Configuring RADIUS security
2
The commands above cause RADIUS to be the primary authentication method for securing Telnet
access to the CLI. If RADIUS authentication fails due to an error with the server, local
authentication is used instead.
To create an authentication-method list that specifies RADIUS as the primary authentication
method for securing access to Privileged EXEC level and CONFIG levels of the CLI.
ServerIronADX(config)# aaa authentication enable default radius local none
The command above causes RADIUS to be the primary authentication method for securing access
to Privileged EXEC level and CONFIG levels of the CLI. If RADIUS 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>]
[<method4>] [<method5>] [<method6>] [<method7>]
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 ServerIron 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 11 Authentication method values
Method parameter Description
line Authenticate using the password you configured for Telnet access. The
Telnet password is configured using the enable telnet password…
command. Refer to “Setting a Telnet password” on page 100.

page 105.
tacacs Authenticate using the database on a TACACS server. You also must
identify the server to the device using the tacacs-server command.
tacacs+ Authenticate using the database on a TACACS+ server. You also must
identify the server to the device using the tacacs-server command.
radius Authenticate using the database on a RADIUS server. You also must
identify the server to the device using the radius-server command.
none Do not use any authentication method. The device automatically permits
