A sensor or hybrid appliance must be enrolled in a cluster. The Central Management appliance that manages the IVX cluster provides the enrollment service for the sensors and hybrid appliances and the cluster. A cluster uses the enrollment service to publish its identity, capacity, and capabilities. A sensor or hybrid appliance uses the enrollment
service to enroll with a cluster based on matching criteria and available capacity. The sensors and hybrid appliances and the brokers use the enrollment service to authenticate with each other for secure communication.
Automatic enrollment is enabled by default. After a sensor or hybrid appliance is connected to a Central Management appliance with at least one cluster, the sensor is automatically enrolled with the cluster that has the most capacity, and is connected to a dedicated broker in the cluster. The enrollment is permanent—submissions are distributed between brokers in the same cluster, but not between clusters. If sensors are not managed by the Central Management appliance that manages the IVX cluster, you must configure the enrollment service as described in Enrolling a managed sensor directly.
