Description

English:
Device and link notification subtree. Covers link down, link flapping, device offline and neighbour change events, and is the notification counterpart of the device object (1.3.6.1.4.1.59719.4.1) and the interface object (1.3.6.1.4.1.59719.4.2).
Numbering convention: 1 to 9 for fault notifications, 10 to 19 for recovery notifications, 20 to 99 reserved for future extension. Every fault notification shall have a paired recovery notification so that the management station can close an alarm automatically.
Status: registered but unused. No device and link notification identifier has been emitted by any device or platform. Before first use, define the flapping detection window and the suppression rule, because link flapping is the most frequent source of alarm storms. The unused state shall be re-verified at each revision of this file.
Recommendation: Identify the device by its unique identity (1.3.6.1.4.1.59719.1.100) and the interface by its interface object, and never by a display name that may change after a configuration edit.
See also: 1.3.6.1.4.1.59719.0.5.1 to 1.3.6.1.4.1.59719.0.5.10, 1.3.6.1.4.1.59719.4.1, 1.3.6.1.4.1.59719.4.2.
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:
设备与链路通知子树。覆盖链路中断、链路抖动、设备离线与邻居变更类事件，是设备对象（1.3.6.1.4.1.59719.4.1）与接口对象（1.3.6.1.4.1.59719.4.2）在通知维度的对应弧。
编号规则：1-9 为故障类通知，10-19 为恢复类通知，20-99 预留未来扩展。每条故障通知都应配有成对的恢复通知，以便网管侧自动闭环告警。
状态：已注册但未使用。尚无设备或平台上报过任何设备与链路通知标识。首次使用前应定义抖动检测窗口与抑制规则，因为链路抖动是告警风暴最主要的来源。本文件每次修订时须重新核验该未使用状态。
建议：设备应以唯一身份（1.3.6.1.4.1.59719.1.100）标识、接口应以接口对象标识，不得使用配置变更后可能改变的显示名。
关联节点：1.3.6.1.4.1.59719.0.5.1 至 1.3.6.1.4.1.59719.0.5.10、1.3.6.1.4.1.59719.4.1、1.3.6.1.4.1.59719.4.2。
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。
