我/etc/sysconfig/network-scripts/在 RHEL 上有 3 個網路：
ifcfg-lan0 ifcfg-lan1 ifcfg-lo
ip a將列出這些資訊：
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
....
我想刪除lan1。
我刪除了ifcfg-lan1下/etc/sysconfig/network-scripts/。
運行$ sudo ip link delete lan1得到：
RTNETLINK answers: Operation not supported
重啟網路服務
sudo systemctl restart network
重新啟動系統然後得到：
$ 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？
