What is fast IEEE 802.1X rekeying?
A. When a client is using IEEE 802.1X, initial IEEE 802.1X authentication typically involves the access point communicating to a RADIUS server that may be in another location. When the client roams from one access point to another, the client must complete an IEEE 802.1X reauthentication, which also involves the access point communicating with a RADIUS server. The access point to RADIUS communication process can take one second or longer. With fast IEEE 802.1X rekeying, the access point executes only one single communication with the WDS (which can reside on another access point). This results in rekeying in a few milliseconds rather than the longer access point to RADIUS communication process.
