RFC 1156 (rfc1156) - Page 2 of 91
Management Information Base for network management of TCP/IP-based internets
Alternative Format: Original Text Document
RFC 1156 MIB May 1990
information along with the initial 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.
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. IAB Policy Statement
This MIB specification is the first edition of an evolving document
defining variables needed for monitoring and control of various
components of the Internet. Not all groups of defined variables are
mandatory for all Internet components.
For example, the EGP group is mandatory for gateways using EGP but
not for hosts which should not be running EGP. Similarly, the TCP
group is mandatory for hosts running TCP but not for gateways which
aren't running it. What IS mandatory, however, is that all variables
of a group be supported if any element of the group is supported.
It is expected that additional MIB groups and variables will be
defined over time to accommodate the monitoring and control needs of
new or changing components of the Internet. The responsible working
group(s) will continue to refine this specification.
3. Introduction
As reported in RFC 1052, IAB Recommendations for the Development of
Internet Network Management Standards [1], the Internet Activities
Board has directed the Internet Engineering Task Force (IETF) to
create two new working groups in the area of network management. One
group was charged with the further specification and definition of
