Radius events monitor emulates the back up Radius server.

To support operation in this mode, it has to reply queries of the main Radius server by valid Radius replies. Also, it has to emulate the network interface on which the "back up" Radius server listens.

The following configuration parameters must be specified to support this mode:

#Enable emulation mode
rad_server_emulation=1
#Set IP and MAC of the emulated network interface
rad_virtual_eth=172.17.69.10/D4:AE:52:C1:A7:29
#Indicate secret to form Radius replies
rad_secret=mysecretkey
