The auto-execute command command is supported on all types of user interfaces except the Console port and the AUX port functioning as 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.

Caution:

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 telnet 10.10.10.1 command after a user logs on from the VTY 0 interface.

<Sysname> system-view

[Sysname] user-interface vty 0

[Sysname-ui-vty0] auto-execute command telnet 10.10.10.1

Description

Use the service-type telnet command to configure the command level available to a user logging in.

Use the undo service-type telnet command to restore the default.

There are four command levels: visit, monitor, system, and manage.

l Visit: involves commands for network diagnosis, such as ping and tracert, and command telnet. Saving the configuration file is not allowed at this level.

l Monitor: includes the display and debugging commands for system maintenance and service fault diagnosis. Saving the configuration file is not allowed at this level.

l System: provides service configuration commands including routing and commands at each level of the network for providing services.

l Manage: Commands at this level concern file system, file transfer protocol (FTP), trivial file transfer protocol (TFTP), downloading using XModem, user management, and level setting, which influence the basic operation of the system and the system support modules for service support.

View

User interface view

Default Level

3: Manage level

Parameters

simple: Plain text password.

cipher: Cipher 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.

By default, Telnet users must provide passwords at login, that is, the authentication-mode password command applies. If no password is configured, the following information appears:

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

1.1.32 terminal type

Syntax

terminal type { ansi | vt100 }

undo terminal type

View

User interface view

Default Level

2: System level

Parameters

ansi: Specifies the terminal display type as ANSI.

vt100: Specifies the terminal display type as VT100.

Description

Use the terminal type command to configure the type of terminal display.

Use the undo terminal type command to restore the default.

By default, the terminal display type is ANSI.

Note that the system supports two types of terminal display: ANSI and VT100. If the terminal display of the device and the client (for example, hyper terminal or Telnet terminal) is inconsistent or is set to ANSI, and if the total number of the characters of the currently using command line exceeds 80, anomalies such as cursor corruption or abnormal display of the terminal display may occur on the client. Therefore, you are recommended to set the display type of both the device and the client to VT100.

Examples

# Set the terminal display type to VT100.

[Sysname] user-interface vty 0

[Sysname-ui-vty0] terminal type vt100
