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 which do
not act as IP routers, this counter will include only those packets
which were Source-Routed via this entity, and the Source-route
option processing was successful.
ipFragCreates
The number of IP datagram fragments that have been generated as
a result of fragmentation at this entity.
ipFragFails
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.
ipFragOKs
The number of IP datagrams that have been successfully
fragmented at this entity.
ipInAddrErrors
The number of input datagrams discarded because the IP address
in their header's destination field was not a valid address to be
received at this entity. This count includes invalid addresses and
addresses of unsupported Classes. For entities which are not
IP routers and therefore do not forward datagrams, this counter
includes datagrams discarded because the destination address was
not a local address.
ipInDelivers
The total number of input datagrams successfully delivered to IP
user-protocols (including ICMP)
ipInDiscards
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 reassembly
ipInHdrErrors
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.
ipInReceives
The total number of input datagrams received from interfaces,
including those received in error.
ipInUnknownProtos
The number of locally addressed datagrams received successfully
but discarded because of an unknown or unsupported protocol.
ipOutDiscards
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.
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 which meet this
`no-route' criterion. Note that this includes any datagrams which a
host cannot route because all of its default routers are down.
ipOutRequests
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.
ipRasmReqds
The number of IP fragments received which needed to be
reassembled at this entity.
ipReasmFails
The number of IP datagrams successfully reassembled.
