Usage Guidelines To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.

The login authentication command is a per-line command used with AAA that specifies the name of a list of AAA authentication methods to try at login.

Caution If you use a list-namevalue that was not configured with the aaa authentication login command, the configuration is rejected.

Entering the no form of the login authentication command has the same effect as entering the command with the default keyword.

Before issuing this command, create a list of authentication processes by using the aaa authentication login global configuration command.
