Field Description
Time Date and Time the entry is recorded.
Octets The total number of octets of data (including those in bad packets) received on the network
(excluding framing bits but including FCS octets).
Packets The number of packets (including bad packets) received during this sampling interval.
Broadcast The number of good packets received during this sampling interval that were directed to the
Broadcast address.
Multicast The 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.
Util The best estimate of the mean physical layer network utilization on this interface during this
sampling interval, in hundredths of a percent.
CRC Align The 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 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 (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 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).
