Symptom
When checking 'show managers' on cluster members some or all of the FTDs may show the wrong management IP address, most likely showing the IP address of eth0.
There is also a possibility of registration failure if eth0 on the FMC is not reachable by the FTD's management interface.
Conditions
When using a clustered FTD and attempting to register to an FMC over the non default management port. For example Eth2 on the FMC
Further Problem Description
Another way to verify is to check
netstat -tuna | grep 8305
This will show active TCP connections to the wrong management IP.
