Counter
Definition:
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.
Access:
read-only.
Status:
mandatory.

ipInUnknownProtos { ip 7 }
Syntax:
Counter
IETF SNMP Working Group [Page 32]
RFC 1158 MIB II May 1990
Definition:
The number of locally-addressed datagrams received
successfully but discarded because of an unknown or
unsupported protocol.
Access:
read-only.
Status:
mandatory.
OBJECT:
-------
ipInDiscards { ip 8 }
Syntax:
Counter
Definition:
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.
Access:
read-only.
Status:
mandatory.
OBJECT:
-------
ipInDelivers { ip 9 }
Syntax:
Counter
Definition:
The total number of input datagrams successfully
delivered to IP user-protocols (including ICMP).
Access:
read-only.
IETF SNMP Working Group [Page 33]
RFC 1158 MIB II May 1990
Status:
mandatory.
OBJECT:
-------
ipOutRequests { ip 10 }
Syntax:
Counter
Definition:
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.
Access:
read-only.
Status:
mandatory.
OBJECT:
ipOutDiscards { ip 11 }
Syntax:
Counter
Definition:
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.
Access:
read-only.
Status:
mandatory.
OBJECT:
-------
ipOutNoRoutes { ip 12 }
IETF SNMP Working Group [Page 34]
RFC 1158 MIB II May 1990
Syntax:
Counter
Definition:
The number of IP datagrams discarded because no route
could be found to transmit them to their destination.
Note that this counter includes any packets counted in
ipForwDatagrams which meet this "no-route" criterion.
Note that this includes any datagarms which a host cannot
route because all of its default gateways are down.
Access:
read-only.
Status:
mandatory.
OBJECT:
-------
ipReasmTimeout { ip 13 }
Syntax:
INTEGER
Definition:
The maximum number of seconds which received fragments
are held while they are awaiting reassembly at this
entity.
Access:
read-only.
Status:
mandatory.
OBJECT:
-------
ipReasmReqds { ip 14 }
Syntax:
Counter
Definition:
The number of IP fragments received which needed to be
reassembled at this entity.
IETF SNMP Working Group [Page 35]
RFC 1158 MIB II May 1990
Access:
read-only.
Status:
mandatory.
OBJECT:
-------
ipReasmOKs { ip 15 }
Syntax:
Counter
Definition:
The number of IP datagrams successfully re-assembled.
Access:
read-only.
Status:
mandatory.
OBJECT:
-------
ipReasmFails { ip 16 }
Syntax:
Counter
Definition:
The number of failures detected by the IP re-assembly
algorithm (for whatever reason: timed out, errors, etc).
Note that this is not necessarily a count of discarded IP
fragments since some algorithms (notably the algorithm in
RFC 815) can lose track of the number of fragments by
combining them as they are received.
Access:
read-only.
Status:
mandatory.
IETF SNMP Working Group [Page 36]
RFC 1158 MIB II May 1990
OBJECT:
-------
ipFragOKs { ip 17 }
Syntax:
Counter
Definition:
The number of IP datagrams that have been successfully
fragmented at this entity.
Access:
read-only.
Status:
mandatory.
OBJECT:
-------
ipFragFails { ip 18 }
Syntax:
Counter
Definition:
The number of IP datagrams that have been discarded
because they needed to be fragmented at this entity but
could not be, e.g., because their "Don't Fragment" flag
was set.
Access:
read-only.
Status:
mandatory.
OBJECT:
-------
ipFragCreates { ip 19 }
Syntax:
Counter
Definition:
The number of IP datagram fragments that have been
generated as a result of fragmentation at this entity.

Status:

5.4.1. The IP Address table
The Ip Address table contains this entity's IP addressing
information.
OBJECT:
-------
ipAddrTable { ip 20 }
Syntax:
SEQUENCE OF IpAddrEntry
Definition:
The table of addressing information relevant to this
entity's IP addresses.
Access:
read-only.
Status:
mandatory.
OBJECT:
-------
ipAddrEntry { ipAddrTable 1 }
Syntax:
IpAddrEntry ::= SEQUENCE {
ipAdEntAddr
IpAddress,
ipAdEntIfIndex
INTEGER,
ipAdEntNetMask
IpAddress,
ipAdEntBcastAddr
INTEGER,
ipAdEntReasmMaxSize
INTEGER (0..65535)

addresses.
Access:

ipAdEntAddr { ipAddrEntry 1 }
Syntax:
IpAddress
Definition:
The IP address to which this entry's addressing
information pertains.

OBJECT:
-------
ipAdEntIfIndex { ipAddrEntry 2 }
Syntax:

The index value which uniquely identifies the interface
to which this entry is applicable. The interface
identified by a particular value of this index is the
same interface as identified by the same value of
ifIndex.
