0 output errors, 0 collisions, 0 interface resets
0 babbles, 0 late collision, 0 deferred
0 lost carrier, 0 no carrier
0 output buffer failures, 0 output buffers swapped out
Start troubleshooting the problem by checking the physical layer (Plugs, Jacks, Cables). Replace them with known working equipment.
Once you have traced the line from your Cisco to each other end (through to ISP, and to network switch), then reset your error counters, by restarting the cisco.
Check the ethernet interfaces on the network switch and the Cisco. Make sure they are both set to Autonegotiate or both set to the same settings like 100mbs Full-duplex. If they are not communicating the same way lots of errors will be generated.
