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 defines objects for
   managing 100Mb/second repeaters based on IEEE 802.12.

   This memo does not specify a standard for the Internet community.


2.  The SNMPv2 Network Management Framework

   The SNMPv2 Network Management Framework consists of four major
   components.  They are:

      o    RFC 1442 which defines the SMI, the mechanisms used for
           describing and naming objects for the purpose of management.

      o    STD 17, RFC 1213 defines MIB-II, the core set of managed
           objects for the Internet suite of protocols.

      o    RFC 1445 which defines the administrative and other
           architectural aspects of the framework.

      o    RFC 1448 which defines the protocol used for network access
           to managed objects.

   The Framework permits new objects to be defined for the purpose of
   experimentation and evaluation.


2.1.  Object Definitions

   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)
   defined in the SMI.  In particular, each object 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.


3.  Overview

   Instances of these object types represent attributes of an IEEE
   802.12 (100VG-AnyLAN) repeater, as defined by Section 12, "RMAC

   Protocol" in the IEEE 802.12 Demand Priority Access Method Standard
   [6].

   The definitions presented here are based on Section 13, "Layer
   Management Functions and Services", and Annex E, "GDMO Specifications
   for Demand Priority Managed Objects" of IEEE Standard 802.12 [6].
   Implementors of these MIB objects should note that [6] explicitly
   describes (in the form of Pascal pseudocode) when, where, and how
   various repeater attributes are measured.  The IEEE document also
   describes the effects of repeater actions that may be invoked by
   manipulating instances of the MIB objects defined here.

   The counters in this document are defined to be the same as those
   counters in the IEEE 802.12 Standard, with the intention that the
   same instrumentation can be used to implement both the IEEE and IETF
   management standards.

              DESCRIPTION
                      "Setting this object to reset(2) causes the
                      repeater to transition to its initial state as
                      specified in clause 12 [IEEE Std 802.12].

                      Setting this object to noReset(1) has no effect.
                      The agent will always return the value noReset(1)
                      when this object is read.

                      After receiving a request to set this variable to
                      reset(2), the agent is allowed to delay the reset
                      for a short period.  For example, the implementor
                      may choose to delay the reset long enough to
                      allow the SNMP response to be transmitted.  In
                      any event, the SNMP response must be transmitted.

                      This action does not reset the management
                      counters defined in this document nor does it
                      affect the vgRptrPortAdminStatus parameters.
                      Included in this action is the execution of a
                      disruptive Self-Test with the following
                      characteristics:

                          1) The nature of the tests is not specified.
                          2) The test resets the repeater but without
                            affecting configurable management
                            information about the repeater.
                          3) Packets received during the test may or
                             may not be transferred.
                          4) The test does not interfere with
                             management functions.

                      After performing this self-test, the agent will

                          2) The test does not change the state of the
                             repeater or management information about
                             the repeater.
                          3) The test does not inject packets onto any

                      Note that this definition allows returning an

                      The agent must reject a SET of this object if the

                      supported by this port's hardware, as defined by
                      the values of the corresponding instances of
                      vgRptrPortSupportedPromiscMode and
                      vgRptrPortSupportedCascadeMode.

                      Note that vgRptrPortSupportPromiscMode and
                      vgRptrPortSupportedCascadeMode represent what the
                      port hardware is capable of supporting.
                      vgRptrPortAllowedTrainType is used for setting an
                      administrative policy for a port.  The actual set
                      of training configurations that will be allowed
                      to succeed on a port is the intersection of what
                      the hardware will support and what is
                      administratively allowed.  The above requirement
                      on what values may be set to this object says that
                      the intersection of what is supported and what is
                      allowed must be non-empty.  In other words, it
                      must not result in a situation in which nothing
                      would be allowed to train on that port.  However,
                      a value can be set to this object as long as the
                      combination of this object and what is supported
                      by the hardware would still leave at least one
                      configuration that could successfully train on the
                      port."
