RADIUS Authentication Process A-3
If at any point in the authentication process conditions are not
met, the RADIUS server sends an authentication rejection to the
LX unit and the user is denied access to the network.
Figure 2.A.1, “RADIUS Authentication Process” shows an
example of the RADIUS authentication process.
Figure A.1 RADIUS Authentication Process
The LX implementation of RADIUS supports the use of RADIUS
secondary servers. The RADIUS secondary server is used when
the RADIUS primary server can’t be accessed.
