我使用的是 R630 和 Debian 11，以及 Ex2200 版本12.3R12.4
网络：每台服务器使用4个链接到sw
server 1 ==== switch ==== server 2
这是服务器配置（两个服务器）

然后我使用 iperf3 检查速度，结果 tcp 和 udp 都是 1Gbps。
但链接状态显示I'm 4Gbps
所有端口均显示相同的 MAC 地址

据我所知，上次用华为交换机的时候有一个选项load-balance src-dst-mac是key，可以实现速度叠加。
但我在JunOS中没有找到任何相关配置。
问题：如何配置 LACP 或哈希或任何影响 JunOS 中的 LB 的机制？
答案1
我将从我在其他地方读到的另一篇文章中窃取你的问题的答案：
一个简单粗暴的解释是，使用 LACP 的单条通信线路不会将数据包拆分到多个接口上。例如，如果您有一个从 HostA 到 HostB 的单个 TCP 连接流式传输数据包，它将不会跨接口发送这些数据包。最近我一直在研究 LACP 以寻找我们正在研究的解决方案，这是一个常见的误解，即使用 LACP“绑定”或“中继”多个网络接口会为您提供组合接口的“吞吐量”。一些供应商已经制作了专有驱动程序，可以通过多个接口进行路由，但据我所知，LACP 标准并非如此。
