How to discover CRC Error and input error

[Wlewx11]

as title, any idea or any freeware can be share to detect the cisco CRC error/ input error. Even amber light in control panel? I talking if over 100 units of 2950 serial switches was located in difference building.

normally, if syslog configured, switches will send to syslog server a message indicating errors in one particular port

Yes, you r right. But normally the syslog only show which up/down alert just indicate particular network connect and disconnecte

Any other pro-active way to monitor the CRC error?

no, syslog can send you errors too. below is an example from MY syslog in OUR network

Yes, i do have the Kiwi syslog and it can send me the Daily Syslog statistics as well.

But it can't show me any CRC alert (it dont have any up/down alert)

It isn't freeware, but it can help you get more insight on the CRC-errors in your network ; Cacti!
