DESCRIPTION
Use this section to configure your RADIUS authentication settings.
This field only applies if you configure multiple RADIUS servers.
Select index-priority and the Switch tries to authenticate with the first configured RADIUS
server, if the RADIUS server does not respond then the Switch tries to authenticate with the
second RADIUS server.
Select round-robin to alternate between the RADIUS servers that it sends authentication
requests to.
Specify the amount of time in seconds that the Switch waits for an authentication request
response from the RADIUS server.
If you are using index-priority for your authentication and you are using two RADIUS
servers then the timeout value is divided between the two RADIUS servers. For example, if
you set the timeout value to 30 seconds, then the Switch waits for a response from the first
RADIUS server for 15 seconds and then tries the second RADIUS server.
This is a read-only number representing a RADIUS server entry.
Enter the IP address of an external RADIUS server in dotted decimal notation.
The default port of a RADIUS server for authentication is 1812. You need not change this
value unless your network administrator instructs you to do so.
