TopN Error Rates and TopN Discard Rates Blank

It is 99% likely that these are not missing but that there are no values for these types of things.  In network devices it is normal to see output discards and input errors, it is VERY uncommon to see input discards and output errors.  Back with older networking technologies like Frame Relay, X25, etc we used to see this happen and very rarely now we see it with bad transceivers and cables causing these values.
