链路聚合问题 (LACP)

Question

我在 Ubuntu 20.04 上运行 nextcloud 服务器，并设置了链路聚合。除非服务器正在使用中，否则它似乎无法正常工作。例如，如果我在服务器上运行速度测试，我可以在本地 ping 服务器，但是当我关闭服务器上的 Web 浏览器时，我甚至无法在本地 ping 服务器，或者有时是间歇性的。另一个问题是，当通过 SSH 连接到服务器时，它要么根本不起作用，要么工作时滞很大。

这是我的 /etc/network/interfaces：

auto enp1s0
iface enp1s0 inet manual
bond-master bond0

auto enp3s0
iface enp3s0 inet manual
bond-master bond0

auto bond0
iface bond0 inet static
    address 192.168.1.155
    gateway 192.168.1.1
    netmask 255.255.255.0
    dns-nameservers 1.1.1.1 1.0.0.1
    slaves enp1s0 enp3s0
    lacp-rate fast
    bond-mode 4
    bond-miimon 100
    bond-slaves none

这是 cat /proc/net/bonding/bond0
