Table 79 Advanced Application > AAA > RADIUS Server Setup
LABEL DESCRIPTION
Authentication Use this section to configure your RADIUS authentication settings.
Server
Mode 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.
Timeout 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.
Index This is a read-only number representing a RADIUS server entry.
IP Address Enter the IP address of an external RADIUS server in dotted decimal notation.
UDP Port 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.
Shared Secret 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.
Note that as you type a password, the screen displays an asterisk (*) for each character you
type.
