NetWitness appliance network interface fails to start after rebooting the 12.4.0.0 host.

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
