If you also want to specify which FortiSwitch module is used as the primary or
failover, its priority must be greater than the failover interface, or it must have a
higher position in the Heartbeat Interface list. Position in the Heartbeat Interface
list varies by the model of the FortiGate modules.
You can satisfy these requirements in multiple ways by adjusting interface priority
or by disabling heartbeats over other interfaces. Required steps vary by the model
of your FortiGate modules, and the number and Heartbeat Interface list position of
other interfaces enabled as HA heartbeat interfaces.
