11.4 Guest Wireless Screen
This screen allows you to enable and configure multiple guest wireless network settings on the
NBG6817.
You can configure up to four SSIDs to enable multiple BSSs (Basic Service Sets) on the NBG6817.
This allows you to use one access point to provide several BSSs simultaneously. You can then
assign varying security types to different SSIDs. Wireless clients can use different SSIDs to
associate with the same access point.

PMK Cache Period
This field is available only when you select

Specify how often wireless clients have to resend usernames and passwords in order
to stay connected. Enter a time interval between 10 and 999999 minutes.
Note: If wireless client authentication is done using a RADIUS server, the
reauthentication timer on the RADIUS server has priority.
Pre-Authentication
This field is available only when you select

Pre-authentication enables fast roaming by allowing the wireless client (already
connecting to an AP) to perform IEEE 802.1x authentication with another AP before
connecting to it. Select

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.
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 NBG6817.
The key must be the same on the external authentication server and your NBG6817.
The key is not sent over the network.
Session Timeout
The NBG6817 automatically disconnects a wireless client from the wireless and wired
networks after a period of inactivity. The wireless client needs to send the username
and password again before it can use the wireless and wired networks again. Some
wireless clients may prompt users for a username and password; other clients may
use saved login credentials. In either case, there is usually a short delay while the
wireless client logs in to the wireless network again.
Enter the time in seconds from 0 to 999999.
