我有一个具有两个物理网络接口的设备，enp2s0 和 enp3s0！
所有通信都应分配给 VLAN。
该设备运行 ubuntu 并且是 KVM 系统的主机，因此也定义了一个桥接器。

由于某种原因，enp3s0.108 没有分配 ip 地址。

我很感激任何可能设置错误的提示。
更新：当我查看我的 DHCP 服务器时，IP 地址被分配给 MAC 地址：00：01：2e：93：a9：89（表示 enp3s0.108）
顺便说一句，我不知道 netplan 的错误信息来自哪里。
答案1
当您将接口添加到网桥时，通常需要在网桥接口上进行 IP 配置，而不是底层物理接口（或在本例中为 vlan）。网桥的本质是，网桥中的所有接口只有一个 IP 层（第 3 层）配置。
出于调试目的，您可能需要检查在未将 vlan 接口添加到网桥时是否在 vlan 接口上获取 DHCP 地址。
