shows the Telnet server and client configuration required for a successful Telnet login.
Table 5 Telnet server and Telnet client configuration requirements
Device role
Requirements
Telnet server
Enable Telnet server.
Configure the IP address of a Layer 3 interface, and make sure the Telnet server and
client can reach each other. By default, the LB module has the IP address
192.168.0.1/24 configured for the interface GigabitEthernet 0/1 and L1000-A has
the same IP address configured for the interface GigabitEthernet 0/0.
Configure the authentication mode and other settings.
Telnet client
Run the Telnet client program.
Obtain the IP address of the Layer 3 interface on the server.
To control Telnet access to the LB product operating as a Telnet server, configure login authentication and
user privilege levels for Telnet users.
By default, scheme authentication applies to Telnet login, but no login password is configured. To allow
Telnet access to the LB product 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. This mode is insecure.
•
Password—Requires a password for accessing the CLI. If your password was lost, log in to the LB
product through the console port to re-set 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 LB product through the console port and re-set the password. If the
username or password configured on a remote server was lost, contact the server administrator for
help.
