Executing this command with the password keyword specifies to perform local password authentication, that is, you need to configure a login password using the set authentication password { cipher | simple } password command.

Executing this command with the scheme keyword specifies to perform AAA using the AAA scheme specified for the ISP domain. Whether local or remote scheme authentication is adopted depends on the configuration described in the AAA/RADIUS/HWTACACS part of this manual.

Executing this command with the command-authorization keyword specifies to perform command line authorization. An input command is executed only after it passes authorization. The related authorization mode depends on the AAA scheme used by the ISP domain. If multiple AAA schemes are configured for an ISP domain, the AAA scheme used at user login is used first.

By default, terminal authentication is not required for local users log in via the console port. However, password authentication is required for local users and remote Modem users to log in via the AUX port, and for Telnet users and VTY users to log in through Ethernet port.

Note: If the console port is configured for local password authentication, the user can directly log in to the system even without a password configured; if other user interfaces, such as the AUX port and VTY interface, are configured for local password authentication, users cannot log in to the system without a password.

1.1.10 header

Syntax

header [ shell | incoming | login ] text

undo header [ shell | incoming | login ]

View

System view

Parameters

login: Login information in case of authentication. It is displayed before the user is prompted to enter user name and password.

shell: User conversation established header, the information output after user conversation has been established. If authentication is required, it is prompted after the user passes authentication.

incoming: Login header, the information output after a Modem user logs in. If authentication is required, it is prompted after the user passes authentication. In this case, no shell information is output.

text: Specifies the title text. If you do not choose any keyword in the command, the system displays the login information by default. The system supports two types of input modes: one is to input all the text in one line, and altogether 256 characters (including carriage returns), including command key word, can be input; the other is to input all the text in several lines using the <Enter> key, and altogether 2048 characters, excluding command key word, can be input. The text starts and ends with the first character. After inputting the end character, press the <Enter> key to exit the interact process.

Description

Use the header command to configure to display header when user login.

Use the undo header command to configure not to display the header.

When the user logs in to the switch, if a connection is activated, the login header will be displayed. After the user successfully logs in to 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:

l Input texts in multiple lines. You need to enter only one character in the first line. The character and the last character of the string entered serve as the identifiers of the header content and must be the same. For example,

<H3C> system-view

System View: return to User View with Ctrl+Z.

[H3C] header shell 0

Input banner text, and quit with the character '0'.

Welcome !0

(The starting and ending characters must be the same, and press the <Enter> key to finish a line)

When you log in to the switch again, the preset session establishment header “welcome!” is displayed on the terminal screen.

The initial character 0 is not header contents.

For another example,

<H3C> system-view

System View: return to User View with Ctrl+Z.

[H3C] header shell 0

Input banner text, and quit with the character '0'.

Hello,

Welcome!0

(The starting and ending characters must be the same, and press the <Enter> key to finish a line)

When you log in to the switch again, the preset session establishment header “Hello, welcome!” is displayed on the terminal screen. The initial character 0 is not header content.

l You can also input the header content in a single line. In this case, the beginning and the end character serve as the identifiers and must be the same. For example,

<H3C> system-view

System View: return to User View with Ctrl+Z.

[H3C] header shell 0welcome,my friend!0

(The starting and ending characters must be the same. Press the <Enter> key to finish a line)

When you log in to the switch again, the preset session establishment header “welcome, my friend!” appears on the terminal screen. The beginning and the end characters, that is, character 0, are not displayed.

l Finally, you can input the header content in multiple lines, with multiple characters contained in the first line. The initial character is different from the ending one and the initial character pairs with the ending one. The initial character is the text contents, for example,

<H3C> system-view

System View: return to User View with Ctrl+Z.

[H3C] header shell hello

Input banner text, and quit with the character 'h'.

my friend !

(The starting and ending characters must be the same, and press the <Enter> key to finish a line)

When you log in to the switch again, the preset session establishment header “hello, my friend!” is displayed on the terminal screen. The initial character “h” is the header contents.

Examples

# Set the header for the switch.

Option 1: Input in one line

<H3C> system-view

System View: return to User View with Ctrl+Z.

[H3C] 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 in to the switch again, the terminal displays the header you set.

[H3C] quit

<H3C> quit

Please press ENTER

SHELL: Hello! Welcome

(The character “%” is not displayed.)

<H3C>

Option 2: Input in multiple lines

[H3C] header shell % SHELL:

(After you press 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)

[H3C]

When you log in to the switch again, the following is displayed.

[H3C] quit

<H3C> quit

Please press ENTER

%SHELL:

(The character “%” is contained in the header.)

Hello! Welcome

<H3C>
