input and crc errors on ws-3750-48ts-s

I am in the process of moving connections off of a Cat 4006 onto a stack of 3750s.

On the 4006, I see no errors on the show interface command. I move the cable ( same exact cable ) from the 4006 to the 3750 and the port gets CRC and input errors.

The ports are hard coded 100/Full on both switches. The devices are coded 100/Full on the Nic.

I had this type of problem with the 2924 series years ago. At that time, Cisco's response was that the Nic cards were not compatible with the switch.

Are there Nic cards that the 3750's do not work well with?

The only other commands that I have set on the ports are spanningtree portfast and bpdugaurd enable.

If these are older machines you may have to get updated drivers for the nics . Also check the bug troubleshooter for an bugs for the 3750 code you are running . This page may also help
