ECS Ubuntu system individually disables and starts internal and external network card commands

You can use [ifdown network card] and [ifup network card] to individually disable or enable a certain network card.

The [ifconfig] command under the Ubuntu system can check the network card status

To disable the intranet network card, you can use ifdown eht0 to disable it. After disabling it, ifconfig cannot see it. The internal network is stuck.

To enable the intranet network card, you can use ifup eth0 to start it, and then use ifconfig to query whether the intranet network card is activated.

If you want to disable or enable the public network card, replace eth0 in the command with eth1.
