Firepower Threat Defense FMC Loopback Address

[brandon.m.strode1]

Is there a way to set a traditional loopback address in FMC?  I would like to use a loopback address for solwarwinds management and troubleshooting but have been unable to find a way to configure one via the fmc.

The FMC is a host. And with that it has one IP that is also used for management. Same for your FTDs, the management-IP is also a host-address and can be accessed from your management-stations. This is completely different to a L3-switch or router where you can have multiple IP-interfaces with different ways to reach these interfaces.
