Abstract

Methods and systems for caching of remote server MAC authentication to enable fast roaming are provided. According to one embodiment, MAC addresses of wireless client devices contained within authentication requests associated with the wireless client devices and corresponding authentication status information provided by an authentication server associated with a wireless local area network (WLAN) responsive to the authentication requests are cached by a wireless network controller of the WLAN. A MAC-based authentication request is received by the wireless network controller from a wireless access point (AP) managed by the wireless network controller on behalf of a roaming wireless client device. It is determined whether cached authentication status information exists for the MAC address of the roaming wireless client device and if so, then the roaming wireless client device is permitted or denied access to the WLAN via the AP based on the cached authentication status information.
