Mobility Controller and
Access Point Deployment
Deployment of the Mobility Controller must be considered based on a number of factors; the most
important of which is identifying where user traffic is ultimately destined. The Validated Reference
Design for Campus Wireless Networks depicts the Master Controllers residing in the data center and
Local Controllers deployed at the distribution layer.
Understanding Master and Local Operation
Once the controller count grows beyond a single pair of controllers, change control and network
consistency can become an issue. To solve this management scalability issue, Mobility Controllers can
be deployed in clusters consisting of a Master and one or more Local Controllers.
The Master Mobility Controller resides at the Management layer of the Aruba architecture in a data
center environment. In an Aruba network employing a Master/Local design, configuration is performed
on the Master and pushed down to the Locals. User troubleshooting, RF planning, and real-time RF
visualization take place on the Master. The Master also controls Adaptive Radio Management (ARM)
decisions for all Local controllers and is responsible for radio power and channel settings at the
Wireless Access layer.
