1.1.4 Configuring a Banner
I. Introduction to banners
Banners are prompt information displayed by the system when users are connected to the device, perform login authentication, and start interactive configuration. The administrator can set corresponding banners as needed. At present, the system supports the following four kinds of welcome information.
z shell banner, also called session banner, displayed when a non TTY Modem user enters user view.
z incoming banner, also called user interface banner, displayed when a user interface is activated by a TTY Modem user.
z login banner, welcome information at login authentications, displayed when password and scheme authentications are configured.
z legal banner, also called authorization information. The system displays some copyright or authorization information, and then displays the legal banner before a user logs in, waiting for the user to confirm whether to continue the authentication or login. If entering Y or pressing the Enter key, the user enters the authentication or login process; if entering N, the user quits the authentication or login process. Y and N are case insensitive.

II. Configuring a banner
When you configure a banner, the system supports two input modes. One is to input all the banner information right after the command keywords. The start and end characters of the input text must be the same but are not part of the banner information. In this case, the input text, together with the command keywords, cannot exceed 510 characters. The other is to input all the banner information in multiple lines by pressing the Enter key. In this case, up to 2000 characters can be input. The latter input mode can be achieved in the following three ways:
z Press the Enter key directly after the command keywords, and end the setting with the % character. The Enter and % characters are not part of the banner information.
z Input a character after the command keywords at the first line, and then press the Enter key. End the setting with the character input at the first line. The character at the first line and the end character are not part of the banner information.
z Input multiple characters after the command keywords at the first line (with the first and last characters being different), then press the Enter key. End the setting with the first character at the first line. The first character at the first line and the end character are not part of the banner information. Follow these steps to configure a banner:
To do… Use the command… Remarks Enter system view system-view — Configure the banner to be displayed at login (TTY header incoming text Optional Modem login) Configure the authorization information header legal text Optional before login Configure the banner to be displayed at login header login text Optional authentication Configure the banner to be displayed when a user header shell text Optional enters user view (Non-TTY Modem login)

Note: These hotkeys are defined by the system. When you interact with the device from terminal software, these keys may be defined to perform other operations. If so, the definition of the terminal software will dominate.
1.1.6 Configuring User Levels and Command Levels
All the commands are defaulted to different views and categorized into four levels: visit, monitor, system, and manage, identified respectively by 0 through 3. If you want to acquire a higher privilege, you must switch to a higher user level, and it requires password to do so for AUX and VTY user interfaces for the security’s sake. The following table describes the default level of the commands.
Table 1-2 Default command levels
Level Privilege Command 0 Visit ping, tracert, telnet 1 Monitor refresh, reset, send
1-5 Operation Manual – Basic System Configuration H3C S9500 Series Routing Switches Chapter 1 Basic Configurations
Level Privilege Command All configuration 2 System commands except for those at manage level FTP, TFTP, XMODEM, 3 Manage and file system operation commands
Follow these steps to configure user level and command level:
To do… Use the command… Remarks Switch the user level super [ level ] Optional
Enter system view system-view — Optional Configure the password super password [ level for switching the user user-level ] { simple | By default, no password is level cipher } password needed for switching the user level.
command-privilege Configure the command level level view view Optional level in system view command
Note: The commands available depend on your user level when you log onto a device. For example, if your user level is 3 and the command level of VTY 0 interface is 1, you can use commands below level 3 (inclusive).
Caution:
z When you configure the password for switching user level with the super password command, the user level is defaulted to 3 if no user level is specified.
z You can switch to a lower user level unconditionally. To switch to a higher user level, however, you need to enter the password needed (The password can be set with the super password command.). If the entered password is incorrect or no password is configured, the switch fails. Therefore, before switching to a higher user level, you should configure the password needed.
z You are recommended to use the default user level; otherwise the change of user level may bring inconvenience to your maintenance and operation.

1.1.7 Displaying and Maintaining Basic Configurations
To do… Use the command… Remarks Display information on display version system version Display information on the display clock system clock Display information on display users [ all ] terminal users Display the configuration display saved-configuration files saved in the device [ by-linenum ] storage medium.
display current-configuration [ interface [ interface-type [ interface-number ] ] | Display the current configuration [ configuration ] | configurations [ by-linenum ] | [ | { begin | exclude | include } Available in any regular-expression ] ] * view display debugging [ interface Display debugging interface-type interface-number ] information [ module-name ] Display the valid configuration under display this [ by-linenum ] current view Display clipboard display clipboard information Display and save statistics of each module’s display diagnostic-information running status Display the usage of the display memory current system memory
During daily maintenance or when the system is operating abnormally, you need to view each module’s running status to find the problem. Therefore, you are required to execute the corresponding display commands one by one. To collect more information one time, you can execute the display diagnostic-information command in any view to display statistics of each module’s running status. Use the display diagnostic-information command to collect at one time the information displayed by each of the following commands:
z display clock
z display version
z display device
z display current-configuration
1-7 Operation Manual – Basic System Configuration H3C S9500 Series Routing Switches Chapter 1 Basic Configurations
z display saved-configuration
z display interface
z display controller
z display fib
z display ip interface
z display ip statistics
z display memory
z display logbuffer
z display history all
Note:
z For the detailed description of the display users command, refer to User Interface Commands in the System Volume.
z The display commands discussed above are for the global configuration. Refer to the corresponding section for the display command for specific protocol and interface.
z If no configuration file is enabled when the device is started, no information is displayed by the display saved-configuration command; otherwise, the information of the configuration file is displayed. For the detailed information of the display saved-configuration command, refer to File System Management Commands in the System Volume.
z You are recommended to execute the display diagnostic-information command for at least two consecutive times, so that you can compare the differences between output running information to locate the fault. However, you should use this command only when necessary because execution of the command will continuously print lots of information, affecting the system operation.
