Server communication
Shared IP - same subnet
In a FortiNAC Control Server and FortiNAC Application Server configuration that uses a shared IP, the FortiNAC Application Server appliances are separate standbys from the FortiNAC Control Server appliances.
Examples:
- If the primary FortiNAC Control Server fails, the secondary FortiNAC Control Server communicates with whichever FortiNAC Application Server is in control (either the primary or the secondary).
- If the primary FortiNAC Application Server fails, the primary FortiNAC Control Server communicates whichever FortiNAC Application Server is in control.
No shared IP - different subnets
In a FortiNAC Control Server and FortiNAC Application Serverconfiguration that does not use a shared IP, the FortiNAC Application Server and FortiNAC Control Server appliances failover in pairs.
Examples:
- If the primary FortiNAC Control Server fails the primary FortiNAC Application Server is also brought down and the secondary pair of appliances take control.
- If the primary FortiNAC Application Server fails, the primary FortiNAC Control Server is also brought down and the secondary pair of appliances take control.
