I have a Nokia FW with a 10/100/1000 interface connected to a Catalyst 3524XL. It is configured forzed 100-full and working ok. Last week I tried to change the switch to a Catalyst 3750G, and link was down. We changed speed, duplex, auto, etc, but link was down. ¿Any ideas?
Cabling tested twice, it happens in two differents FWs, and a laptop works ok with the same cabling and interface in 3750G.
