1.  Abstract

   This memo defines the second version of the Management Information
   Base (MIB-II) for use with network management protocols in TCP/IP-
   based internets.  In particular, together with its companion memos
   which describe the structure of management information (RFC 1155)
   along with the network management protocol (RFC 1157) for TCP/IP-
   based internets, these documents provide a simple, workable
   architecture and system for managing TCP/IP-based internets and in
   particular the Internet community.

2.  Introduction

   As reported in RFC 1052, IAB Recommendations for the Development of
   Internet Network Management Standards [1], a two-prong strategy for
   network management of TCP/IP-based internets was undertaken.  In the
   short-term, the Simple Network Management Protocol (SNMP) was to be
   used to manage nodes in the Internet community.  In the long-term,
   the use of the OSI network management framework was to be examined.
   Two documents were produced to define the management information: RFC
   1065, which defined the Structure of Management Information (SMI)
   [2], and RFC 1066, which defined the Management Information Base
   (MIB) [3].  Both of these documents were designed so as to be
