ipInUnknownProtos
The number of locally addressed datagrams received successfully but discarded because of an
unknown or unsupported protocol.
ipInDiscards
The number of input IP datagrams for which no problems were encountered that would 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.
ipInDelivers
The total number of input datagrams successfully delivered to IP device-protocols (including
ICMP).
ipOutRequests
The total number of IP datagrams which local IP device-protocols (including ICMP) supplied to IP
in requests for transmission.
ipOutDiscards
The number of output IP datagrams for which no problem was encountered that would 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.
ipOutNoRoutes
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 that meet
this “no-route” criterion. Note that this includes any datagrams that a host cannot route because all
of its default gateways are down.
ipReasmTimeout
The maximum number of seconds that received fragments are held while they are awaiting
reassembly at this system.
ipReasmReqds
The number of IP fragments received which needed to be reassembled at this system.
ipReasmOKs
The number of IP datagrams successfully reassembled.
ipReasmFails
The number of failures detected by the IP reassembly algorithm (for whatever reason: timed out,
errors, etc.). Note that this is not necessarily a count of discarded IP fragments since some
algorithms (notably the algorithm in RFC 815) can lose track of the number of fragments by
combining them as they are received.
ipFragOKs
The number of IP datagrams that have been successfully fragmented at this system.
ipFragFails
The number of IP datagrams that have been discarded because they needed to be fragmented at
this system but could not be, for example, because their “Don't Fragment” flag was set.
