Therefore, if the parameter was configured as ' ONBOOT = no', when executing the command ' systemctl restart rvice', the interface will not assign an IP and it will appear that this command does not work. The configuration file is called 50-cloud-init.yaml and is located in /etc/netplan. The ONBOOT parameter does not only apply when the server boots, but when the network service is started. Each failover IP address will need its own line in the configuration file. #ip add show (to verify if the change was applied) #vi /etc/sysconfig/network-scripts/(put the file to configure example:ifcfg-enp0s3, ifcfg-lo) The ip add command will request the IP address of the system: Please find more details as you read below.
