The Primary RADIUS Server maintains a list of the Replica RADIUS Servers that have registered with it. The Primary RADIUS Server uses this list to track which servers to notify after it publishes an updated configuration package to resynchronize the configuration of Replica RADIUS Servers.

Replacing a Replica RADIUS Server
To replace a failed Replica RADIUS Server, a network administrator shuts down the failed server, installs the RSA RADIUS Server software on a replacement server, and enables the Replica RADIUS Server. The Replica RADIUS Server then downloads and installs its configuration package from the Primary RADIUS Server.
Designating a New Primary RADIUS Server
You can change which server within a realm is designated as the Primary RADIUS Server for that realm. For more information, see “Designating a New Primary RADIUS Server” on page 70.
