The Definitions of Managed Objects for
the IP Network Control Protocol of
the Point-to-Point Protocol
Status of this Memo
This RFC specifies an IAB standards track protocol for the Internet
community, and requests discussion and suggestions for improvements.
Please refer to the current edition of the "IAB Official Protocol
Standards" for the standardization state and status of this protocol.
Distribution of this memo is unlimited.
Abstract
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in TCP/IP-based internets.
In particular, it describes managed objects used for managing the IP
Network Control Protocol on subnetwork interfaces using the family of
Point-to-Point Protocols [8, 9, 10, 11, & 12].

1. The Network Management Framework
The Internet-standard Network Management Framework consists of three
components. They are:
STD 16/RFC 1155 which defines the SMI, the mechanisms used for
describing and naming objects for the purpose of management. STD
16/RFC 1212 defines a more concise description mechanism, which is

wholly consistent with the SMI.
STD 17/RFC 1213 which defines MIB-II, the core set of managed
objects for the Internet suite of protocols.
STD 15/RFC 1157 which defines the SNMP, the protocol used for
network access to managed objects.
The Framework permits new objects to be defined for the purpose of
experimentation and evaluation.
2. Objects
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the subset of Abstract Syntax Notation One (ASN.1) [3]
defined in the SMI. In particular, each object type is named by an
OBJECT IDENTIFIER, an administratively assigned name. The object
type together with an object instance serves to uniquely identify a
specific instantiation of the object. For human convenience, we
often use a textual string, termed the descriptor, to refer to the
object type.
2.1. Format of Definitions
Section 4 contains the specification of all object types contained in
this MIB module. The object types are defined using the conventions
defined in the SMI, as amended by the extensions specified in [5,6].
3. Overview
3.1. Object Selection Criteria
To be consistent with IAB directives and good engineering practice,
an explicit attempt was made to keep this MIB as simple as possible.
This was accomplished by applying the following criteria to objects
proposed for inclusion:
(1) Require objects be essential for either fault or
configuration management. In particular, objects for
which the sole purpose was to debug implementations were
explicitly excluded from the MIB.
(2) Consider evidence of current use and/or utility.
(3) Limit the total number of objects.
(4) Exclude objects which are simply derivable from others in

this or other MIBs.
3.2. Structure of the PPP
This section describes the basic model of PPP used in developing the
PPP MIB. This information should be useful to the implementor in
