NBG-318S User's Guide
DESCRIPTION
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-318S even when the NBG-318S is using WPA2-PSK
or WPA2.
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 1800 seconds (30 minutes).
Note: If wireless station authentication is done using a RADIUS
server, the reauthentication timer on the RADIUS server
has priority.
The NBG-318S 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).
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-318S default
is 1800 seconds (30 minutes).
Enter the IP address of the external authentication server in dotted decimal
notation.
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.
Enter a password (up to 31 alphanumeric characters) as the key to be shared
between the external authentication server and the NBG-318S.
The key must be the same on the external authentication server and your NBG-
318S. The key is not sent over the network.
Select Yes from the drop down list box to enable user accounting through an
external authentication server.
Enter the IP address of the external accounting server in dotted decimal notation.
Enter the port number of the external accounting server. The default port number
is 1813.
You need not change this value unless your network administrator instructs you
to do so with additional information.
Enter a password (up to 31 alphanumeric characters) as the key to be shared
between the external accounting server and the NBG-318S.
The key must be the same on the external accounting server and your NBG-
318S. The key is not sent over the network.
Click Apply to save your changes back to the NBG-318S.
Click Reset to reload the previous configuration for this screen.
