Fellows,
Auto negotiate works by sending a very fast signal to the connecting 
switch. If the switch does not respond to the signal (when not set to 
Auto)(which can not usually be seen in packet analyzers like wireshark, 
only very high end analyzers) then the sending switch drops down to 10 
half. If the connecting switch is set to 100 full there will be no 
talking between the switches. The easy rule of thumb is either set both 
switches to auto, or set both connecting ports to be the same speed and 
duplex. Auto negotiate usually works best to obtain the fastest 
communication.
Yours,
Rob
