Description

English:
Unique identity object of the device, including the device serial number, hardware model, manufacturer information and hardware revision. It is used for asset identification, lifecycle management, license binding and certificate subject association.
Recommended encoding: the serial number shall use a stable, immutable, globally unique format, and the manufacturer shall be identified by the enterprise OID or a registered private enterprise number rather than free text.
Status: registered but unused. Not yet referenced by any MIB module, telemetry model or certificate profile; when used as a certificate subject attribute, register the attribute type under 1.3.6.1.4.1.59719.5.4. The unused state shall be re-verified at each revision of this file.
Recommendation: make this object the primary key for correlating the device certificate (1.3.6.1.4.1.59719.5.300), the asset record and the notifications emitted under 1.3.6.1.4.1.59719.0.1.
See also: 1.3.6.1.4.1.59719.5.4, 1.3.6.1.4.1.59719.4.1, 1.3.6.1.4.1.59719.0.1.1.
Verification: 2026-10-22 — this arc and all its sub-ordinates are confirmed unused; re-verify the unused state at each revision of this file.

中文:
设备唯一身份对象，包含设备序列号、硬件型号、厂商信息与硬件版本，用于资产识别、生命周期管理、许可证绑定与证书主体关联。
建议编码：序列号应采用稳定、不可变、全局唯一的格式；厂商应使用企业 OID 或已注册的私有企业编号标识，而非自由文本。
状态：已注册但未使用。尚未被任何 MIB 模块、遥测模型或证书模板引用；作为证书主体属性使用时，应在 1.3.6.1.4.1.59719.5.4 下登记属性类型。本文件每次修订时须重新核验该未使用状态。
建议：将本对象作为关联设备证书（1.3.6.1.4.1.59719.5.300）、资产台账与 1.3.6.1.4.1.59719.0.1 下各类通知的主键。
关联节点：1.3.6.1.4.1.59719.5.4、1.3.6.1.4.1.59719.4.1、1.3.6.1.4.1.59719.0.1.1。
核验：2026-10-22 —— 本弧及其全部下级标识均确认未使用，本文件每次修订时须重新核验该未使用状态。
