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
buf
fer 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 buf
fer 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
.
