Table 47 Advanced Application > Auth and Acct > 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-priorityand 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-robinto 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-priorityfor 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.
