16.3. 确定 NetworkManager 没有管理某个特定网络设备的原因

流程

• 显示所有网络设备的状态及其原因：

  # nmcli -f GENERAL.DEVICE,GENERAL.STATE,GENERAL.REASON device show

  如果您将设备名称传给命令，则只能显示指定设备的输出。

  输出示例：

  GENERAL.DEVICE:    enp1s0
  GENERAL.STATE:     10 (unmanaged)
  GENERAL.REASON:    75 (The device is unmanaged by explicit user decision (e.g. 'nmcli device set $DEV managed no'))
  
  GENERAL.DEVICE:    enp7s0
  GENERAL.STATE:     10 (unmanaged)
  GENERAL.REASON:    74 (The device is unmanaged by user decision in NetworkManager.conf ('unmanaged' in a [device*] section)
  
  GENERAL.DEVICE:    veth3
  GENERAL.STATE:     10 (unmanaged)
  GENERAL.REASON:    77 (The device is unmanaged via udev rule)

  注意

  请注意，命令返回所有设备的状态，无论它们是否是 managed 还是 unmanaged。
