IP Statistics
The statistics reported on the IP Statistics screen are as specified in RFC 1213.

Description
IpInReceives
The total number of input datagrams received from interfaces, including
those received in error.
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.
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.

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.
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.

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.
