Table 74 Advanced Application > AAA > 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.

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

Delete	Check this box if you want to remove an existing TACACS+ server entry
	from the Switch. This entry is deleted when you click Apply.

Apply	Click Apply to save your changes to the Switch’s run-time memory. The
	Switch loses these changes if it is turned off or loses power, so use the
	Save link on the top navigation panel to save your changes to the non-
	volatile memory when you are done configuring.

Cancel	Click Cancel to begin configuring this screen afresh.

Accounting	Use this section to configure your TACACS+ accounting settings.
Server

Timeout	Specify the amount of time in seconds that the Switch waits for an
	accounting request response from the TACACS+ server.

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

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

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