Most of our servers that are connected to a Cisco 3548 Switch are seeing extreme amounts of CRC errors, but I am not seeing any errors on the interfaces or uplink interfaces of this switch. Installed a new switch and moved some of the servers to this switch and the problem was fixed. I don't understand why I didn't see these CRC errors on the old switch. Any Ideas!!
Thanks in Advance

Hi -
I presume that you checked ALL the connected ports settings, i.e. that the connected ports to your servers from the switch are all running on correct speed, either 100full, half, or auto, and that the server NIC's are set to the correct speed as the switch port(s) ??
Hope this helps --

All Servers are connected 100Full and the swtch is configured for 100Full. These servers have been in operation for over 1 year with no problems. The NIC's are all IBM.

Have you try to set duplex and speed manually on switch? Duplex and speed auto sensing arent really reliable on Cisco switches.
And also, did you happen to have Intel NIC(eepro100) on your server?
There was some issue between Intel NIC and Cat switch..
Good luck
