Management Information Base for network management of TCP/IP-based internets

RFC 1156                          MIB                           May 1990


   elements to be included in the Management Information Base.  The
   other was charged with defining the modifications to the Simple
   Network Management Protocol (SNMP) to accommodate the short-term
   needs of the network vendor and operator communities.  In the long-
   term, the use of the OSI network management framework was to be
   examined using the ISO CMIS/CMIP [2,3] framework as a basis.  Two
   documents were produced to define the management information:  RFC
   1065, which defined the Structure of Management Information (SMI)
   [4], and RFC 1066, which defined the Management Information Base
   (MIB) [5].  Both of these documents were designed so as to be
   compatible with both the SNMP and the OSI network management
   framework.

   This strategy was quite successful in the short-term: Internet-based
   network management technology was fielded, by both the research and
   commercial communities, within a few months.  As a result of this,
   portions of the Internet community became network manageable in a
   timely fashion.

   As reported in RFC 1109, Report of the Second Ad Hoc Network
   Management Review Group [6], the requirements of the SNMP and the OSI
   network management frameworks were more different than anticipated.
   As such, the requirement for compatibility between the SMI/MIB and
   both frameworks was suspended.

   The IAB has designated the SNMP, SMI, and the initial Internet MIB to
   be full "Standard Protocols" with "Recommended" status.  By this
   action, the IAB recommends that all IP and TCP implementations be
   network manageable and that the implementations that are network
   manageable are expected to adopt and implement the SMI, MIB, and
   SNMP.

   As such, the current network management framework for TCP/IP- based
   internets consists of:  Structure and Identification of Management
   Information for TCP/IP-based Internets, which describes how managed
   objects contained in the MIB are defined as set forth in RFC 1155
   [7]; Management Information Base for Network Management of TCP/IP-
   based Internets, which describes the managed objects contained in the
   MIB as set forth in this memo; and, the Simple Network Management
   Protocol, which defines the protocol used to manage these objects, as
   set forth in RFC 1157 [8].

   The IAB also urged the working groups to be "extremely sensitive to
   the need to keep SNMP simple," and recommends that the MIB working
   group take as its starting inputs the MIB definitions found in the
   High-Level Entity Management Systems (HEMS) RFC 1024 [9], the initial
   SNMP specification [10], and the CMIS/CMIP memos [11,12].
