SNMPv2 Management Information Base
for the Internet Protocol using SMIv2
Status of this Memo
This document specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the "Internet
Official Protocol Standards" (STD 1) for the standardization state
and status of this protocol. Distribution of this memo is unlimited.
IESG Note:
The IP, UDP, and TCP MIB modules currently support only IPv4. These
three modules use the IpAddress type defined as an OCTET STRING of
length 4 to represent the IPv4 32-bit internet addresses. (See RFC
1902, SMI for SNMPv2.) They do not support the new 128-bit IPv6
internet addresses.

1. Introduction
A management system contains: several (potentially many) nodes, each
with a processing entity, termed an agent, which has access to
management instrumentation; at least one management station; and, a
management protocol, used to convey management information between
the agents and management stations. Operations of the protocol are
carried out under an administrative framework which defines
authentication, authorization, access control, and privacy policies.
McCloghrie Standards Track [Page 1]
RFC 2011 SNMPv2 MIB for IP November 1996
Management stations execute management applications which monitor and
control managed elements. Managed elements are devices such as
hosts, routers, terminal servers, etc., which are monitored and
controlled via access to their management information.
Management information is viewed as a collection of managed objects,
residing in a virtual information store, termed the Management
Information Base (MIB). Collections of related objects are defined
in MIB modules. These modules are written using a subset of OSI's
Abstract Syntax Notation One (ASN.1) [1], termed the Structure of
Management Information (SMI) [2].
This document is the MIB module which defines managed objects for
managing implementations of the Internet Protocol (IP) [3] and its
associated Internet Control Message Protocol (ICMP) [4].
The managed objects in this MIB module were originally defined using
the SNMPv1 framework as a part of MIB-II [5]. Since then, the
managed objects related to managing routes in an IP internet were
updated by RFC 1354 [6]. This document takes the remaining MIB-II
objects for these protocols, and defines them using the SNMPv2
framework.

DESCRIPTION
"The indication of whether this entity is acting as an IP
router in respect to the forwarding of datagrams received
by, but not addressed to, this entity. IP routers forward

SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"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 routers and therefore do not forward datagrams, this
counter includes datagrams discarded because the destination
address was not a local address."

SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"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 routers,
this counter will include only those packets which were
Source-Routed via this entity, and the Source-Route option
processing was successful."

transmission. Note that this counter does not include any
datagrams counted in ipForwDatagrams."

ipOutDiscards OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only

DESCRIPTION
"The type of mapping.
McCloghrie Standards Track [Page 10]
RFC 2011 SNMPv2 MIB for IP November 1996
Setting this object to the value invalid(2) has the effect
of invalidating the corresponding entry in the
ipNetToMediaTable. That is, it effectively disassociates
the interface identified with said entry from the mapping
identified with said entry. It is an implementation-
specific matter as to whether the agent removes an
invalidated entry from the table. Accordingly, management
stations must be prepared to receive tabular information
from agents that corresponds to entries not currently in
use. Proper interpretation of such entries requires
examination of the relevant ipNetToMediaType object."
