  41. 1.  Status of this Memo
  42.  
  43.    This memo provides the initial version of the Management Information
  44.    Base (MIB) for use with network management protocols in TCP/IP-based
  45.    internets in the short-term.  In particular, together with its
  46.    companion memos which describe the structure of management
  47.    information along with the initial network management protocol, these
  48.    documents provide a simple, workable architecture and system for
  49.    managing TCP/IP-based internets and in particular the Internet.

  63.    This memo specifies a draft standard for the Internet community.
  64.    TCP/IP implementations in the Internet which are network manageable
  65.    are expected to adopt and implement this specification.

  69. 2.  IAB POLICY STATEMENT
  70.  
  71.    This MIB specification is the first edition of an evolving document
  72.    defining variables needed for monitoring and control of various
  73.    components of the Internet.  Not all groups of defined variables are
  74.    mandatory for all Internet components.
  75.  
  76.    For example, the EGP group is mandatory for gateways using EGP but
  77.    not for hosts which should not be running EGP.  Similarly, the TCP
  78.    group is mandatory for hosts running TCP but not for gateways which
  79.    aren't running it.  What IS mandatory, however, is that all variables
  80.    of a group be supported if any element of the group is supported.
  81.  
  82.    It is expected that additional MIB groups and variables will be
  83.    defined over time to accommodate the monitoring and control needs of
  84.    new or changing components of the Internet.  The MIB working group
  85.    will continue to refine this specification and projects a revision
  86.    incorporating new requirements in early 1989.
  87.  
  88. 3.  Introduction
  89.  
  90.    As reported in RFC 1052, IAB Recommendations for the Development of
  91.    Internet Network Management Standards [1], the Internet Activities
  92.    Board has directed the Internet Engineering Task Force (IETF) to
  93.    create two new working groups in the area of network management.  One
  94.    group is charged with the further specification and definition of
  95.    elements to be included in the Management Information Base.  The
  96.    other is charged with defining the modifications to the Simple
  97.    Network Management Protocol (SNMP) to accommodate the short-term
  98.    needs of the network vendor and operator communities.  The long-term
  99.    needs of the Internet community are to be met using the ISO CMIS/CMIP
  100.    [2,3] framework as a basis.  An existing IETF working group, the
  101.    "NETMAN" group, is already engaged in defining the use of CMIS/CMIP
  102.    in a TCP/IP network, and will continue with responsibility for
  103.    addressing the longer-term requirements.
  104.  
  105.    The output of the MIB working group is to be provided to both  the
  106.    SNMP working  group  and  the  NETMAN group, so as to ensure
  107.    compatibility of monitored items for both network management
  108.    frameworks.
  109.  
  110.    The MIB working group has produced this memo and a companion.  The
  111.  
  112.  
  113.  
  114. McCloghrie & Rose                                               [Page 2]
  115.  
  116. RFC 1066                          MIB                        August 1988
  117.  
  118.  
  119.    companion memo [4] defines a Structure for Management Information
  120.    (SMI) for use by the managed objects contained in the MIB.  This memo
  121.    defines the list of managed objects.
  122.  
  123.    The IAB also urged the working groups to be "extremely sensitive to
  124.    the need to keep SNMP simple," and recommends that the MIB working
  125.    group take as its starting inputs the MIB definitions found in the
  126.    High-Level Entity Management Systems (HEMS) RFC 1024 [5], the initial
  127.    SNMP specification [6], and the CMIS/CMIP memos [7,8].
  128.  
  129.    Thus, the list of managed objects defined here, has been derived by
  130.    taking only those elements which are considered essential.  Since
  131.    such elements are essential, there is no need to allow the
  132.    implementation of individual objects, to be optional.  Rather, all
  133.    compliant implementations will contain all applicable (see below)
  134.    objects defined in this memo.
  135.  
  136.    This approach of taking only the essential objects is NOT
  137.    restrictive, since the SMI defined in the companion memo provides
  138.    three extensibility mechanisms: one, the addition of new standard
  139.    objects through the definitions of new versions of the MIB; two, the
  140.    addition of widely-available but non-standard objects through the
  141.    multilateral subtree; and three, the addition of private objects
  142.    through the enterprises subtree. Such additional objects can not only
  143.    be used for vendor-specific elements, but also for experimentation as
  144.    required to further the knowledge of which other objects are
  145.    essential.
  146.  
  147.    The primary criterion for being considered essential was for an
  148.    object to be contained in all of the above referenced MIB
  149.    definitions.  A few other objects have been included, but only if the
  150.    MIB working group believed they are truly essential.  The detailed
  151.    list of criteria against which potential inclusions in this (initial)
  152.    MIB were considered, was:
  153.  
  154.       1) An object needed to be essential for either fault or
  155.          configuration management.
  156.  
  157.       2) Only weak control objects were permitted (by weak, it
  158.          is meant that tampering with them can do only limited
  159.          damage).  This criterion reflects the fact that the
  160.          current management protocols are not sufficiently secure
  161.          to do more powerful control operations.
  162.  
  163.       3) Evidence of current use and utility was required.
  164.  
  165.       4) An attempt was made to limit the number of objects to
  166.          about 100 to make it easier for vendors to fully
  167.

