IP Forward
Datagrams
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.
Note: This is routed by the supervisor in the
software.
IP In Unknown
Protocols
Number of input datagrams discarded due to
errors in their IP headers. Such errors may
include bad checksums, version number
mismatches, other format errors, time-to-live
exceeded, errors discovered in processing their
IP options.
IP In Discards Number of input IP datagrams for which no
problems were encountered to prevent their
continued processing, but which were discarded
(for example, for lack of buffer space).
Note: This counter does not include any
datagrams discarded while awaiting re-
assembly.
IP In Delivers Total number of input datagrams successfully
delivered to IP user-protocols (including ICMP).
IP Out Requests Total number of IP datagrams that local IP user-
protocols (including ICMP) supplied to IP in
requests for transmission.
Note: This counter does not include any
datagrams counted in ipForwDatagrams.
IP Out Discards Number of output IP datagrams for which no
problem was encountered to prevent their
transmission to their destination, but were
discarded (for example, for lack of buffer space).
Note that this counter includes datagrams
counted in ipForwDatagrams if any such
packets met this (discretionary) discard
criterion.
