Definitions of Managed Objects for the Ethernet-like Interface Types

RFC 1643                   Ethernet-Like MIB                   July 1994


1.  The SNMP Network Management Framework

   The SNMP Network Management Framework consists of three major
   components.  They are:

      o    STD 16/RFC 1155 [3] which defines the SMI, the mechanisms
           used for describing and naming objects for the purpose of
           management.  STD 16/RFC 1212 [13] defines a more concise
           description mechanism, which is wholly consistent with
           the SMI.

      o    RFC 1156 [4] which defines MIB-I, the core set of managed
           objects for the Internet suite of protocols.  STD 17/RFC
           1213 [6] defines MIB-II, an evolution of MIB-I based on
           implementation experience and new operational
           requirements.

      o    STD 15/RFC 1157 [5] 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) [7]
   defined in the SMI [16].  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.  Change Log

   This section enumerates changes made to RFC 1398 to produce this
   document.

    (1)   A section describing the applicability of various parts
          of RFC 1573 to ethernet-like interfaces has been added.

    (2)   A minor error in the description of the TDR test was
          fixed.

    (3)   A loopback test was defined to replace the standard
          loopback test that was defined in RFC 1229.
