EtherStats CRC Align Errors: The total number of packets
received that had a length (excluding framing bits, but including
FCS octets) between 64 and 1518 octets, 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).
EtherStats Undersize Pkts: 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.
EtherStats Oversize Pkts: The total number of packets
received that were longer than 1518 octets (excluding framing
bits, but including FCS octets) and were otherwise well formed.
EtherStats 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 non-integral number of octets (Alignment
Error). NOTE: this is entirely normal for etherStatsFragments
to increment. This is because it counts both runts (which are
normal occurrences due to collisions) and noise hits.
EtherStats 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).
EtherStats Collisions: The best estimate of the total number of
collisions on this Ethernet segment. The value returned will
depend on the location of the RMON probe.
Pkts 64 Octets: The total number of packets (including bad
packets) received that were 64 octets in length (excluding
framing bits, but including FCS octets).
