I wanna track CRC Error..Understand I can use MIBs object? But any links to point me to the config? Or any advises on this?
I am not sure CRC error is similar to packets errors.
You can use CiscoWorks LMS to send notification if line error rate is greater than certain %(1% is default).
I do not see any point to track the exact figure as it is ever growing if I remember correctly.
Ask you customer what will they do with the figures? Most important thing is to get alerted when error rate is high not because of 1 crc error out of millions of packets.
Plz rate if helpful.
