17.7 Technical Reference
This section provides some technical background information about the topics
covered in this chapter.
A trusted AP is an AP that uses the NWA’s internal RADIUS server to authenticate
its wireless clients. Each wireless client must have a user name and password
configured in the
AUTH. SERVER > Trusted Users screen.
The following figure shows how this is done. Wireless clients make access requests
to trusted APs, which relay the requests to the NWA.
Figure 128 Trusted APs Overview
Take the following steps to set up trusted APs and trusted users.
1
Configure an IP address and shared secret in the Trusted AP database to specify
an AP as trusted.
2
Configure wireless client user names and passwords in the Trusted Users
database to use a trusted AP as a relay between the NWA’s internal RADIUS
server and the wireless clients.
The wireless clients can then be authenticated by the NWA’s internal RADIUS
server.
PEAP (Protected EAP) and MD5 authentication is implemented on the internal
RADIUS server using simple username and password methods over a secure TLS
connection. See
Appendix B on page 319 for more information on the types of EAP
authentication and the internal RADIUS authentication method used in your NWA.
