Field Description
Octets The total number of octets of data (including those in bad
packets) received on the network (excluding framing bits but
including FCS octets). You can use this object as a reasonable
estimate of Ethernet utilization. For greater precision, sample
the etherStatsPkts and etherStatsOctets objects before and
after a common interval.
Pkts The total number of packets (including bad packets, broadcast
packets, and multicast packets) received.
BroadcastPk
ts
The total number of good packets received that were directed
to the broadcast address. Note that this does not include
multicast packets.
MulticastPkt
s
The total number of good packets received that were directed
to a multicast address. Note that this number does not include
packets directed to the broadcast address.
CRCAlignErr
ors
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 nonintegral number of octets
(Alignment Error).
UndersizePk
ts
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.
OversizePkt
s
The total number of packets received that were longer than
1518 octets (excluding framing bits but including FCS octets),
and were otherwise well-formed.
