RFC 1748 IEEE 802.5 MIB using SMIv2 December 1994
2. The SNMPv2 Network Management Framework
The SNMPv2 Network Management Framework consists of four major
components. They are:
o RFC 1442 [1] which defines the SMI, the mechanisms used for
describing and naming objects for the purpose of management.
o STD 17, RFC 1213 [2] defines MIB-II, the core set of managed
objects for the Internet suite of protocols.
o RFC 1445 [3] which defines the administrative and other
architectural aspects of the framework.
o RFC 1448 [4] 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. 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.
3. Overview
This memo defines three tables: the 802.5 Interface Table, which
contains state and parameter information which is specific to 802.5
interfaces, the 802.5 Statistics Table, which contains 802.5
interface statistics, and the 802.5 Timer Table, which contains the
values of 802.5-defined timers. A managed system will have one entry
in the 802.5 Interface Table and one entry in the 802.5 Statistics
Table for each of its 802.5 interfaces. The 802.5 Timer Table is
obsolete, but its definition has been retained in this memo for
backward compatibility.
This memo also defines OBJECT IDENTIFIERs, some to identify interface
tests for use with the ifTestTable [6], and some to identify Token
Ring interface Chip Sets.
