我是 Juniper 产品的新用户，我买了两台较旧的 EX4200-48t。我设置了虚拟机箱并添加了一些带有 LACP 的 LAG。铜连接上的所有 LAG 工作正常，但 10GB 模块上却不行。模块的部件号为 740-021309 (10GBASE-LR 10km 1310nm 70C)。ae11 是带有 LACP 和两个 1G 铜上行链路的 LAG，ae48 是带有两个 SPF+ 模块的 LAG。两个 LAG 都连接到提供商交换机。我不知道他们使用的是哪个交换机。他们只告诉我，LACP 处于活动模式，不知道为什么会出现问题。

编辑1：
当我在 ae48 上禁用 LACP 时，我可以使用命令“监控流量接口 xe-0/1/0”在两个接口上看到传入的 LACP 包
当我再次激活 LACP 被动模式时，首先我看不到任何流量，过了一会儿，一个接口有时（大约每 1 分 40 秒）会收到一个 LACP 包。
