Table 179: IP Statistics Fields

Description
The total number of input datagrams received from interfaces, including those
received in error.
The number of input datagrams discarded due to errors in their IP headers, including
bad checksums, version number mismatch, other format errors, time-to-live exceeded,
errors discovered in processing their IP options, etc.
The number of input datagrams discarded because the IP address in their IP header's
destination field was not a valid address to be received at this entity. This count
includes invalid addresses (e.g., 0.0.0.0) and addresses of unsupported Classes (e.g.,
Class E). For entities which are not IP Gateways and therefore do not forward
datagrams, this counter includes datagrams discarded because the destination
address was not a local address.
The number of input datagrams for which this entity was not their final IP destination,
as a result of which an attempt was made to find a route to forward them to that final
destination. In entities which do not act as IP Gateways, this counter includes only
those packets which were Source-Routed via this entity, and the Source-Route option
processing was successful.
The number of locally-addressed datagrams received successfully but discarded
because of an unknown or unsupported protocol.
The number of input IP datagrams for which no problems were encountered to prevent
their continued processing, but which were discarded (e.g., for lack of buffer space).
Note that this counter does not include any datagrams discarded while awaiting re-
assembly.
The total number of input datagrams successfully delivered to IP user-protocols
(including ICMP).
The total number of IP datagrams which local IP user-protocols (including ICMP)
supplied to IP in requests for transmission. Note that this counter does not include any
datagrams counted in ipForwDatagrams.
The number of output IP datagrams for which no problem was encountered to prevent
their transmission to their destination, but which were discarded (e.g., for lack of buffer
space). Note that this counter would include datagrams counted in ipForwDatagrams
if any such packets met this (discretionary) discard criterion.
The number of IP datagrams discarded because no route could be found to transmit
them to their destination. Note that this counter includes any packets counted in
ipForwDatagrams which meet this `no-route' criterion. Note that this includes any
datagrams which a host cannot route because all of its default gateways are down.
The maximum number of seconds which received fragments are held while they are
awaiting reassembly at this entity.
The number of IP fragments received which needed to be reassembled at this entity.
The number of IP datagrams successfully re-assembled.
The number of failures detected by the IP re-assembly algorithm (for whatever reason:
timed out, errors, etc.). Note that this is not necessarily a count of discarded IP
fragments since some algorithms can lose track of the number of fragments by
combining them as they are received.
The number of IP datagrams that have been successfully fragmented at this entity.
The number of IP datagrams that have been discarded because they needed to be
fragmented at this entity but could not be, e.g., because their Don't Fragment flag was
set.
The number of IP datagram fragments that have been generated as a result of
fragmentation at this entity.
