Usage
Information
For RADIUS over TLS authentication, configure the radsec shared key on the server and OS10
switch. The show running-configuration output displays both the unencrypted and encrypted
key in encrypted format. Configure global settings for the timeout and retransmit attempts allowed
on a RADIUS over TLS servers using the radius-server retransmit and radius-server
timeout commands. The no version of this command removes a RADIUS server from RADIUS over
TLS communication.
RADIUS over TLS authentication requires that X.509v3 PKI certificates are configured on a certification
authority and installed on the switch. For more information, including a complete RADIUS over TLS
example, see xref="X.509v3 certificates".
