Bond 无法在 Ubuntu Server 20.04 上获取 DHCP 租约

我最近安装了 Ubuntu Server 20.04 来替换 ESXi 服务器。在安装过程中，我为两个以太网接口配置了一个绑定接口。我将 ZyXel GS1900-8 上的键配置为静态 LAG。在设置过程中，链接成功建立并通过 DHCP 租用了 IP。

所有后续引导都未能获取绑定接口的 IP 地址。有时，如果我在被奴役的接口上允许 dhcp4 并运行sudo dhclient -r && sudo dhclient，被奴役的接口将被租用一个 IP 地址，并且绑定将获得一个 IP 地址。我知道这是不合适的，因为 dhclient 和 systemd-networkd 不能混合使用。

另外，我想将其配置为 LACP 绑定。我在交换机上启用了 LACP，优先级为 65535 和“IP/MAC 地址”负载平衡算法，将 LAG 从静态切换到 LACP，并更改了 netplan 以使用 802.3ad 绑定模式。

请让我知道我在这里做错了什么，如果有的话。我在这里查看了尽可能多的 netplan DHCP 绑定帖子，但无济于事。有关配置文件和命令输出，请参见下文。
