1180 RMON Commands
Undersize The number of packets received during this sampling interval that were
less than 64 octets long (excluding framing bits but including FCS
octets) and were otherwise well formed.
Oversize The number of packets received during this sampling interval that were
longer than 1518 octets (excluding framing bits but including FCS
octets) but were otherwise well formed.
Fragments 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 (AlignmentError). It is normal for
etherHistoryFragments to increment because it counts both runts
(which are normal occurrences due to collisions) and noise hits.
Jabbers The number of packets received during this sampling interval that were
longer than 1518 octets (excluding framing bits but including FCS
octets), and 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).
Dropped The total number of events in which packets were dropped by the probe
due to lack of resources during this sampling interval. This number is
not necessarily the number of packets dropped. It is just the number of
times this condition has been detected.
Collisions The best estimate of the total number of collisions on this Ethernet
segment during this sampling interval.
