Recovering a Replica After a Failed Download

If a Replica RADIUS Server fails during the download of a configuration 
package, its configuration may be corrupted or it may have a stale secret. For 
information on how to recover a Replica after a failed download, refer to 

“Recovering a Replica After a Failed Download” on page 70

.

Changing the Name or IP Address of a Server

To change the DNS name or IP address of a Primary or Replica RADIUS Server, 
you run the 

rsainstalltool

 (Windows) or the 

rsaconfiguretool

 

(Solaris/Linux) utility. For more information, refer to 

“Changing the Name or IP 

Address of a Server” on page 71
