我遇到标题中提到的 NX9000 端口通道配置到 Debian 服务器 Bond 配置的问题。 NX 上的端口通道中配置的 3 个接口中的 2 个（让我们调用 NX1）已挂起（接口上看不到 LACP PDU）。
为了提供有关设置的想法，我有 2 个 NX9000（我们称它们为 NX1 和 NX2）通过 VPC 对等互连连接，并且连接到服务器的 VPC 已正确配置。在 NX1 到 debian 服务器上，端口通道中的接口如下所示：
NX1# sh int status | i sus
Eth1/3 CDN temp 2 suspended trunk auto auto 10Gbase-SR
Eth2/20 CDN temp 1 suspended trunk auto auto 10Gbase-SR
在 lacp 邻居信息中，我们看到以下内容（我确实注意到有问题的邻居接口处于 SP 模式）：
ELSO-TV01# sh lacp neighbor interface port-channel 4
Flags: S - Device is sending Slow LACPDUs F - Device is sending Fast LACPDUs
A - Device is in Active mode P - Device is in Passive mode

为了说明所发生的情况，端口通道 4 之前已启动并工作，但意外断电，导致 Debian 服务器短时间离线。启动后，我们仅在这些接口连接到服务器时遇到此问题。
（思科支持人员确认交换机端配置没有问题）。
这是提供商能够发送的内容（以下 6 个接口中有 4 个处于打开状态，两个处于关闭状态的是 enp131s0f1 和 enp2s0f0）。下面给出了绑定中工作接口和非工作接口的配置片段。
