Please log in for more thread options "8059 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored" No no overruns, CRCs errors, etc, so what other causes are there for these errors. Both side are half-duplex.

Please log in for more thread options If the sender of a frame detects a collision, it sends a abort sequence to the ethernet. This is an input error, but non of the specified error conditions, because it's a valid abort of transfer. | ||||||||||||||||

Hmm, never heard of that one?

Have a look at sh int FastEthernet0/5 counters sh int FastEthernet0/5 counters error sh int FastEthernet0/5 counters detailed Possibly non performance impacting bug? Always worth checking the snmp counters to see if there is anything there that is not in the sh int counters. The error rate is not that high 1/50,000 so not worth getting into a huge lather about. "Last clearing of "show interface" counters never " These errors may be historic. | ||||||||||||||||
