Status of this Memo
This memo defines an experimental version of an ISO
Transport Management Information Base for use with network
management protocols in TCP/IP-based internets. This memo
does not specify a standard for the Internet community.
However, after experimentation, if sufficient consensus is
reached in the Internet community, then a subsequent
revision of this document may be placed in the Internet-
standard MIB. This draft document will be submitted to the
RFC editor as a protocol specification. Distribution of
this memo is unlimited.
This document is an Internet Draft. Internet Drafts are
working documents of the Internet Engineering Task Force
(IETF), its Areas, and its Working Groups. Note that other
groups may also distribute working documents as Internet
Drafts.

progress."

INTERNET-DRAFT TP MIB 18 June 1992
1. Abstract
This memo defines an experimental version of an ISO
Transport Management Information Base for use with network
management protocols.
2. Introduction
This document defines an ISO Transport Management
Information Base for use with the network management
protocols. The ISO Transport network management document
[10] was used as a basis for this document.
The ISO Transport network management document [10] is a
draft document out for comment. The comment period ended
May 22, 1991. Therefore, this INTERNET-DRAFT may change to
accomodate any changes reflected in the final version of the
ISO Transport network management document [10].
3. Objects
The objects described in this document use the format
described in "Concise MIB Definitions" [6]. This document
should be referenced to fully understand section 4.
Consistent with the IAB directive to produce simple,
workable systems in the short-term, the list of managed
objects defined here, has been derived by taking only those
elements which are considered essential. This document only
describes ISO Transport class 4 specific objects.
