Cause

在 Juno 平台(DD6900、DD9400、DD9900)中,绑定接口配置与内核中的接口状态之间存在计时问题。

错误消息和错误原因代码是由于这种不匹配。

绑定接口通常会在几秒钟后进入“Running”状态并变得可用,但是,Cyber Recovery 数据避风港不会在生成错误和相应警报之前检查正在运行状态。如果遇到此问题,CR 也不会关闭接口。

Resolution

即将推出的后续版本和更高版本中提供了修复;

修复版本:DDOS-7.10.1.20DDOS-8.0.0.0、DDOS-7.13.1.0

此问题的临时解决方法是使用单个物理接口,而不是绑定接口。 但是,这意味着必须使用受保护的接口名称更新 CR 策略,以匹配新配置。请参阅有关更改策略更改前提条件的 CR 文档。此外,如果单个网络接口发生故障,此解决方法将无法保证高可用性。
