Right, but don't forget that this number (whatever it is) is a rate.  Unless you 
have a really bad network connection, I doubt you'll get a meaningful number.
If you have 300 CRC errors in a 5 minute period, you'll only have 1 in the log 
file.  Is this what you intend?  Or, do you have links that are far above 300 
errors per 5 minute window?
