We have installed a GLC-FE-100FX SFP in an 8 port 3560. It uses a Gigabit slot in the 3560. The interface G0/1 seems to run at Half Duplex with this SFP installed. Does anybody know why it would run at Half Duplex? I have tried hard-coding the other end but still the same result. There is no option to hard code the G0/1 interface for speed or duplex. Thanks.
