A Centralized configuration uses ExtremeWireless access points (APs). Each Wireless AP opens an IPsec tunnel to ExtremeCloud IQ Controller, and the Session Manager and RF Management policy run on ExtremeCloud IQ Controller.
A Centralized site topology allows seamless roaming within one geographic location. A single site supports multiple device groups with a total of 200 to 4,000 APs (in appliance High Availability mode) for the site. With a Centralized site, ExtremeCloud IQ Controller performs as the management server and the session manager. The RF domain manager resides locally on ExtremeCloud IQ Controller.
Although session management is centralized at the appliance, users can select the best topology for network access.
All supported ExtremeWireless AP models can be deployed in a Centralized site. See ExtremeCloud IQ Controller Managed Wireless Access Points for details.
