Issue

The host with the 12.4.0.0 version does not retain its IP after rebooting. 

Cause

This issue occurs because the NM_CONTROLLED parameter is set to no on the host.

Resolution

To resolve the issue, you must update the NM_CONTROLLED parameter to yes on the host where the failure occurs. You can do this by following these steps:

1. vi /etc/sysconfig/network-scripts/ifcfg-<INTERFACE>

   
   For example, 

   vi /etc/sysconfig/network-scripts/ifcfg-em1

2. Set the NM_CONTROLLED parameter to yes (NM_CONTROLLED=yes)
3. Restart the NetworkManager and network services by running the following command: 

   systemctl restart NetworkManager && systemctl restart network
