The following table describes the labels in this screen.
Table 33 Network > Wireless LAN > General: WPA/WPA2
LABEL DESCRIPTION
WPA Compatible This check box is available only when you select WPA2-PSK or WPA2
in the Security Mode field.
Select the check box to have both WPA2 and WPA wireless clients be
able to communicate with the NBG-460N even when the NBG-460N is
using WPA2-PSK or WPA2.
ReAuthentication
Timer (in
seconds)
Specify how often wireless stations have to resend usernames and
passwords in order to stay connected. Enter a time interval between
10 and 9999 seconds. The default time interval is 0 or no
reauthentication.
Note: If wireless station authentication is done using a RADIUS
server, the reauthentication timer on the RADIUS server
has priority.
Idle Timeout The NBG-460N automatically disconnects a wireless station from the
wired network after a period of inactivity. The wireless station needs
to enter the username and password again before access to the wired
network is allowed. The default time interval is 3600 seconds (or 1
hour).
Group Key
Update Timer
The Group Key Update Timer is the rate at which the AP (if using
WPA-PSK/WPA2-PSK key management) or RADIUS server (if using
WPA/WPA2 key management) sends a new group key out to all
clients. The re-keying process is the WPA/WPA2 equivalent of
automatically changing the WEP key for an AP and all stations in a
WLAN on a periodic basis. Setting of the Group Key Update Timer is
also supported in WPA-PSK/WPA2-PSK mode. The NBG-460N
default is 1800 seconds (30 minutes).
Authentication Server
IP Address Enter the IP address of the external authentication server in dotted
decimal notation.
Port Number Enter the port number of the external authentication server. The
default port number is 1812.
You need not change this value unless your network administrator
instructs you to do so with additional information.
Shared Secret Enter a password (up to 127 alphanumeric characters) as the key to
be shared between the external authentication server and the NBG-
460N.
The key must be the same on the external authentication server and
your NBG-460N. The key is not sent over the network.
Accounting Server
Active Select Yes from the drop down list box to enable user accounting
through an external authentication server.
IP Address Enter the IP address of the external accounting server in dotted
decimal notation.