  175.          instrument their software.
  176.  
  177.       5) To avoid redundant variables, it was required that no
  178.          object be included that can be derived from others in the
  179.          MIB.
  180.  
  181.       6) Implementation specific objects (e.g., for BSD UNIX)
  182.          were excluded.
  183.  
  184.       7) It was agreed to avoid heavily instrumenting critical
  185.          sections of code.  The general guideline was one counter
  186.          per critical section per layer.

  231. 4.  Objects
  232.  
  233.    Managed objects are accessed via a virtual information store, termed
  234.    the Management Information Base or MIB.  Objects in the MIB are
  235.    defined using Abstract Syntax Notation One (ASN.1) [9].
  236.  
  237.    The mechanisms used for describing these objects are specified in the
  238.    companion memo.  In particular, each object has a name, a syntax, and
  239.    an encoding.  The name is an object identifier, an administratively
  240.    assigned name, which specifies an object type.  The object type
  241.    together with an object instance serves to uniquely identify a
  242.    specific instantiation of the object.  For human convenience, we
  243.    often use a textual string, termed the OBJECT DESCRIPTOR, to also
  244.    refer to the object type.
  245.  
  246.    The syntax of an object type defines the abstract data structure
  247.    corresponding to that object type.  The ASN.1 language is used for
  248.    this purpose.  However, the companion memo purposely restricts the
  249.    ASN.1 constructs which may be used.  These restrictions are
  250.    explicitly made for simplicity.
  251.  
  252.    The encoding of an object type is simply how that object type is
  253.    represented using the object type's syntax.  Implicitly tied to the
  254.    notion of an object type's syntax and encoding is how the object type
  255.    is represented when being transmitted on the network.  This memo
  256.    specifies the use of the basic encoding rules of ASN.1 [10].
  257.  
  258. 4.1.  Object Groups
  259.  
  260.    Since this list of managed objects contains only the essential
  261.    elements, there is no need to allow individual objects to be
  262.    optional.  Rather, the objects are arranged into the following
  263.    groups:
  264.  
  265.                   - System
  266.                   - Interfaces
  267.                   - Address Translation
  268.                   - IP
  269.                   - ICMP
  270.                   - TCP
  271.                   - UDP
  272.                   - EGP
  273.  
  274.    There are two reasons for defining these groups: one, to provide a
  275.    means of assigning object identifiers; two, to provide a method for
  276.    implementations of managed agents to know which objects they must
  277.    implement.  This method is as follows: if the semantics of a group is
  278.    applicable to an implementation, then it must implement all objects
  279.  
  280.  
  281.

  283.  
  284. RFC 1066                          MIB                        August 1988
  285.  
  286.  
  287.    in that group.  For example, an implementation must implement the EGP
  288.    group if and only if it implements the EGP protocol.
  289.  
  290. 4.2.  Format of Definitions
  291.  
  292.    The next section contains the specification of all object types
  293.    contained in the MIB. Following the conventions of the companion
  294.    memo, the object types are defined using the following fields:
  295.  
  296.           OBJECT:
  297.           -------
  298.                A textual name, termed the OBJECT DESCRIPTOR, for the
  299.                object type, along with its corresponding OBJECT
  300.                IDENTIFIER.
  301.  
  302.           Syntax:
  303.                The abstract syntax for the object type, presented using
  304.                ASN.1.  This must resolve to an instance of the ASN.1
  305.                type ObjectSyntax defined in the SMI.
  306.  
  307.           Definition:
  308.                A textual description of the semantics of the object
  309.                type.  Implementations should ensure that their
  310.                interpretation of the object type fulfills this
  311.                definition since this MIB is intended for use in multi-
  312.                vendor environments.  As such it is vital that object
  313.                types have consistent meaning across all machines.
  314.  
  315.           Access:
  316.                One of read-only, read-write, write-only, or
  317.                not-accessible.
  318.  
  319.           Status:
