XThe RADIUS shared secret to be used by the RSA RADIUS Server and the client device. For information on RADIUS shared secrets, see “Shared Secrets” on page 6.
XThe UDP ports on which to send and receive RADIUS authentication and accounting packets. RSA RADIUS Server uses UDP ports 1645 and 1812 for authentication and UDP ports 1646 and 1813 for accounting. For more information, see “RADIUS Ports” on page 8.
Shared Secrets
A shared secret is a text string that serves as a password between hosts.
RSA RADIUS Server uses three types of shared secrets:
XRADIUS secret – Used to authenticate communication between a RADIUS server and a RADIUS client
XReplication secret – Used to authenticate communication between a primary RADIUS server and a replica RADIUS server
XNode secret – Used to authenticate communication between a RADIUS server and an RSA Authentication Manager server.
