監視介面連結是否根據接收到的 SNMP 設陷頻繁地啟動及關閉
此監視會指出裝置目前是否出現 Flapping 的現象;亦即從可用狀態快速切換成無法使用狀態。 此監視有兩種可能的狀態:
狀況良好: 裝置未出現 Flapping 現象
錯誤: 裝置出現 Flapping 現象
此監視處於錯誤狀態時,表示介面出現 Flapping 現象,也就是從可用狀態快速切換成無法使用的狀態。
請使用健全狀況總管,在監視的 [狀態變更事件] 索引標籤上查看狀態變更的詳細資料。 此資料顯示裝置回應查詢時所傳回的物件識別碼 (OID) 和值。 請針對裝置的特定 OID 參考裝置製造商的文件,以取得有關問題和疑難排解程序的詳細資訊。
