ipDefaultTTL (2)
The default value inserted into the Time-To-Live field of the IP header of datagrams originated
at this entity, whenever a TTL value is not supplied by the transport layer protocol.
ipInReceives (3)
The total number of input datagrams received from interfaces, including those received in error.
ipInHdrErrors (4)
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 (5)
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 (6)
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 (7)
The number of locally-addressed datagrams received successfully but discarded because of an
unknown or unsupported protocol.
ipInDiscards (8)
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 (9)
The total number of input datagrams successfully delivered to IP user-protocols (including
ICMP).
ipOutRequests (10)
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.
ipOutDiscards (11)
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.
