This window lets you view and define the RADIUS servers used in your Extreme Management Center applications. RADIUS servers can be used in Management Center server authentication configurations and in NAC Manager AAA configurations.
You can access this window from the Users/Groups tab in the Authorization/Device Access tool, or in NAC Manager from the AAA Configuration window. Any changes made in this window are written immediately to the Management Center database.
