本标准包含IEEE Std 802.3（也称为以太网）的管理信息库（MIB）模块规范。它包括以前由互联网工程任务组（IETF）编制和发布的管理信息版本2（SMIv2）MIB模块规范的结构，以及IEEE标准802.3中以前规定的管理对象（GDMO）MIB模块定义指南中提供的管理对象分支和叶分配，以及最近对IEEE标准802.3的修订所产生的扩展。SMIv2 MIB模块旨在与通常用于管理以太网的简单网络管理协议（SNMP）一起使用。

This standard contains the Management Information Base (MIB) module specifications for IEEE Std 802.3, also known as Ethernet. It includes the Structure of Management Information Version 2 (SMIv2) MIB module specifications formerly produced and published by the Internet Engineering Task Force (IETF), and the managed object branch and leaf assignments provided in the Guidelines for the Definition of Managed Objects (GDMO) MIB modules formerly specified within IEEE Std 802.3, as well as extensions resulting from recent amendments to IEEE Std 802.3. The SMIv2 MIB modules are intended for use with the Simple Network Management Protocol (SNMP), commonly used to manage Ethernet.
