User Guide: AT-RADGate for VST-APL/VST-VRT version 1.2.0

# Redundant configuration considerations

The RADIUS Server provides authentication services, so if the RADIUS Server cannot respond to authentication requests from the NAS, the supplicant is likely unable to connect to the network.
AT-RADgate registers an authentication policy, but does not have the ability to synchronize (copy) that authentication policy to another AT-RADgate. Therefore, if you install multiple AT-RADgate's (e.g. primary and secondary), you must register the authentication policy on each AT-RADgate.
Sending authentication requests to the primary and secondary RADIUS Servers must be configured on the NAS side. Refer to the NAS document for details.
