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 reassembled.
IpReasmFails
The number of failures detected by the IP reassembly 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.
IcmpInMsgs
The total number of ICMP messages that the entity received. This counter
includes all those counted by icmpInErrors.
IcmpInErrors
The number of ICMP messages that the entity received but determined as
having ICMP-specific errors (bad ICMP checksums, bad length, and so on).
IcmpInDestUnreachs
The number of ICMP destination unreachable messages received.
