LACP NIC Bonding 在哈希策略第 2+3 层始终只使用一个接口端口事件

我们在 UBUNTU 20.04 NIC 绑定 LACP 802.3ad 时遇到了问题。两个 100G NIC 端口通过 netplan 绑定，设置是 - MTU 9216、哈希策略 2+3、LACP 快速，并且从 100G 交换机配置相同。

我们使用了iperf多达 24 个多处理器线程，但nload测试显示只有一个 NIC 接口已饱和，即 92Gbps，并且从未超过该值。请分享您的想法。（附上一些屏幕截图）

回答我的问题，请在交换机绑定接口和服务器绑定接口之间添加相同的哈希算法。例如，如果交换机配置为 3+4 传输哈希策略，则在服务器操作系统中保持相同。

设置哈希策略的命令：

echo layer3+4 > /sys/class/net/bond3/bonding/xmit_hash_policy

谢谢，Aagi
