HP 6120XG 交换机 LACP 被阻止 - 错误情况

伙计们，

我正在处理与 LACP 相关的非常奇怪的问题，不确定是 6120XG 开关的错误还是其他问题。所以让我在这里解释我的问题。

网络图：

在此处输入图像描述

我在 Cisco vPC 设计中有两台 Cisco Nexus 9396PX TOR 交换机，用于连接到 HP 刀片式交换机 6120XG 的多机箱。

这是过去 1 年的生产，没有任何问题。但最近注意到我的所有 LACP 链接都关闭了，即使所有交换机都打开了。在调试期间，我发现 Cisco 交换机没有收到任何 LACP 数据包来启动这个捆绑包。（这表明 HP 6120XG 交换机有问题） 似乎 HP 交换机已冻结，或者我什至可以通过 ssh 打开来切换并运行所有命令。

HP 6120XG 固件版本：Z.14.58

Cisco Nexus 9396PX 事件期间的日志，这是我在 Cisco 和 HP 交换机上找到的日志。

重新启动 HP 刀片 6120XG LACP 后又回来了，流量开始流动，这在过去也发生在其他机架上，但每次我们只是重新启动交换机，它就会回来。（我们没有 HPE 支持，我们可以要求找出 HP 6120XG 交换机的 BUG 或我的配置中的其他内容）

LACP 是一种聚合协议。每一侧都需要为 LACP 进行配置，并且至少一侧需要主动通告聚合组才能真正形成。

您不能在 HPE 端将 Cisco VPC 与 LACP 混合使用。

在 6120XG 上，尝试trunk 18-21 Trk1 LACP active. 在 Nexus 上，您需要全局激活 LACP ( feature lacp) 并channel-group 1 mode active在每个成员接口上使用。
