CRCAlignment Errors Numberof packets received during this sampling interval that
hada length (excluding fram ing bits but including FCS octets)
between64 and 1518 oc tets, inclusive, but had either a bad
FrameCheck Sequence (FCS) with an integral number of
octets(FCS Error) or a ba d FCS with a non-integral number of
octets(Alignment Error).
UndersizePac kets Numberof packets received during this sampling interval that
wereless than 64 octets long (excluding framing bits but
includingFCS octets) butwere otherwise well formed.
OversizePac kets Numberof packets received during this sampling interval that
werelonger than 1518 octets (excluding framing bits but
includingFCS octets) butwere otherwise well formed.
Fragments Totalnumber of packets received during this sampling interval
thatwere less than 64 octets in length (excluding framing bits
butincluding FCS octets), had eithera bad Frame Ch eck
Sequence(FCS) with an integral number of octets (FCS Error)
ora bad FCS witha non-integral number of oct ets (Alignment
Error).Note that it is entirely normal for etherHistoryFragments
toincrement. This is because it counts both runts (which are
normaloccurrences du e to collisions) and noise hits.
Jabbers Numberof packets received during this sampling interval that
werelonger than 1518 octets (excluding framing bits but
includingFCS octets), and hadeither a bad F rame Check
Sequence(FCS) with an integral number of octets (FCS Error)
ora bad FCS witha non-integral number of oct ets (Alignment
Error).
Collisions Bestestimate of the totalnumber of collisions on thisEthernet
segmentduring this sampling interval.
Utilization Bestestimate of the mean physical layer network utilization on
thisinterface during this sampling interval, in hund redths of a
percent.
