15.6.3 ML-Series Ethernet Card Performance Monitoring Parameters
dot3StatsAlignmentErrors A count of frames received on a particular interface that are not an integral
number of octets in length and do not pass the FCS check.
dot3StatsFCSErrors A count of frames received on a particular interface that are an integral
number of octets in length but do not pass the FCS check.
dot3StatsSingleCollisionF
rames
1
A count of successfully transmitted frames on a particular interface for
which transmission is inhibited by exactly on collision.
dot3StatsFrameTooLong
1
A count of frames received on a particular interface that exceed the
maximum permitted frame size.
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. Note that for tagged interfaces, this number becomes 1522
bytes.
etherStatsFragments
1
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 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
1
The total number of packets (including bad packets) received that were 64
octets in length (excluding framing bits but including FCS octets).
etherStatsPkts65to127Oct
ets
1
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).
etherStatsPkts128to255Oc
tets
1
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).
etherStatsPkts256to511Oc
tets
1
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).
etherStatsPkts512to1023O
ctets
1
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
1
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).
etherStatsBroadcastPkts
1
The total number of good packets received that were directed to the
broadcast address. Note that this does not include multicast packets.
