I tried to connect a 7941(phone A) to catalyst 3560, but the screen showed Ethernet disconnected. I used another phone(phone B) with good condition and connected to the same port on 3560, the same message appeared. I then connected phone A to a different port, it worked fine with the same cable. I also trid to connect a pc to the "faulty" port, the network traffic was fine.
Very strange, isn't it? Can anyone offer help to diagnose the problem?
