Ubuntu netplan arp-ip-target 问题

我有运行 netplan 版本的 ubuntu 20.04 0.102-0ubuntu1~20.04.2，我正在尝试active-backup使用选项配置绑定arp-ip-target

  bonds:
        bond0:
          dhcp4: no
          interfaces:
            - eno49
            - eno50
          parameters:
            mode: active-backup
            arp-ip-targets: [ 10.64.0.1 ]
            arp-interval: 3000

这是我的债券输出

为了进行测试，我禁用了上游交换机端口以查看我的绑定故障转移，但看起来它不起作用。我还应该解决什么问题？
