Controller clusters enable seamless roaming of clients between AP and ensure service continuity in the event of a failover. Controller clustering is supported only on devices running ArubaOS 8.x or later software versions. To view the cluster components, expand the cluster in the Cluster Name column.

By All—Displays a complete list of controllers.

A single Mobility Master or a cluster of Mobility Masters oversees co-located controllers. It also displays the details about the APs associated with each controller.
