Enabling session sync and configuring the session sync interface

In a two chassis configuration you can use the following command to enable session synchronization:

config load-balance setting

set session-sync enable

end

Then for the FortiController-5103B you need to use the following command to select the interface to use for session sync traffic. The following example, sets the FortiController-5103B session sync interface to F4:

config system ha

set session-sync-port f4

end

The FortiController-5903C and FortiController-5913C use b1 and b2 as the session sync interfaces so no configuration changes are required.
