Cluster Mode
In Enterprise Licensing, the system can run with up to five other controllers in a cluster. For this purpose, the list of peering partners (devices) must be entered on each controller. The entry is made as a list of IP addresses.
One controller must be declared the master. The configurations (blacklists/whitelists, system settings, etc.) are replicated from this master to the other systems.
You need at least one Enterprise Controller for the functionality.
