Alot of switches have a full-duplex light which illuminates when this is enabled on the attached nic. For that matter, a lot of nics have a full duplex light on them. I usually use 3com 3c905 nics and they have always defaulted to full duplex mode. In one instance the card had been set on a windows machine to half. I used the vortex (3c905) utility from this guy on linux to flip the bit back.
