2950 - input errors

I have 4 2950 in a cluster and I'm currently checking out a web server. I configured fast etherchannel with port group command, did the same on the server. Well, I'm getting errors and I was wondering, is ther anything I can do about these errors? The switches are running at 23% CPU, is that average?

Re: 2950 - input errors

Hi,

Looks like this is a software error. Try checking the Network Card Driver for a newer version. Another thing make sure that the Duplex/Speed is set hard coded on boths sides. If Problems occur still, even after software update of NIC, take it down half a notch to half duplex and see if the rate lowers or stops. 23% is ok for the utilization.

Regards,

Corey

Re: 2950 - input errors

Yap, that web server had old crapy windows drivers. So, input errors means OS problems = drivers?

Re: 2950 - input errors

try connecting some other PC's to the same port.

Whether the errors are seen in all the ports?

Also try changing the cable.
