Table 48 Advanced Application > Auth and Acct > TACACS+ Server Setup

LABEL	DESCRIPTION
Authentication	Use this section to configure your TACACS+ authentication settings.
Server

Mode	This field is only valid if you configure multiple TACACS+ servers.
	Select index-priorityand the Switch tries to authenticate with the first configured
	TACACS+ server, if the TACACS+ server does not respond then the Switch tries to
	authenticate with the second TACACS+ server.
	Select round-robinto alternate between the TACACS+ 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 TACACS+ server.
	If you are using index-priorityfor your authentication and you are using two
	TACACS+ servers then the timeout value is divided between the two TACACS+
	servers. For example, if you set the timeout value to 30 seconds, then the Switch
	waits for a response from the first TACACS+ server for 15 seconds and then tries
	the second TACACS+ server.

Index	This is a read-only number representing a TACACS+ server entry.

IP Address	Enter the IP address of an external TACACS+ server in dotted decimal notation.

TCP Port	The default port of a TACACS+ server for authentication is 49. You need not
	change this value unless your network administrator instructs you to do so.
