Point
The takeover virtual interface and the logical interface are displayed differently depending on the OS.
For RHEL7
When using the physical interfaces eth1 and eth2, the takeover virtual interface and the logical interface are eth1:1 and eth2:2.
For RHEL8 or later
When using the physical interfaces eth1 and eth2, the takeover virtual interface and the logical interface are displayed as the secondary address of eth1 and eth2 by the ip command.
