SLBC FortiController models
Currently three FortiController models are available for session aware load balancing (SLBC).
|
The FortiController-5902D and the FortiSwitch-5203B are used for content clustering and are not compatible with SLBC. |

Splitting the FortiController-5903C and FortiController-5913C ports may require you to reset the workers to factory defaults and then completely re-configure your SLBC cluster. Fortinet recommends you split ports before configuring your cluster to save downtime due to the need to re-do your configuration. |
