activation-key
Syntax
activation-key character
undo activation-key
View
User interface view
Default Level
3: Manage level
Parameters
character: Shortcut key for starting terminal sessions, a single character (or its corresponding ASCII code value in the range 0 to 127) or a string of 1 to 3 characters. But in fact, only the first character functions as the shortcut key. For example, if you input an ASCII code value 97, the system will use its corresponding character a as the shortcut key; if you input the string b@c, the system will use the first letter b as the shortcut key.
Description
Use the activation-key command to define a shortcut key for starting a terminal session.
Use the undo activation-key command to restore the default.
By default, pressing the Enter key starts the terminal sessions. However, if you define a new shortcut key using the activation-key command, the Enter key no longer functions. You can use the display current-configuration command to display the shortcut key you have defined.
The display current-configuration command is not supported on the VTY user interface.
Examples
# Use letter s as the shortcut key for starting terminal sessions on the console port.
<Sysname> system-view
[Sysname] user-interface console 0
[Sysname-ui-console0] activation-key s
To verify the configuration, do the following:
# Exit the terminal session on the console port.
[Sysname-ui-console0] return
<Sysname> quit

auto-execute command
Syntax
auto-execute command command
undo auto-execute command
View
User interface view
Default Level
3: Manage level
Parameters
command: Command to be automatically executed.
Description
Use the auto-execute command command to specify a command to be executed automatically.
Use the undo auto-execute command command to disable this feature.
By default, command auto-execution is disabled.
The auto-execute command command is supported on all types of user interfaces except the console port.
Once a command is configured using the auto-execute command command, the system automatically executes the command when a user logs on from the interface where the command is configured. After the command is completed, the connection breaks automatically.
A good example is configuring the auto-execute command telnet command to let users telnet to the specified host automatically.
The auto-execute command command may disable you from configuring the system through the terminal line to which the command is applied. Therefore, before configuring the command and saving the configuration (using the save command), make sure that you can access the system by other means to remove the configuration in case a problem occurs.
Examples
# Automatically execute the display brief interface loopback command after a user logs on from the VTY 0 interface.
<Sysname> system-view
[Sysname] user-interface vty 0 4
[Sysname-ui-vty0-4] auto-execute command display brief interface loopback
% This action will lead to configuration failure through ui-vty0-4. Are you sure? [Y/N]:y

escape-key
Syntax
escape-key { default | character }
undo escape-key
View
User interface view
Default Level
3: Manage level
Parameters
character: Specifies the shortcut key for aborting a task, a single character (or its corresponding ASCII code value in the range 0 to 127) or a string of 1 to 3 characters. But in fact, only the first character functions as the shortcut key. For example, if you enter an ASCII code value 113, the system will use its corresponding character q as the shortcut key; if you input the string q@c, the system will use the first letter q as the shortcut key.
default: Restores the default escape key combination Ctrl+C.
Description
Use the escape-key command to define a shortcut key for terminating tasks.
Use the undo escape-key command to disable the shortcut key for aborting tasks.
By default, you can use Ctrl+C to terminate a task.
After defining a new shortcut key using the escape-key command, the new shortcut key will function to terminate a task. You can use the display current-configuration command to display the shortcut key you have defined.
Note that if you set the character argument in a user interface of a device, when you use the user interface to log in to the device and then telnet to another device through the device you have logged in, the character argument can be used as a control character to terminate a task only, rather than input as a common character. For example, if you specify character as e in VTY 0 user interface of Device A, when you log in to the Device A using VTY 0 on PC (Hyper Terminal), you can input e as a common character on PC, and you can also use e to terminate the task running on Device A. If you telnet to Device B through Device A, however, you can only use e to terminate the task running on Device B, rather than input e as a common character. Therefore, you are recommended to specify character as a key combination.
Examples
# Define <a> as the escape key.
<Sysname> system-view
[Sysname] user-interface console 0
[Sysname-ui-console0] escape-key a
To verify the configuration, do the following:
# Use the ping command to check the reachability of the device with the IP address of 192.168.1.49 and use the -c argument to specify the number of the ICMP echo packets to be sent as 20.
<Sysname> ping -c 20 192.168.1.49

screen-length
Syntax
screen-length screen-length
undo screen-length
View
User interface view
Default Level
2: System level
Parameters
screen-length: Number of lines displayed on the next screen, in the range 0 to 512, with zero meaning to display all information at one time, that is, to disable multiple-screen output.
Description
Use the screen-length command to set the number of lines displayed on the next screen.
Use the undo screen-length command to restore the default, or 24 lines.
Multiple-screen output is supported on the device. If you press the Space key when information display pauses, the system continues to display information of the next screen page. This command sets the number of lines displayed on the next screen, the displayed number of lines on the terminal, however, is decided by the specifications of the terminal. For example, you set the value of screen-length to 40, but the terminal can only display 24 lines. In this case, if you press the Space key when the device outputs 1 to 40 lines of information to the terminal, the current screen displays only the information from line 18 to 40. To view the first 17 lines of information, you need to press Page Up or Page Down.
The command sets the number of lines displayed on the next screen, and you can use the screen-length disable command to disable multiple-screen output of the current user interface. For more information about the screen-length disable command, see CLI in the Fundamentals Command Reference.

set authentication password
Syntax
set authentication password { cipher | simple } password
undo set authentication password
View
User interface view
Default Level
3: Manage level
Parameters
cipher: Cipher text password.
simple: Plain text password.
password: A case sensitive string. If the password format is set to simple, the password argument must be in plain text. If it is set to cipher, password can be either in cipher text or in plain text depending on what has been input. A plain text password can be a string of no more than 16 consecutive characters, 1234567 for example. A cipher text password, or the encrypted version of the plain text password, comprises 24 characters, such as _(TT8F]Y\5SQ=^Q`MAF4<1!!.
Description
Use the set authentication password command to set a local authentication password.
Use the undo set authentication password command to remove the local authentication password.
No local authentication password is set by default.
l When setting a password, you should specify simple to save it in plain text in the configuration file, or specify cipher to save it in cipher text.
l Whether the password format is plain text or cipher text, you must type in plain text password at authentication.
l Plain text password easily gets cracked. Therefore, you are recommended to use cipher text password.
Related commands: authentication-mode.
Examples
# Set the local authentication password for the user interface console 0 to hello.
<Sysname> system-view
[Sysname] user-interface console 0
[Sysname-ui-console0] authentication-mode password
[Sysname-ui-console0] set authentication password cipher hello
After setting the password, you will be required to input the password next time you enter the system.
