Description
The total number of input datagrams received from
interfaces, including those received in error.
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.
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.
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.
The number of locally-addressed datagrams
received successfully but discarded because of an
unknown or unsupported protocol.
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.
The total number of input datagrams successfully
delivered to IP user-protocols (including ICMP).
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.
