etherStatsUndersizePkts 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.
etherStatsFragments 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
FCS with an integral number of octets (FCS Error) or a bad FCS with a
nonintegral number of octets (Alignment Error).
Note It is entirely normal for etherStatsFragments to increment. This is
because it counts both runts (which are normal occurrences due to
collisions) and noise hits.
etherStatsPkts64Octets The total number of packets (including bad packets) received that were
64 octets in length (excluding framing bits but including FCS octets).
etherStatsPkts65to127
Octets
The total number of packets (including bad packets) received that were
between 65 and 127 octets in length inclusive (excluding framing bits but
including FCS octets).
etherStatsPkts128to255
Octets
The total number of packets (including bad packets) received that were
between 128 and 255 octets in length inclusive (excluding framing bits but
including FCS octets).
etherStatsPkts256to511
Octets
The total number of packets (including bad packets) received that were
between 256 and 511 octets in length inclusive (excluding framing bits but
including FCS octets).
etherStatsPkts512to1023
Octets
The total number of packets (including bad packets) received that were
between 512 and 1023 octets in length inclusive (excluding framing bits
but including FCS octets).
etherStatsPkts1024to1518
Octets
The total number of packets (including bad packets) received that were
between 1024 and 1518 octets in length inclusive (excluding framing bits
but including FCS octets).
etherStatsOversizePkts The total number of packets received that were longer than 1518 octets
(excluding framing bits, but including FCS octets) and were otherwise
well formed. Note that for tagged interfaces, this number becomes 1522
bytes.
etherStatsJabbers The total number of packets received that were longer than 1518 octets
(excluding framing bits, but including FCS octets), and had either a bad
FCS with an integral number of octets (FCS Error) or a bad FCS with a
nonintegral number of octets (Alignment Error).
etherStatsOctets The total number of octets of data (including those in bad packets)
received on the network (excluding framing bits but including FCS octets
etherStatsCRCAlign
Errors
The total number of packets received that had a length (excluding framing
bits, but including FCS octets) of between 64 and 1518 octets, inclusive,
but had either a bad FCS with an integral number of octets (FCS Error) or
a bad FCS with a nonintegral number of octets (Alignment Error).
