Troubleshooting Ethernet and Fragmentation Issues
... twisted-pair, Ethernet networks. A duplex mismatch is when one port on an Ethernet link is operating at half-duplex while the other port is operating at full-duplex. The result of a duplex mismatch can be extremely slow performance, intermittent connectivity problems and/or a complete loss of connec ...
