RADIUS Port

application requires it.
RADIUS Key
The Radius Key is the shared secret key for the RADIUS server. The
text you enter is displayed as “*” characters to prevent others from
seeing the RADIUS key as you type.
(The AT-WA7400 Management Software internal authentication server
key is
secret .)
This value is never sent over the network.
WPA Group Rekey Interval
The interval after which the WPA encryption key is automatically
changed and authenticated between devices. The shorter the interval
is, the stronger that the encryption is. Allied Telesis recommends that
you use the default interval.

WPA/WPA2
Personal (PSK)
Wi-Fi Protected Access 2 ( WPA2 ) with Pre-Shared Key ( PSK ) is a Wi-Fi
Alliance IEEE 802.11 standard, which includes Advanced Encryption
Algorithm ( AES ), Counter mode/CBC-MAC Protocol ( CCMP ), and
Temporal Key Integrity Protocol ( TKIP ) mechanisms. The Personal
version of WPA2 employs a pre-shared key (instead of using IEEE 802.1x
and EAP as is used in the Enterprise WPA2 security mode). The PSK is
used for an initial check of credentials only.
This security mode is backwards-compatible for wireless clients that
support the original
WPA .
When you select the WPA/WPA2 Personal (PSK) security mode , the
settings in Figure 38 are displayed.
