Re: duplex mismatch

Hi Korbenda,

If you have half duplex on one side or duplex on another side you will see lot of collision errors on your interface.

I will recommed to set it on auto and let the interface negotiates itself the speed and duplex or you can manually set the speed on gig interface to 100 to match the fast ethernet interface on other side.
