- Status of this Memo
-
- This document is an Internet Draft. Internet Drafts are
- working documents of the Internet Engineering Task Force
- (IETF), its Areas, and its Working Groups. Note that other
- groups may also distribute working documents as Internet
- Drafts.
-
- Internet Drafts are draft documents valid for a maximum of six
- months. Internet Drafts may be updated, replaced, or
- obsoleted by other documents at any time. It is not
- appropriate to use Internet Drafts as reference material or to
- cite them other than as a ``working draft'' or ``work in
- progress.'' Please check the 1id-abstracts.txt listing
- contained in the internet-drafts Shadow Directories on

-
-
- This document will be submitted to the Internet Activities
- Board as a Draft Standard. This document defines an
- experimental extension to the SNMP MIB. Upon publication as a
- Draft Standard, a new MIB number will be assigned. This is a
- working document only, it should neither be cited nor quoted
- in any formal document.
-
- This document will expire before 1 Feb. 1993.

- 1. Abstract
-
- This memo defines an experimental 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 bridge Network
- Control Protocol[10] on subnetwork interfaces using the family
- of Point-to-Point Protocols.
-
- This memo does not specify a standard for the Internet
- community.

- 2. The Network Management Framework
-
- The Internet-standard Network Management Framework consists of
- three components. They are:
-
- RFC 1155 which defines the SMI, the mechanisms used for
- describing and naming objects for the purpose of
- management. RFC 1212 defines a more concise description
- mechanism, which is wholly consistent with the SMI.
-
- RFC 1156 which defines MIB-I, the core set of managed
- objects for the Internet suite of protocols. RFC 1213,
- defines MIB-II, an evolution of MIB-I based on
- implementation experience and new operational
- requirements.
-
- 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.

- 3. 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 has a name, a syntax, and an encoding. The name is an
- object identifier, an administratively assigned name, which
- specifies an object type. 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 OBJECT DESCRIPTOR, to also
- refer to the object type.
-
- The syntax of an object type defines the abstract data
- structure corresponding to that object type. The ASN.1
- language is used for this purpose. However, the SMI [1]
- purposely restricts the ASN.1 constructs which may be used.
- These restrictions are explicitly made for simplicity.
-
- The encoding of an object type is simply how that object type
- is represented using the object type's syntax. Implicitly
- tied to the notion of an object type's syntax and encoding is
- how the object type is represented when being transmitted on
- the network.
-
- The SMI specifies the use of the basic encoding rules of ASN.1
- [4], subject to the additional requirements imposed by the
- SNMP.
-
-
- 3.1. Format of Definitions
-
- Section 5 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].

- 4. Overview
-
- 4.1. 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.
-
-
- 4.2. 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 understanding some of the basic design
- decisions of the MIB.
-
- The PPP is not one single protocol but a large family of
- protocols. Each of these is, in itself, a fairly complex
- protocol. The PPP protocols may be divided into three rough
- categories:
-
- Control Protocols
- The Control Protocols are used to control the operation
- of the PPP. The Control Protocols include the Link
- Control Protocol (LCP), the Password Authentication
- Protocol (PAP), the Link Quality Report (LQR), and the
- Challenge Handshake Authentication Protocol (CHAP).
-
- Network Protocols
- The Network Protocols are used to move the network
- traffic over the PPP interface. A Network Protocol
-
-
-
-
-
- Frank J. Kastenholz Exp. 1 Feb. 1993 [Page 5]
-
-
-
-
-
- Internet Draft PPP/Bridge MIB July 1992
-
-
- encapsulates the datagrams of a specific higher-layer
- protocol that is using the PPP as a data link. Note that
- within the context of PPP, the term "Network Protocol"
- does not imply an OSI Layer-3 protocol; for instance,
- there is a Bridging network protocol.
-
- Network Control Protocols (NCPs)
- The NCPs are used to control the operation of the Network
- Protocols. Generally, each Network Protocol has its own
- Network Control Protocol; thus, the IP Network Protocol
- has its IP Control Protocol, the Bridging Network
- Protocol has its Bridging Network Control Protocol and so
- on.
-
- This document specifies the objects used in managing one of
- these protocols, namely the Bridge Network Control Protocol.
-
-
- 4.3. MIB Groups
-
- Objects in this MIB are arranged into several MIB groups.
- Each group is organized as a set of related objects.
-
- These groups are the basic unit of conformance: if the
- semantics of a group is applicable to an implementation then
- all objects in the group must be implemented.
-
- The PPP MIB is organized into several MIB Groups, including,
- but not limited to, the following groups:
- o The PPP Link Group
- o The PPP LQR Group
- o The PPP LQR Extensions Group
- o The PPP IP Group
- o The PPP Bridge Group
- o The PPP Security Configuration Group
- o The PPP CHAP Group
- o The PPP PAP Group
-
- This document specifies the following group:
-
- The PPP Bridge Group
- The PPP Bridge Group contains configuration, status, and
- control variables that apply to the operation of Bridging
- over PPP.

- 7. Security Considerations
-
- The PPP MIB affords the network operator the ability to
- configure and control the PPP links of a particular system,
- including the PPP authentication protocols. This represents a
- security risk.
-
- These risks are addressed in the following manners:
-
- (1) All variables which represent a significant security risk
- are placed in separate, optional, MIB Groups. As the MIB
- Group is the quantum of implementation within a MIB, the
- implementor of the MIB may elect not to implement these
- groups.
-
- (2) The implementor may choose to implement the variables
- which present a security risk so that they may not be
- written, i.e., the variables are READ-ONLY. This method
- still presents a security risk, and is not recommended,
- in that the variables, specifically the PPP
- Authentication Protocols' variables, may be easily read.
-
- (3) Using the new SNMP administrative framework[13,14], the
- operator can place the variables into MIB views which are
- protected in that the parties which have access to those
- MIB views use authentication and privacy protocols, or
- the operator may elect to make these views not accessible
- to any party. In order to facilitate this placement, all
- security-related variables are placed in separate MIB
- Tables. This eases the identification of the necessary
- MIB View Subtree.
