Configuring TACACS/TACACS+ security
The command above causes TACACS/TACACS+ to be the primary authentication method for
securing access to Privileged EXEC level and CONFIG levels of the CLI. If TACACS/TACACS+
authentication fails due to an error with the server, local authentication is used instead. If local
authentication fails, no authentication is used; the device automatically permits access.
Syntax: [no] aaa authentication enable | login default <method1> [<method2>] [<method3>]
The web-server | enable | login parameter specifies the type of access this authentication-method
list controls. You can configure one authentication-method list for each type of access.
NOTE
If you configure authentication for Web management access, authentication is performed each time
a page is requested from the server. When frames are enabled on the Web Management Interface,
the browser sends an HTTP request for each frame. The Dell PowerConnect device authenticates
each HTTP request from the browser. To limit authentications to one per page, disable frames on the
Web Management Interface.
The <method1> parameter specifies the primary authentication method. The remaining optional
<method> parameters specify additional methods to try if an error occurs with the primary method.
A method can be one of the values listed in the Method Parameter column in the following table.
TABLE 201

NOTE
For examples of how to define authentication-method lists for types of authentication other than
TACACS/TACACS+, refer to
Entering privileged EXEC mode after a Telnet or SSH login
By default, a user enters User EXEC mode after a successful login through Telnet or SSH.
Optionally, you can configure the device so that a user enters Privileged EXEC mode after a Telnet
or SSH login. To do this, use the following command.
