Modem Dial-In Through The Console Port - HP 3100 v2 Series Configuration Manual

Task
Log in to an IPv4 SSH
server.
Log in to an IPv6 SSH
server.
To work with the SSH server, you might need to configure the SSH client. For information about
configuring the SSH client, see Security Configuration Guide.

Modem dial-in through the console port

You can use a pair of modems to remotely connect to a device through its console port over the
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.
By default, you can log in to the device through modems without authentication, and have user
privilege level 3. To improve device security, configure AUX login authentication.
The following are authentication modes available for modem dial-in through the console 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 and change the password.
•
Scheme—Uses the AAA module to provide local or remote authentication. If your password
was lost, log in to the device through the console port and change the password. If the
username or password configured on a remote server was lost, contact the server administrator
for help.
