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].
