Login Authentication - Dell PowerConnect 6024F Command Line Interface Reference Manual

radius
Default Configuration
If the default list is not set, only the enable password is checked. This has the same effect as
the command aaa authentication enable default enable.
On the console, the enable password is used if it exists. If no password is set, the process still
succeeds. This has the same effect as using the command aaa authentication enable default
enable none.
Command Mode
Global Configuration mode
User Guidelines
The default and optional list names created with the aaa authentication enable command are
used with the enable authentication command.
Create a list by entering the aaa authentication enable list-name method command 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. Spaces cannot be used in the
string which defines the list-name.
NOTE:
Make sure that the given sequence of authentication methods is sensible. For example, a
sequence where Radius follows None is not sensible because None requires no authentication and,
therefore, the process will never require Radius authentication.
All aaa authentication enable default requests sent by the router to a RADIUS server include
the username "$enabx$.", where x is the requested privilege level.
Example
The following example sets authentication when accessing higher privilege levels.
Console (config)# aaa authentication enable default enable

login authentication

The login authentication line configuration command specifies the login authentication method
list for a remote telnet or console. To return to the default specified by the authentication login
command, use the no form of this command.
Uses the list of all RADIUS servers for authentication. Uses username
"$enabx$." where x is the privilege level.
