4.6.1.2 IP Statistics
The statistics reported on this screen are as specified in RFC 1213.
Non-Configurable Data
。 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.
。 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 will include 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).
