带 vlan dhcp 的 netplan 不分配地址

  • 772

我有一个带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，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（意味着 enp3s0.108）

顺便说一句，我不知道netplan的错误消息来自哪里。

dhcp

    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获得了 DHCP 地址。
