I'm assuming you are using the GigaStack? Well, if you use both ports on the GigaStack, you will get half-duplex connectivity while using only one port provides full-duplex.

Hi There


I have seen this happen on more than one occasion when ports are left to auto configure.


I always hard code all my switch ports to the speed and duplex settings I require, rather than hoping that whatever I link together will configure themselves as I want.


Edit: Sorry Edison got in before me. I assumed uplinking and not stacking. I am unfamiliar with switch stacking.


Best Regards,


Michael
