24 CHAPTER 1: SYSTEM ACCESS
Configuring the Authentication Method The authentication-mode
command configures the user login authentication method that allows access to
an unauthorized user. Tabl e 11 describes the authentication-mode command.
Perform the following configuration in user interface view.
By default, terminal authentication is not required for users who log in through
the console port, whereas a password is required for authenticating modem and
Telnet users when they log in.
To configure authentication for modem and Telnet users:
1Configure local password authentication for the user interface.
When you set the password authentication mode, you must also configure a login
password to log in successfully. Table 12 describes the set authentication
password command.
Perform the following configuration in user interface view.
Configure for password authentication when a user logs in through a VTY 0 user
interface and set the password to 3Com:
[SW7750]user-interface vty 0
[SW7750-ui-vty0]authentication-mode password
[SW7750-ui-vty0]set authentication password simple 3Com
2Configure the local or remote authentication username and password.
Use the authentication-mode scheme command to perform local or remote
authentication of username and password. The type of the authentication
depends on your configuration. For detailed information, see “AAA and RADIUS
Operation”
Perform username and password authentication when a user logs in through the
VTY 0 user interface and set the username and password to zbr and 3Com
respectively:
[SW7750-ui-vty0]authentication-mode scheme
[SW7750-ui-vty0]quit
[SW7750]local-user zbr
[SW7750-luser-zbr]service-type telnet
3Authorize users to use the command lines
The authentication-mode scheme command-authorization command indicates
that you must be authorized to use the command lines on the TACACS
