1.1.1 authentication-mode
Syntax
authentication-mode { password | scheme | none }
View
User interface view
Parameter
password: Perform local password authentication.
scheme: Perform local or remote authentication of username and password.
none: Perform no authentication.
Description
Using authentication-mode command, you can configure the authentication method
for login user.
This command with the password parameter indicates to perform local password
authentication, that is, you need to configure a login password using the set
authentication pass word { cipher | simple } password command.
This command with the scheme parameter indicates to perform authentication of local
or remote username and password. The type of the authentication depends on your
configuration. For detailed information, see “Security” section.
By default, users logging in via the Console port do not need to pass any terminal
authentication, whereas the password is required for authenticating the Modem and
Telnet users when they log in.
Example
# Configure local password authentication.
[Quidway-ui-aux0] authentication-mode password
1.1.2 auto-execute command
Syntax

undo auto-execute command
View
User interface view
Parameter
text: Specifies the command to be run automatically.
Description
Using auto-execute command command, you can configure to automatically run a
specified command. When a user logs in, the command configured will be executed
automatically. Using undo auto-execute command command, you can configure not
to run the command automatically.
This command is usually used to configure the telnet command on the terminal, which
will connect the user to a designated device automatically .
By default, auto run is disabled.
Caution:
z If you execute this command, the user-interface can no longer be used to perform
routine configurations on the local system. Therefore use caution when using this
command.
z Ensure that you will be able to log into the system in some other way to cancel the
configuration, before you configure the auto-execute command command and
save the configuration.
Example
# Configure to automatically telnet 10.110.100.1 after the user logs in via VTY 0.
[Quidway-ui-vty0] auto-execute command telnet 10.110.100.1

command, you can restore the default command priority.
The command levels include visit, monitoring, system, and management, which are
identified as 0 through 3 respectively. The network administrator can customize the
command levels as needed.
When users log into the switch, the commands they can use depend jointly on the user
level settings and the command level settings on the user interface. If the two types of
settings differ,
z For the users using AAA/RADIUS authentication, the commands they can use are
determined by the user level settings. For example, if a use is set to level 3 and the
command level on the VTY 0 user interface is level 1, he or she can only use the
commands of level 3 or lower when logging into the switch from the VTY 0 user
interface.
z For the users using RSA public key authentication, the commands they can use
are determined by the command level settings on the user interface.
By default, ping, tracert, and telnet are at visit level (0); display and debugging are at
monitoring level (1); all configuration commands are at system level (2); and FTP,
XMODEM, TFTP and commands for file system operations are at management level
(3).

When the users log in the switch, if a connection is activated, the login header will be
displayed. After the user successfully logs in the switch, the shell header will be
displayed.
Note that if you press <Enter> after typing any of the three keywords shell, login and
incoming in the command, then what you type after the word header is the contents of
the login information, instead of identifying header type.
You can judge whether the initial character can be used as the header contents this
way:
1) If there is only one character in the first line and it is used as the identifier, this
initial character pairs with the ending character and is not the header contents.
2) If there are many characters in the first line but the initial and ending characters
are different, this initial character pairs with the ending character and is the header
contents.
3) There are many characters in the first line and the initial character is identical with
the ending character, this initial character is not the header contents.
Example
# Configure the header of setting up a session.
Mode 1: Input in one line
[Quidway] header shell %SHELL: Hello! Welcome% (The starting and ending
characters must be the same, and press the <Enter> key to finish a line)
When you log on the switch again, the terminal displays the configured session
establishment title.
[Quidway] quit
<Quidway> quit
Please press ENTER
SHELL: Hello! Welcome (The initial character “%” is not the header contents)
<Quidway>
Mode 2: Input in several lines
[Quidway] header shell % SHELL: (After you pressing the <Enter> key, the system
prompts the following message:)
Input banner text, and quit with the character '%'.
Go on inputting the rest text and end your input with the first letter:
Hello! Welcome % (Press the <Enter> key)
[Quidway]
When you log on the switch again, the terminal displays the configured session
establishment title.

use after logon. Using undo service-type command, you can restore the d efault level
of command a user can use after logon.
Commands are classified into four levels, namely visit level, monitoring level, system
level and management level. They are introduced as follows:
z Visit level: Commands of this level involve command of network diagnosis tool
(such as ping and tracert), command of switch between different language
environments of user interface (language-mode), and telnet command etc. The
operation of saving configuration file is not allowed on this level of commands.
z Monitoring level: Commands of this level, including the display command and the
debugging command, are used for system maintenance, service fault diagnosis,
etc. The operation of saving the configuration file is not allowed on this level of
commands.
z System level: Service configuration commands, including routing command and
commands on each network layer, are used to provide direct network service to
the user.
z Management level: These are commands that influence the basic operation of the
system and system support module, which plays a supporting role on service.

# Quit the system and logs on with username “zbr” again. Now only the commands at
level 0 are listed on the terminal.
