Multicast Number of good packets received during this sampling interval that
were directed to a multicast address. This number does not include
packets addressed to the broadcast address.
Utilization Best estimate of the mean physical layer network utilization on this
interface during this sampling interval, in hundredths of a percent.
CRC Align Number of packets received during this sampling interval that had a
length (excluding framing bits but including FCS octets) between 64
and 1518 octets, inclusive, but 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).
Undersize 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 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 Total number of packets received during this sampling interval that
were less than 64 octets in length (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). It is normal for
etherHistoryFragments to increment because it counts both runts
(which are normal occurrences due to collisions) and noise hits.
Jabbers 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 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 the number of
times this condition has been detected.
Collisions Best estimate of the total number of collisions on this Ethernet
segment during this sampling interval.
