6.8  Layer-2 Isolation
Layer-2 isolation is used to prevent wireless clients associated with your NWA from communicating 
with other wireless clients, APs, computers or routers in a network.
In the following example, layer-2 isolation is enabled on the NWA to allow a guest wireless client 
(A) to access the main network router (B). The router provides access to the Internet and the 
network printer (C) while preventing the client from accessing other computers and servers on the 
Backup RADIUS 
Server 
If the NWA cannot communicate with the primary RADIUS server, you can have the 
NWA use a backup RADIUS server. Make sure the check box is selected if you want to 
use the backup server.
The NWA will attempt to communicate three times before using the backup server. 
Requests can be issued from the client interface to use the backup server. The length 
of time for each authentication is decided by the wireless client or based on the 
configuration of the Reauthentication Time field in the Wireless LAN > Security 
screen.
