To configure your HA cluster with a heartbeat that fails over between the two base 
channels, both base backplane interfaces must be enabled and:

• if priorities are not equal, must have the highest priorities of all heartbeat 

interfaces

• if priorities are equal, be the first interfaces on the indexed heartbeat Interface 

list

If you also want to specify which FortiSwitch board is used as the primary or 
backup, 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 boards.

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 boards, and the number and heartbeat interface list position of 
other interfaces enabled as HA heartbeat interfaces.
