    Ethernet Error Speed 10 or 100 Mbps, Half or Full Duplex....Very confusing..

    touristsis Visitor

      Hi, I'm seeing these errors under 7100, Utilities, Troubleshooting, Physical Interface.  It seems like the only way I can get the error to go away is set the Adtran Interface to Ethernet 10M/Half Duplex.  It does not make sense.  Can someone shed some light into it?  Is the Adtran Switch not auto negotiating.  I've look at the Polycom Phone Specs, it is 100M Full Duplex.

       

      There is a speed/duplex mismatch on port eth 0/14 with Polycom SoundPoint IP
      335.
        Local: 100M Full Duplex
        Neighbor: 10M Full Duplex
      There is a speed/duplex mismatch on port eth
      0/14 with Polycom SoundPoint IP 335.
