Passphrase
Setting Description Factory Default
8 to 63 characters Master key to generate keys for encryption and decryption None
Key renewal (for AP/Master mode only)
Setting Description Factory Default
60 to 86400 seconds
(1 minute to 1 day)
Specifies the time period of group key renewal 3600 (seconds)
NOTE
The
key renewal value
dictates how often the wireless AP encryption keys should be changed. The security level
is generally higher if you set the
key renewal
value to a shorter number, which forces the encryption keys to be
changed more frequently. The default val
ue is 3600 seconds (6 minutes). Longer time periods can be
considered if
the line is not very busy.
WPA/WPA2-Enterprise (for AP/Master mode)
By setting WPA type to 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 on a large-scale network. It is not necessary to exchange keys or
passphrases.
