AAA Commands 83
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.
• 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.
•All
aaa authentication enable default
requests sent by the device to a RADIUS or TACACS+ server

levels.
