1. Status of this Memo
This RFC is a re-release of RFC 1098, with a changed "Status of this
Memo" section plus a few minor typographical corrections. This memo
defines a simple protocol by which management information for a
network element may be inspected or altered by logically remote
users. In particular, together with its companion memos which
describe the structure of management information along with the
management information base, these documents provide a simple,
workable architecture and system for managing TCP/IP-based internets
and in particular the Internet.
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
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
