我/etc/sysconfig/network-scripts/在 RHEL 上有 3 个网络：
ifcfg-lan0 ifcfg-lan1 ifcfg-lo
ip a将列出这些信息：
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
....
2: lan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc mq state UP group default qlen 1000
....
3: lan1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc mq state UP group default qlen 1000
....
我想删除lan1。
我删除了ifcfg-lan1下/etc/sysconfig/network-scripts/。
运行$ sudo ip link delete lan1得到：
RTNETLINK answers: Operation not supported
重启网络服务
sudo systemctl restart network
重新启动系统然后得到：
$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
....
2: lan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc mq state UP group default qlen 1000
....
3: lan1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
....
如何去除lan1？
