Viewing IP Group Statistics
datagrams, this counter includes datagrams discarded
because the destination address was not a local address.
This field displays the ipInAddrErrors.
Forwarded The number of received 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 successfully via this entity,
and the Source-Route option processing was successful.
This field displays the ipForwDatagrams.
Unknown Protocol The number of locally-addressed datagrams received
successfully but discarded because of an unknown or
unsupported protocol. This field displays the
ipInUnknownProtos.
Discarded 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). This counter does not include any
datagrams discarded while awaiting reassembly. This
field displays the ipInDiscards.
Delivered The total number of input IP datagrams success fu lly
delivered to IP user-protocols (including ICMP),
according to the ipInDelivers.
Transmitted Datagrams
Total The total number of input datagrams successfully
delivered to IP user-protocols (including ICMP),
according to the ipOutRequests.
Discarded 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). This counter would include
datagrams counted in ipForwDatagrams if any such
packets met this (discretionary) discard criterion. This
field displays the ipOutDiscards.
This counter indicates that the device is tossing away
valid datagrams, indicating that the destination network
is seriously overloaded, or that the device itself is
experiencing problems (evidenced by the failing
read-write buffer). If the device discards a datagram, it
occurs after the device increments the Fwd Datagrams
counter and passes the datagram to the transmit buffer.
