Q23. Why would you enable the RFC 3578 option when adding a new RADIUS authentication server to a WLC? 

A. you want to run both RADIUS and TACACS 

B. to support Disconnect and Change of Authorization 

C. to encrypt communications between the WLC and the RADIUS server 

D. to support RADIUS key wrapping 

Answer:

Explanation: 

If you are configuring a new RADIUS authentication server, choose Enabled from the Support for RFC 3576 drop-down list to enable RFC 3576, which is an extension to the RADIUS protocol that allows dynamic changes to a user session, or choose Disabled to disable this feature. The default value is Enabled. RFC 3576 includes support for disconnecting users and changing authorizations applicable to a user session and supports disconnect and change-of-authorization (CoA) messages. Disconnect messages cause a user session to be terminated immediately where CoA messages modify session authorization attributes such as data filters.
