Controlled failover between wireless controllers

Controlled failover between wireless controllers

1+1 Wireless Controller HA

Instances of failover between FortiAP units was too long and lead to extended periods of time where WiFi users were without network connection. Because WiFi is considered a primary network connection in today’s verticals (including enterprise, retail, education, warehousing, healthcare, government, and more), it is necessary for successful failover to occur as fast as possible.

Primary and secondary ACs

You can now define the role of the primary and secondary controllers on the FortiAP unit, allowing the unit to decide the order in which the FortiAP selects the FortiGate. This process was previously decided on load-based detection, but can now be defined by each unit’s pre-determined priority. In addition, heartbeat intervals have been lowered to further improve FortiAP awareness and successful failover.

1+1 redundancy

1+1 HA is a form of resilience whereby a component has a backup component to take its place in the event of component failure, and successfully manage FortiAP without long failover periods.
