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 include the username $enabx$., where x is the requested privilege level.
