Using the FortiController-5103B mgmt interface as a heartbeat interface
The FortiController-5103B can use the following command to add the mgmt interface to the list of heartbeat interfaces used. This example adds the mgmt interface for heartbeats to the B1 and B2 interfaces. The B1 and B2 ports are recommended because they are 10G ports and the Mgmt interface is a 100Mb interface.
