Securing Access to Management Functions
December 2000 3 - 39
When you configure authentication-method lists for RADIUS, you must create a separate authentication-method
list for Telnet or SSH CLI access and for CLI access to the Privileged EXEC level and CONFIG levels of the CLI.
To create an authentication-method list that specifies RADIUS as the primary authentication method for securing
Telnet access to the CLI:
BigIron(config)# enable telnet authentication
BigIron(config)# aaa authentication login default radius local
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:
BigIron(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 Foundry 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 3.5: 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. See “Setting a Telnet Password” on page 3-9.
enable Authenticate using the password you configured for the Super User
privilege level. This password is configured using the enable super-
user-password… command. See “Setting Passwords for Management
Privilege Levels” on page 3-10.
local Authenticate using a local user name and password you configured on
the device. Local user names and passwords are configured using the
username… command. See “Configuring a Local User Account” on
page 3-13.
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.
