IpInAddrErrors The number of input datagrams discarded because the IP address in their
IP header's destination field was not a valid address to be received at this
entity. This count includes invalid addresses (for example, 0.0.0.0) and
addresses of unsupported classes (such as., Class E). For entities that are
not IP gateways and therefore do not forward datagrams, this counter
includes datagrams discarded because the destination address was not a
local address.
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 which were
discarded for reasons such as 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 needed to be 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, etc).
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.
