Enabling this option enables a client associated with one Access Point to carry out an 802.1x authentication with another Access Point before it roams over to it. The Access Point will cache the keying information of the client until it roams to the new Access Point. This enables the roaming the client to start sending and receiving data sooner by not having to do 802.1x authentication after it roams. Note: This option only works when 802.1x authentication is enabled for the WLAN.
