Abstract
The purpose of this document is to describe coexistence between
version 3 of the Internet-standard Network Management Framework,
(SNMPv3), version 2 of the Internet-standard Network Management
Framework (SNMPv2), and the original Internet-standard Network
Management Framework (SNMPv1). This document also describes how to
convert MIB modules from SMIv1 format to SMIv2 format. This document
obsoletes RFC 2576.
