3.3.1 aaa authentication login

The aaa authentication login global configuration command defines login authentication. To return to the default
configuration, use the no form of this command.
Syntax
aaa authentication login {default | list-name} method1 [method2...]
no aaa authentication login {default | list-name}
§ Default — Uses the listed authentication methods that follow this argument as the default list of methods when a
user logs in.
§
list-name—Character string used to name the list of authentication methods activated when a user logs in.
§
method1 [method2...]—Specify at least one from the following table:
Keyword Source or destination
enable Uses the enable password for authentication.
line Uses the line password for authentication.
local Uses the local username database for authentication
none Uses no authentication.
radius Uses the list of all RADIUS servers for authentication. Uses username
tacacs Uses the list of all TACACS servers for authentication. Uses username
Default Configuration
The local user database is checked. This has the same effect as the command aaa authentication login listname local .
Note: On the console, login succeeds without any authentication check if the authentication method is not defined.
Command Mode
Global Configuration mode
User Guidelines
The default and optional list names created with the aaa authentication login command are used with the login
authentication command.
Create a list by entering the aaa authentication login list-name method command for a particular protocol, where
list-name is any character string used to name this list. The method argument identifies the list of methods that the
authentication algorithm tries, in the given sequence.
The additional methods of authentication are used only if the previous method returns an error, not if it fails. To ensure that
the authentication succeeds even if all methods return an error, specify none as the final method in the command line.
Example
The following example configures authentication login.
console (config) # aaa authentication login default radius local enable none
example, the command interface range port-channel has the option of either
entering a range of channels, or selecting all. When the command is entered
without a parameter, it automatically defaults to all.
