so many crc errors and overrun on 3548

Hi,guys

I have some 3548 switch,and there are many errors over a short period of time on each 3548. I tried change cable and duplex and speed,but nothing is changed.Does anyone encounted same problem? Are there some documents which describe interop between NIC and switch OR are there some bug of 3548? Cable length is < 10 Meter.

Any comments are appreciated!
