Definition of Managed Objects for IEEE 802

RFC 1368                   802.3 Repeater MIB               October 1992


   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 [6],
   subject to the additional requirements imposed by the SNMP.

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 [7,8].

3.  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 [9].

   These Repeater MIB objects may be used to manage non-standard
   repeater-like devices, but defining objects to describe
   implementation-specific properties of non-standard repeater-like
   devices is outside the scope of this memo.

   The definitions presented here are based on the IEEE draft standard
   P802.3K, "Layer Management for 10 Mb/s Baseband Repeaters." [10]
   Implementors of these MIB objects should note that [10] explicitly
   describes 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 802.3 Repeater Management draft, with the
   intention that a single instrumentation can be used to implement both
   the IEEE and IETF management standards.

3.1.  Terminology

3.1.1.  Repeaters, Hubs and Concentrators

   In late 1988, the IEEE 802.3 Hub Management task force was chartered
   to define managed objects for both 802.3 repeaters and the proposed
   10BASE-FA synchronous active stars.  The term "hub" was used to cover
   both repeaters and active stars.

   In March, 1991, the active star proposal was dropped from the
   10BASE-F draft.  Subsequently the 802.3 group changed the name of the
