ISO/IEC/IEEE 8802-1AB:2017的范围是定义协议和管理元素，适用于向连接到同一IEEE 802 LAN的站点发布信息，以填充物理拓扑和设备发现管理信息数据库。该协议有助于识别由IEEE 802 LAN/MAN连接的站点、它们的互连点和管理协议的接入点。 ISO/IEC/IEEE 8802-1AB:2017定义了一个协议 a） 向同一IEEE 802 LAN上的相邻站点播发有关本地站点的连接和管理信息。 b） 从同一IEEE 802 LAN上的相邻站点接收网络管理信息。 c） 可与所有IEEE 802接入协议和网络介质一起运行。 d） 建立网络管理信息架构和对象定义，这些架构和对象定义适用于存储有关相邻站点的连接信息。 e） 提供与IETF PTOPO MIB（IETF RFC 2922[B9]）的兼容性。1

The scope of ISO/IEC/IEEE 8802-1AB:2017 is to define a protocol and management elements, suitable for advertising information to stations attached to the same IEEE 802 LAN, for the purpose of populating physical topology and device discovery management information databases. The protocol facilitates the identification of stations connected by IEEE 802 LANs/MANs, their points of interconnection, and access points for management protocols. ISO/IEC/IEEE 8802-1AB:2017 defines a protocol that a) Advertises connectivity and management information about the local station to adjacent stations on the same IEEE 802 LAN. b) Receives network management information from adjacent stations on the same IEEE 802 LAN. c) Operates with all IEEE 802 access protocols and network media. d) Establishes a network management information schema and object definitions that are suitable for storing connection information about adjacent stations. e) Provides compatibility with the IETF PTOPO MIB (IETF RFC 2922 [B9]).1
