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 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.
Specify a password (up to 32 alphanumeric characters) as the key to be shared between
the external RADIUS server and the Switch. This key is not sent over the network. This key
must be the same on the external RADIUS server and the Switch.
