    Duplex Settings

    This weekend we are going to be doing some reconfiguring of our Switches and was thinking it may be a good time to play with some settings. I was thinking all of our switches ( Cisco 3750-E) Support full duplex and I think most of our servers do as well ( Proliant DL 360's and 380's G1-G6s as well as a rack of Bl460c)
    Should I manually set the ports on the switches and the Nics in the boxes to full duplex or should I just leave them at auto. I have read mostly positive things saying yes to set everything to full and I would get better performance. Just wanted to get a feel for how everyone else was doing it

    You'll only see an increase in performance using manual settings if you have two devices that cannot negotiate full speed sucessfully.

    It doesn't happen as much now, but I still come across some NIC's that can't seem to get it 'right' and you end up having 10Mbs/half duplex instead of 100Mbs/full duplex.

    The official Cisco line is that auto is the fail safe mode, and you 'auto-not' leave your switchports auto, but configure them as you need to suit your network.

    My method is to set the switchports to 100/full and let the NIC's be auto, and all works fine. It also means you don't have to set the speed/duplex at the NIC's, if you can at all.

    That said, mostly switches are set to auto these days and work sucessfully.
