What is Fast SSID Changing?
A. Fast SSID Changing allows clients to move between SSIDs. When the client sends a new association for a different SSID, the client entry in the controller connection table is cleared before the client is added to the new SSID. When Fast SSID Changing is disabled, the controller enforces a delay before clients are allowed to move to a new SSID. For information on how to enable Fast SSID Changing, refer to the Configuring Fast SSID Changing section of the Cisco Wireless LAN Controller Configuration Guide, Release 6.0.
