R3303-HP HSR6800 Routers Fundamentals Configuration Guide

By default, you can log in to the device through modems without authentication and have user privilege
level 0. To improve device security, configure AUX login authentication.
The following are authentication modes available for modem dial-in through the AUX port:
• None—Requires no authentication and is insecure.
• Password—Requires a password for accessing the CLI. If your password was lost, log in to the
device through the console port to view or modify the password.
• Scheme—Uses the AAA module to provide local or remote authentication. If your username or
password was lost, log in to the device through the console port to view or modify the setting. If the
username or password configured on a remote server was lost, contact the server administrator for
help.
