本建议|国际标准提供了开放式环境中管理信息的规范 与本建议规范中规定的OSI物理层操作相关的系统| 国际标准。关于如何实现物理层管理的细节超出了本文的范围 建议|国际标准。物理层管理通过指定以下内容来定义: ? 物理层托管对象的托管对象类定义遵循 管理信息的结构（参见ITU-T Rec.X.720 | ISO/IEC 10165-1至X.723| ISO/IEC 10165-5； ? 受管对象和属性与图层操作和其他对象的关系 层的对象和属性；和 ? 对OSI可用的物理层管理对象属性的操作类型 系统管理。

This Recommendation | International Standard provides the specification of management information within an Open System related to those operations of the OSI Physical Layer specified by the specifications in this Recommendation | International Standard. Specifics on how Physical Layer management is accomplished is beyond the scope of this Recommendation | International Standard. Physical Layer management is defined by specifying: ? the managed object class definition of Physical Layer Managed Objects following guidelines put forth by the Structure of Management Information (see ITU-T Recs. X.720 | ISO/IEC 10165-1 to X.723 | ISO/IEC 10165-5; ? the relationship of the Managed Objects and attributes to both the operation of the layer and to other objects and attributes of the layer; and ? the action type operations on the attributes of Physical Layer Managed Objects that are available to OSI Systems Management.
