4.6 Virtual Controller Architecture
The Aruba IAPs use a Virtual Controller architecture for ease of deployment and centralized wireless
network management. IAPs in the same subnet will form a cluster, in each cluster a virtual controller is
elected. Normally the first IAP in the subnet will become the virtual controller. If the IAP running the virtual
controller should fail, then another IAP will elect itself as the virtual controller.
All configuration is done on the virtual controller and pushed down to all the IAPs in the cluster. All the IAPs
in the cluster will advertise the same SSIDs. Zones can be created within a cluster to specify specific SSIDs
on specific IAPs.
Entering the IP address of any access point in the cluster will redirect you to the virtual controller. You can
set the name of the virtual controller along with the virtual controller static address from the General tab of
the System dialog box, as show in Figure 8 below. The name and the IP address of the virtual controller
will always be static information no matter which IAP becomes the virtual controller.
