"You there, What do you know about this?" - What did I do now? However 8B/10B has some great error detection capabilities whose usefulness cannot be ignored at a time when the HSSG will strongly consider other coding alternatives. 8B/10B-based links provide a very efficient If the inbound errors are having an actual impactI've tried clearing counters to get an idea of whether or not these inbound errors are the result of some PMTU discovery firing

Crc Errors On Network Interface Where the values do not match, there is an FCS error.
In addition, so long as continuously-enabled code-group alignment (hot sync) is not employed, a misaligned comma (present in Idles and Config) will always generate a code violation. I noticed on my controller that I'm taking a fairly large amount of inbound/crc/giant errors. One simple way to do this is to count the first error and then ignore errors for a specific time interval. http://networkengineering.stackexchange.com/questions/1467/what-is-the-meaning-of-the-crc-counter-on-a-cisco-device To troubleshoot dirty optics, clean the optics at both ends, as described in Cleaning and Inspecting Optical Fibres.
