IpForwDatagrams 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 that do not act as IP
gateways, this counter includes only those packets that were
source-routed through this entity, and the source-route option
processing was successful.
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 to prevent their continued processing, but that were
discarded (for lack of buffer space). This counter does not include any
datagrams discarded while awaiting re-assembly.
IpInDelivers The total number of input datagrams successfully delivered to IP user
protocols (including ICMP).
IpOutRequests The total number of IP datagrams that local IP user protocols (including
ICMP) supplied to IP in requests for transmission. This counter does
not include any datagrams counted in ipForwDatagrams.
IpOutDiscards The number of output IP datagrams for which no problem was
encountered to prevent their transmission to their destination, but that
were discarded for reasons such as lack of buffer space. 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. This counter includes any
packets counted in ipForwDatagrams that meet this no-route criterion.
This includes any datagrams that a host cannot route because all of its
default gateways are down.
IpReasmTimeout The maximum number of seconds for which received fragments are
held while they are awaiting reassembly at this entity.
IpReasmReqds The number of IP fragments received that were reassembled at this
entity.
IpReasmOKs The number of IP datagrams successfully re-assembled.
IpReasmFails The number of failures detected by the IP re-assembly algorithm (for
whatever reason: timed out, errors, and so on). 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.
IpFragOKs The number of IP datagrams that were fragmented at this entity.
IpFragFails The number of IP datagrams that were discarded because they needed
to be fragmented at this entity but could not be, for reasons such as
their Don't Fragment flag was set.
IpFragCreates The number of IP datagram fragments that were generated as a result
of fragmentation at this entity.
