Statistic
Description
etherStatsDropEvents
The total number of packets received that were dropped because
of system resource constraints.
etherStatsOctets
The total number of octets of data (including those in bad
packets) received on the network (excluding framing bits but
including FCS octets).
etherStatsPkts
The total number of packets (including bad packets, broadcast
packets, and multicast packets) received.
etherStatsBroadcastPkts
The total number of good packets received that were directed to
the broadcast address.
etherStatsMulticastPkts
The total number of good packets received that were directed to
a multicast address.
etherStatsCRCAlignErrors
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 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).
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.
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.
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 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).
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 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).
etherStatsCollisions
The best estimate of the total number of collisions on this Ethernet
segment.
