Table 68. IP statistics
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, and so on.
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 (such as
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.
