Table 96 Advanced Application > AAA > RADIUS Server Setup
LABEL DESCRIPTION
Authentication Use this section to configure your RADIUS authentication settings.
Server
Mode This field is only valid 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.
Delete Check this box if you want to remove an existing RADIUS server entry from the Switch. This entry
is deleted when you click Apply.
Accounting Use this section to configure your RADIUS accounting server settings.
