我有一台具有两个网络接口的服务器。我在 /etc/systemd/network 文件夹中对其进行了如下配置：
文件：90-eth1.network
[Match]
Name=eth1
[Network]
Address=192.168.1.28/24
Gateway=192.168.1.7
DNS=8.8.8.8
DNS=8.8.4.4
文件：91-eno1.network
[Match]
Name=eno1
[Network]
Address=192.168.1.30/24
Gateway=192.168.1.7
DNS=8.8.8.8
DNS=8.8.4.4
我运行了 systemctl restart systemd-networkd。运行 systemctl status systemd-networkd 显示以下内容：

其中一个接口未连接到交换机，因此如预期的那样，它显示无运营商。我的问题是我无法使用上述配置分配静态 IP 地址。我能够通过运行“ip addr add 192.168.1.30 dev eno1”手动分配静态 IP，然后 ping 到同一网络上的另一台设备，因此我知道电缆、端口、交换机等没有硬件问题。
这是全新安装的 Linux。我之前用同样的方法安装过，并且分配了 IP 地址。这次我肯定漏掉了一些步骤。
