2950-incrementing ignored errors

I am seeing ignored errors incrementing on almost every interface, in almost every Cat2950 in my network. I have about 24-2950s, that are uplinked to 2-2948G. Right now the majority of all of these switches belong to the same vlan. I am not seeing any other errors, other than these ignored errors, including no buffer errors. I have also noticed that several of our customers have been complaining of slow ftp transers lately too, would this have anything to do with it? If someone could point me in the right direction as to where I can go, or help me with suggestions of how to fix this. Any help appreciated!!!

Re: 2950-incrementing ignored errors

What software version are you running? Take a look at

http://www.cisco.com/cgi-bin/bugtool/onebug.pl?bugid=CSCdw48441

There is also another open bug

http://www.cisco.com/cgi-bin/bugtool/onebug.pl?bugid=CSCdz59272

I suggest that you open a TAC case as well and provide all the info to the TAC Engineer

Re: 2950-incrementing ignored errors

One thing i noticed in your configuration is that you use auto-neg for speed and duplex, if you instead configure those values with "hard values" the swiches at least don't have to negogiate speed and duplex with each other.

Maybe this can help you.
