Table 62. Routing IP Statistics Fields
Field
Description
IpInReceives
The total number of input datagrams received from interfaces, including those received in
error.
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.
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 (e.g., 0.0.0.0) and addresses of unsupported Classes (e.g., Class E). For
entities which are not IP Gateways and therefore do not forward datagrams, this counter
includes datagrams discarded because the destination address was not a local address.
IpFwdDatagrams
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 Gateways, this counter includes only those packets which
were Source-Routed via 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 (e.g., for lack of buffer space). Note that 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 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.
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 gateways are down.
IpReasmTimeout
The maximum number of seconds which received fragments are held while they are awaiting
reassembly at this entity.
IpReasmReqds
The number of IP fragments received which needed to be 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, etc.). Note that 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 have been successfully fragmented 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.
IpFragCreates
The number of IP datagram fragments that have been generated as a result of fragmentation
at this entity.
IpRoutingDiscards
The number of routing entries which were chosen to be discarded even though they are valid.
One possible reason for discarding such an entry could be to free-up buffer space for other
routing entries.
IcmpInMsgs
The total number of ICMP messages which the entity received. Note that this counter includes
all those counted by icmpInErrors.
