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 go od packets rec eived duri ng this samp ling interv al that
were directed to the Broadcas t address.
Multicast The number of good packet s received d uring this s ampling int erval that
were directed to a Multicast address. This number does not include
packets addressed to the Broadcast address.
% 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) wit h an int egral n umber o f octet s (FCS E rror) o r a bad FCS wit h
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 (AlignmentError). It is normal for
etherHistoryFragments to increment because it counts both runts
(which are normal occurrences due to collisions) and noise hits.
