Table 94. IP statistics information (Continued)
Description Field
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 (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.
IpInAddrErrors
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.
IpForwDatagrams
The number of locally addressed datagrams received successfully but
discarded because of an unknown or unsupported protocol.
IpInUnknownProtos
The number of input IP datagrams for which no problems were
encountered to prevent their continued processing, but that were
discarded (for lack of buffer space). This counter does not include any
datagrams discarded while awaiting reassembly.
IpInDiscards
The total number of input datagrams successfully delivered to IP user
protocols (including ICMP).
IpInDelivers
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.
IpOutRequests
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 buffer space. This counter
would include datagrams counted in ipForwDatagrams if any such packets
met this (discretionary) discard criterion.
IpOutDiscards
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.
