Table 270: 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 (for example, 0.0.0.0) and addresses of
unsupported Classes (for example, 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.
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 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 (for example, 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
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 (for
example, 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.
