Object
The total number of packets received during this
sampling interval that were less than 64 octets in
length (excluding framing bits but including FCS
octets) had either a bad Frame Check Sequence (FCS)
with an integral number of octets (FCS Error) or a bad
FCS with a non-integral number of octets (Alignment
Error).
Note that it is entirely normal for etherHistoryFragments to
increment. This is because it counts both runts (which are
normal occurrences due to collisions) and noise hits.
