sampling interval that were longer than 1518
octets (excluding framing bits but including FCS
octets) but were otherwise well formed.
etherHistoryFragments 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).
etherHistoryJabbers The number of packets received during this
sampling interval that were longer than 1518
octets (excluding framing bits but including FCS
