Definitions of Managed Objects for SNA NAUs using SMIv2
Alternative Format: Original Text Document
RFC 1666 SNANAU MIB August 1994
1. Introduction
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it defines objects for managing the configuration,
monitoring and control of Physical Units (PUs) and Logical Units
(LUs) in an SNA environment. PUs and LUs are two types of Network
Addressable Units (NAUs) in the logical structure of an SNA network.
NAUs are the origination or destination points for SNA data streams.
This memo identifies managed objects for PU Type 1.0, 2.0 and Type
2.1 and LU Type 0, 1, 2, 3, 4, 7. The generic objects defined here
can also be used to manage LU 6.2 and any LU-LU session. The SNA
terms and overall architecture are documented in [1].
2. The SNMPv2 Network Management Framework
The SNMPv2 Network Management Framework consists of four major
components. They are:
o RFC 1442 [2] which defines the SMI, the mechanisms used for
describing and naming objects for the purpose of management.
o STD 17, RFC 1213 [3] defines MIB-II, the core set of
managed objects for the Internet suite of protocols.
o RFC 1445 [4] which defines the administrative and other
architectural aspects of the framework.
o RFC 1448 [5] which defines the protocol used for network
access to managed objects.
The Framework permits new objects to be defined for the purpose of
experimentation and evaluation.
2.1. Object Definitions
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the subset of Abstract Syntax Notation One (ASN.1)
defined in the SMI (RFC 1442 [2]). In particular, each object type
is named by an OBJECT IDENTIFIER, an administratively assigned name.
The object type together with an object instance serves to uniquely
identify a specific instantiation of the object. For human
convenience, we often use a textual string, termed the descriptor, to
refer to the object type.
