RSA RADIUS Server 6.1 Administrator’s Guide About RSA RADIUS Server 17
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.
Figure 3 Primary and 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.
