Using the LAN1 and LAN2 interfaces it is possible to perform an Active Passive configuration to achieve high availability.
Is it possible to do something similar for the Management interface?
Infoblox MGMT port does not support a VIP as of today. Thus you cannot backup the MGMT port with another port within the same Infoblox server(as what you're looking for) in order to accommodate a failure. In case of an HA pair where two Infoblox servers are configured to act as a single node, you may be able to get some sort of redundancy. However the idea of a single MGMT IP address bouncing between two physical addresses might still be unworkable.
