Table 13 Telnet server and Telnet client configuration requirements
Object
Telnet server
Telnet client
To control Telnet access to the device working as a Telnet server, configure authentication and user
privilege for Telnet users.
By default, password authentication applies to Telnet login, but no login password is configured. To
allow Telnet access to the device after you enable the Telnet server, you must configure a password.
The following are authentication modes available for controlling Telnet logins:
•
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. You must provide a
username and password for accessing the CLI. If the password configured in the local user
database 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.
