Port Statistic Description
IpInReceives
The total number of input datagrams received from interfaces, including
those received in error
IpInHdrErrors
The number of input datagrams discarded because of errors in their IP
headers, including bad checksums, version number mismatch, other
format errors, time-to-live exceeded, and errors discovered in processing
their IP options
IpForwDatagrams
The number of input datagrams for which this entity was not their final IP
destination. As a result, an attempt was made to find a route to forward
them to that final destination. In entities that do not act as IP Gateways, this
counter includes only those packets that were Source-Routed via this
entity, and the ones for which Source-Route option processing was
successful.
IpInDiscards
The number of input IP datagrams for which no problems were
encountered to prevent their continued processing, but which were
discarded (possibly for lack of buffer space). This counter does not include
any datagrams discarded while awaiting re-assembly.
Dot1dBasePortDelayExceeded
Discards
The number of frames discarded by this port because of excessive transit
delay through the bridge. It is incremented by both transparent and source
route bridges.
Dot1dBasePortMtuExceeded
Discards
The number of frames discarded by this port because of an excessive size.
It is incremented by both transparent and source route bridges.
Dot1dBasePortInFrames
The number of frames that have been received by this port from its
segment. A frame received on the interface corresponding to this port is
only counted by this object only if it is for a protocol being processed by
the local bridging function, including bridge management frames.
Dot1dBasePortOutFrames
The number of frames that have been transmitted by this port to its
segment. A frame transmitted on the interface corresponding to this port is
counted by this object only if the frame is for a protocol being processed
by the local bridging function, including bridge management frames.
Dot1dBasePortInDiscards
Count of valid frames received that were discarded (filtered) by the
Forwarding Process
EtherStatsDropEvents
The total number of events in which packets were dropped by the probe
because of lack of resources. This number is not necessarily the number of
packets dropped, but is the number of times this condition has been
detected.
EtherStatsMulticastPkts
The total number of good packets received that were directed to a
multicast address. This number does not include packets directed to the
broadcast address.
EtherStatsBroadcastPkts
The total number of good packets received that were directed to the
broadcast address. This number does not include multicast packets.
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
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 caused by 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).
