RFC 1398:Definitions of Managed Objects for ...
RFC-Ref

1. The Network Management Framework

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

      STD 16/RFC 1155std16 [3] which defines the SMI, the mechanisms used for
      describing and naming objects for the purpose of management.  STD
      16/RFC 1212std16 [13] defines a more concise description mechanism,
      which is wholly consistent with the SMI.

      RFC 1156hist [4] which defines MIB-I, the core set of managed objects
      for the Internet suite of protocols.  STD 17/RFC 1213std17 [6] defines
      MIB-II, an evolution of MIB-I based on implementation experience
      and new operational requirements.

      STD 15/RFC 1157hist [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.
