Management Information Base for network management of TCP/IP-based internets
Alternative Format: Original Text Document
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].
