netplan 配置不应用以太网 LAN

电源循环后，我无法看到具有ifconfig以下 netplan 配置的以太网接口。 ethMine显示在ip link show，但未上升。

$ cat /etc/netplan/01-netcfg.yaml 
network:
  version: 2
  renderer: networkd
  ethernets:
    enp38s0f1:
      addresses: [192.168.1.21/24]
      match:
        macaddress: 80:fa:5b:xx:xx:xx
      set-name: ethMine
      nameservers:
        addresses: [8.8.8.8, 8.8.4.4]
      optional: true
  vlans:

      link: ethMine

      access-points:
        "myssid":
          password: "mypasswd"
  • 在 Ubuntu 桌面上。
  • 没有其他 netplan 配置。
  • /etc/network/interfaces被注释掉了
$ dmesg | grep ethMine
[    2.881002] r8169 0000:26:00.1 ethMine: renamed from enp38s0f1

重新启动时，我看到ethMine了ip link show，但它没有启动，在 中也不可见ifconfig。 ethMine.200不存在。

sudo systemctl restart systemd-networkd原因ethMine已解决，但仍然没有带有日志的 vlan：

netplan.io桌面版本Ubuntu 18.04.4 LTS：

$ dpkg -s netplan.io | grep '^Version:'
Version: 0.99-0ubuntu3~18.04.3

这些手动步骤在启动后起作用：

sudo ip link set enp38s0f1 down
sudo ip link set enp38s0f1 name ethMine
sudo ip link set ethMine up
sudo ip addr add 192.168.1.21/25 dev ethMine

sudo ip link add link ethMine name ethMine.200 type vlan id 200
sudo ip addr add 192.168.1.121/26 dev ethMine.200
sudo ip link set dev ethMine.200 up

答案1

/etc/network/interfaces应该看起来像这样...

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

/etc/netplan/01-netcfg.yaml应该看起来像这样...
