When the “WPA2 Only” is checked, only Clients with WPA2 support are allowed access to the
WLAN.
When the “AES Only” is checked, only Clients with AES support are allowed access to the WLAN.
Cisco LEAP protocol (not CMIC & CKIP) is supported under “WEPxxx & 802.1x Authentication”.
Multiple RADIUS and RADIUS redundancy
RADIUS is a common authentication protocol utilized by the 802.1x security standard (often used
in wireless networks). Although RADIUS was not initially intended to be a wireless security
authentication method, it improves the WEP encryption key standard, in conjunction with other
security methods such as EAP-PEAP.
In an enterprise environment, several RADIUS servers may be used for backup and also for serving
different geographical locations. Up to four different RADIUS servers can be defined for each
SSID. RADIUS redundancy is based on the assumption that the user database is identical in all
RADIUS servers and that users are listed in all servers with the same credentials.
Switchover from one RADIUS server to another takes place after consecutive failures of the server.
The order of priorities is 1 to 4.
