Definitions of Managed Objects for the Ethernet-like Interface Types
Alternative Format: Original Text Document
RFC 1643 Ethernet-Like MIB July 1994
1. The SNMP Network Management Framework
The SNMP Network Management Framework consists of three major
components. They are:
o STD 16/RFC 1155 [3] which defines the SMI, the mechanisms
used for describing and naming objects for the purpose of
management. STD 16/RFC 1212 [13] defines a more concise
description mechanism, which is wholly consistent with
the SMI.
o RFC 1156 [4] which defines MIB-I, the core set of managed
objects for the Internet suite of protocols. STD 17/RFC
1213 [6] defines MIB-II, an evolution of MIB-I based on
implementation experience and new operational
requirements.
o STD 15/RFC 1157 [5] which defines the SNMP, the protocol
used for network access to managed objects.
The Framework permits new objects to be defined for the purpose of
experimentation and evaluation.
1.1. 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) [7]
defined in the SMI [16]. In particular, each object 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.
2. Change Log
This section enumerates changes made to RFC 1398 to produce this
document.
(1) A section describing the applicability of various parts
of RFC 1573 to ethernet-like interfaces has been added.
(2) A minor error in the description of the TDR test was
fixed.
(3) A loopback test was defined to replace the standard
loopback test that was defined in RFC 1229.
