1.  Status of this Memo

   This RFC is a re-release of RFC 1065, with a changed "Status of this
   Memo", plus a few minor typographical corrections.  The technical

Rose & McCloghrie                                               [Page 1]
RFC 1155                          SMI                           May 1990

   content of the document is unchanged from RFC 1065.

   This memo provides the common definitions for the structure and
   identification of management information for TCP/IP-based internets.
   In particular, together with its companion memos which describe the
   management information base along with the network management
   protocol, these documents provide a simple, workable architecture and
   system for managing TCP/IP-based internets and in particular, the
   Internet.

   This memo specifies a Standard Protocol for the Internet community.
   Its status is "Recommended".  TCP/IP implementations in the Internet
   which are network manageable are expected to adopt and implement this
   specification.

   The Internet Activities Board recommends that all IP and TCP
   implementations be network manageable.  This implies implementation
   of the Internet MIB (RFC-1156) and at least one of the two
   recommended management protocols SNMP (RFC-1157) or CMOT (RFC-1095).
   It should be noted that, at this time, SNMP is a full Internet
   standard and CMOT is a draft standard.  See also the Host and Gateway
   Requirements RFCs for more specific information on the applicability
   of this standard.

   Please refer to the latest edition of the "IAB Official Protocol
   Standards" RFC for current information on the state and status of
   standard Internet protocols.

   Distribution of this memo is unlimited.

2.  Introduction

   This memo describes the common structures and identification scheme
   for the definition of management information used in managing
   TCP/IP-based internets.  Included are descriptions of an object
   information model for network management along with a set of generic
   types used to describe management information.  Formal descriptions
   of the structure are given using Abstract Syntax Notation One (ASN.1)
