Ubuntu 20.04 中的网络配置

我有一台 ubuntu 20.04 服务器，发现 NetworkManager 不工作，但服务器中配置了网络

之后我检查了一下vi /etc/netplan/50-cloud-init.yaml并发现：

network:<br>
    version: 2<br>
    ethernets:<br>
        eth0:<br>
            addresses:<br>
            - 2a01:4f8:c012:b833::1/64<br>
            dhcp4: true<br>
            gateway6: fe80::1<br>
            match:<br>
                macaddress: 96:00:01:70:fb:a9<br>
            nameservers:<br>
                addresses:<br>
                - 2a01:4ff:ff00::add:2<br>
                - 2a01:4ff:ff00::add:1<br>
            set-name: eth0

这里我找不到，我的配置eth0在哪里？eth0
