UndersizePkts The total number of packets received that were less than 64 octets
long (excluding framing bits but including FCS octets) and were
otherwise well formed.
OversizePkts The total number of packets received that were longer than
1518 octets (excluding framing bits but including FCS octets) and
were otherwise well formed.
Fragments The total number of packets received 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 nonintegral number of octets
(Alignment Error). It is entirely normal for etherStatsFragments to
increment because it counts both runts (which are normal occurrences
due to collisions) and noise hits.
Collisions The best estimate of the total number of collisions on this Ethernet
segment.
Jabbers The total number of packets received 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). Jabber is defined as the condition where
any packet exceeds 20 ms. The allowed range to detect jabber is
between 20 ms and 150 ms.
1..64 The total number of packets (including bad packets) received that
were between 1 and 64 octets in length (excluding framing bits but
including FCS octets).
65..127 The total number of packets (including bad packets) received that
were between 65 and 127 octets in length (excluding framing bits but
including FCS octets).
128..255 The total number of packets (including bad packets) received that
were between 128 and 255 octets in length (excluding framing bits but
including FCS octets).
256..511 The total number of packets (including bad packets) received that
were between 256 and 511 octets in length (excluding framing bits but
including FCS octets).
511..1023 The total number of packets (including bad packets) received that
were between 511 and 1023 octets in length (excluding framing bits
but including FCS octets).
1024..1518 The total number of packets (including bad packets) received that
were between 1024 and 1518 octets in length (excluding framing bits
but including FCS octets).
