Configuring RADIUS security
26
PowerConnect(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.
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.
NOTE
For examples of how to define authentication-method lists for types of authentication other than
RADIUS, refer to “Configuring authentication-method lists” on page 907.
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.
PowerConnect(config)# aaa authentication login privilege-mode
Syntax: aaa authentication login privilege-mode
The user privilege level is based on the privilege level granted during login.
