Cause

在 Juno 平臺 (DD6900、DD9400、DD9900) 核心中,綁定介面組態和介面狀態之間出現計時問題。

錯誤消息和錯誤原因代碼是因為這種不匹配。

搭接介面通常會在幾秒鐘後進入「執行中」狀態並變成可用,但是,Cyber Recovery 不會在產生錯誤和對應的警示之前檢查執行中狀態。如果遇到此問題,CR 也不會關閉介面。

Resolution

在即將發佈的後續版本和更高版本中提供修復;

修正版本:DDOS-7.10.1.20DDOS-8.0.0.0、DDOS-7.13.1.0

暫時此問題的因應措施是使用單一實體介面,而非搭接介面。 但是,這意味著必須使用受保護的介面名稱更新CR策略以匹配新配置。請參閱有關更改策略更改先決條件的CR文件。此外,如果單一網路介面出現故障,此因應措施亦無法保證高可用性。
