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 describes managed objects used for managing Network
Interfaces.
This memo discusses the 'interfaces' group of MIB-II, especially the
experience gained from the definition of numerous media-specific MIB
modules for use in conjunction with the 'interfaces' group for
managing various sub-layers beneath the internetwork-layer. It
proposes clarifications to, and extensions of, the architectural
issues within the current model used for the 'interfaces' group.
This memo also includes a MIB module. As well as including new MIB
definitions to support the architectural extensions, this MIB module
also re-specifies the 'interfaces' group of MIB-II in a manner which
is both compliant to the SNMPv2 SMI and semantically-identical to the
existing SNMPv1-based definitions.
2. The SNMPv2 Network Management Framework
The SNMPv2 Network Management Framework consists of four major
components. They are:
o RFC 1442 which defines the SMI, the mechanisms used for
describing and naming objects for the purpose of management.
