Port Statistic Description
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 non-integral number of octets (Alignment Error). It is normal for
StatsFragments to increment because both runts, which are normal
occurrences due to collisions, and noise hits are counted.
EtherStatsPkts64Octets The total number of packets (including bad packets) received that were 64
octets in length (excluding framing bits, but including FCS octets).
EtherStatsPkts65to127Octets 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).
EtherStatsPkts128to255Octets 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).
EtherStatsPkts256to511Octets 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).
EtherStatsPkts512to1023Octets 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).
EtherStatsPkts1024to1518Octets 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.
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
non-integral number of octets (Alignment Error). This definition of jabber is
different than the definition in IEEE-802.3 section 8.2.1.5 (10BASE5) and
section 10.3.1.4 (10BASE2). These documents define jabber as the
condition where any packet exceeds 20 ms. The allowed range to detect
jabber is between 20 ms and 150 ms.
EtherStatsOctets The total number of octets of data (including those in bad packets)
received on the FCS octets). This object can be used as a reasonable
estimate of Ethernet utilization. If greater precision is required, the
StatsPkts and StatsOctets objects should be sampled before and after a
common interval. The differences in the sampled values are Pkts and
Octets, respectively, and the number of seconds in the interval is Interval.
These values are used to calculate the Utilization as follows: Utilization =
[(Pkts * (9.6 + 6.4) + (Octets * .8)) / (Interval * 10,000)]. The result of this
equation is the value Utilization which is the percent utilization of the
Ethernet segment on a scale of 0 to 100 percent.
EtherStatsPkts The total number of packets (including bad packets, broadcast packets,
and multicast packets) received.
