Field Description
Utilization 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 (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.
