Modem dial-in through the AUX port

An administrator can use a pair of modems to remotely connect to the device through its AUX port over

PSTN when the IP network connection is broken. To do so, make sure the dial-in connection, the device,

and the modems are correctly set up.

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.
