Import Cluster Config to import an existing cluster configuration. If you select a cluster before you Import Cluster Config, the Controller and Cluster are automatically populated with the appropriate information for the selected cluster. If you do not select a cluster before you Import Cluster Config, then you must select the Controller and the Cluster populates automatically based on the Controller node you select.After you import the configuration, Commit to Panorama to save the imported candidate configuration in the Panorama running configuration. If you no longer need to manage a WildFire cluster from Panorama, Remove From Panorama and select Yes to confirm your action. After you remove a cluster from Panorama management, you can manage the cluster locally from a Controller node. You can add the cluster back in to the Panorama appliance at any time if you want to again manage the cluster centrally instead of locally. To encrypt data communication between WildFire appliances in a cluster, Enable encryption under Secure Cluster Communication.WildFire uses either a predefined certificate or a custom certificate to communicate between appliances. Custom certificates are only used when you Customize Secure Server Communication and enable Custom Certificate Only.
