Packet Errors If you have a large amount of alignment errors, FCS errors, or late collisions, this may indicate:
Duplex mismatch Bad NICs Cable problems (causing mangled packets, flapping ports, and so on) For more information on duplex mismatch errors, see Configuring and Troubleshooting Ethernet 10/100Mb Half/Full Duplex Auto-Negotiation. The most common issue with speed/duplex is that customers manually set the speed/duplex on the switch, but not on the workstation/server. Auto speed/duplex on one side and 100/Full-duplex on the other side is a misconfiguration and will result in a duplex mismtach. Larry Letterman Cisco Systems Sim, CT (Chee Tong) wrote: >Hi..
