                     Definitions of Managed Objects
                    for IEEE 802.3 Repeater Devices

Status of this Memo

   This RFC 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" 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 the Internet community.
   In particular, it defines objects for managing IEEE 802.3 10
   Mb/second baseband repeaters, sometimes referred to as "hubs."

1.  The Network Management Framework

   The Internet-standard Network Management Framework consists of
    three components.  They are:

      o 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.

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

      o 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.

1.1.  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.

2.  Overview

   Instances of the object types defined in this memo represent
   attributes of an IEEE 802.3 (Ethernet-like) repeater, as defined by
   Section 9, "Repeater Unit for 10 Mb/s Baseband Networks" in the IEEE
   802.3/ISO 8802-3 CSMA/CD standard [7].
