Key renewal (for Redundant AP, AP, or Master mode only)

Setting Description Factory Default

60 – 86400 seconds

(1 minute to 1 year)

Specifies the time period of group

key renewal

3600 (seconds)

NOTE

The value for key renewal instructs the wireless AP how often it should change the encryption

keys. Usually the security level will be higher if you set this value shorter so that the encryption

keys are changed more often. Default value is 3600 seconds (6 minutes). Longer time periods

can be considered if traffic is not so busy.

WPA/WPA2-Enterprise (for Redundant AP, AP, or Master mode)

By selecting WPA type as Enterprise, you can use EAP (Extensible Authentication Protocol), a

framework authentication protocol used by 802.1X to provide network authentication. In these

Enterprise-level security modes, a back-end RADIUS (Remote Authentication Dial-In User

Service) server is needed if IEEE 802.1X functionality is enabled in WPA /WPA2. The IEEE

802.1X protocol also offers the possibility of carrying out an efficient connection authentication in

a large-scaled network. It is not necessary to exchange keys or pass phrases.
