to 100 half with both switches. In the 3750 I can force the port to Full duplex but the DUPLEX command in not ava lable on gig 0/1-2.
I would be nice to have a 100 Full link between the switches.
Can you help me ?

What are your ports configured like on the 3750 and the 2955? Try setting each side for autonegotiate. This should bring the connection up at 100/full.

Current GigE is full-duplex only.
You might try using a 10/100 port (as a trunk port if necessary).
You can also try another cable, preferably a commercially made cable in good condition. Poorly terminated hand-made cables, or cables that have been kinked, stretched, crushed {etc} can cause the ports to downshift.
Good Luck
