Description

English:
Link down notification. Reported when an interface or a link enters the down state.
Status: registered but unused. No device has emitted this notification. Before first use, define the debounce delay that distinguishes a real failure from a transient physical layer flap. The unused state shall be re-verified at each revision of this file.
Recommendation: Carry the interface object, the previous state, the current state and the down reason if available, and correlate the event with 1.3.6.1.4.1.59719.0.5.10 so that a short flap does not leave an open alarm.
See also: 1.3.6.1.4.1.59719.0.5, 1.3.6.1.4.1.59719.0.5.10, 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:
链路中断通知。接口或链路进入 down 状态时上报。
状态：已注册但未使用。尚无设备上报过本通知。首次使用前应定义用于区分真实故障与物理层瞬时抖动的去抖时延。本文件每次修订时须重新核验该未使用状态。
建议：应携带接口对象、变更前后状态以及可获得的中断原因，并与 1.3.6.1.4.1.59719.0.5.10 建立关联，避免短时抖动留下常开告警。
关联节点：1.3.6.1.4.1.59719.0.5、1.3.6.1.4.1.59719.0.5.10、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。
