A. Fast roaming is a feature where the client's credentials are not sent to the Authentication server every time the client authenticates. Once a client authenticates to an AAA server, credentials are cached in the AP. The next time a client roams, the AP authenticates and supplies the credentials by itself to the client without sending it back to the AAA server. This saves time and enables faster roams of clients. For more information on fast roaming, refer to the Understanding Fast Secure Roaming section of Configuring WDS, Fast Secure Roaming, and Radio Management.
