l If you specify the password keyword to authenticate users using the local password, remember to set the local password using the set authentication password { cipher | simple } password command at the same time.

l If you specify the scheme keyword to authenticate users locally or remotely using usernames and passwords, the actual authentication mode, that is, local or remote, depends on other related AAA scheme configuration of the domain.

l If this command is executed with the command-authorization keyword specified, authorization is performed on the TACACS server whenever you attempt to execute a command, and the command can be executed only when you pass the authorization. Normally, a TACACS server contains a list of the commands available to different users.

If you specify to perform local authentication when a user logs in through the Console port, a user can log in to the switching engine with the password not configured. But for a VTY user interface, a password is needed for a user to log in to the switching engine through it under the same circumstance.

By default, users logging in through the Console port are not authenticated, whereas modem users and Telnet users are authenticated.

For a VTY user interface, to specify the none keyword or password keyword for login users, make sure that SSH is not enabled in the user interface. Otherwise, the configuration fails. Refer to section protocol inbound for related configuration.

To improve security and prevent attacks to the unused Sockets, TCP 23 and TCP 22, ports for Telnet and SSH services respectively, will be enabled or disabled after corresponding configurations.

l If the authentication mode is none, TCP 23 will be enabled, and TCP 22 will be disabled.

l If the authentication mode is password, and the corresponding password has been set, TCP 23 will be enabled, and TCP 22 will be disabled.

l If the authentication mode is scheme, there are three scenarios: when the supported protocol is specified as telnet, TCP 23 will be enabled; when the supported protocol is specified as SSH, TCP 22 will be enabled; when the supported protocol is specified as all, both the TCP 23 and TCP 22 port will be enabled.

header

Syntax

header [ incoming | legal | login | shell ] text

undo header { incoming | legal | login | shell }

View

System view

Parameters

incoming: Sets the login banner for users that log in through modems. If you specify to authenticate login users, the banner appears after a user passes the authentication. (The session does not appear in this case.) The device does no support Modem login.

legal: Sets the authorization banner, which is displayed when a user enters user view.

login: Sets the login banner.

shell: Sets the banner displayed when a non Modem login user enters user view.

text: Banner to be displayed. If no keyword is specified, this argument is the login banner. You can provide this argument in two ways. One is to enter the banner in the same line as the command (A command line can accept up to 254 characters.) The other is to enter the banner in multiple lines (you can start a new line by pressing Enter,) where you can enter a banner that can contain up to 2000 characters (including the invisible characters such as carriage return). Note that the first character is the beginning character and the end character of the banner. After entering the end character, you can press Enter to exit the interaction.

Description

Use the header command to set the banners that are displayed when a user logs in to the switching engine. The login banner is displayed on the terminal when the connection is established. And the session banner is displayed on the terminal if a user successfully logs in.

Use the undo header command to disable displaying a specific banner or all banners.

By default, no banner is configured.

Note the following:

l If you specify any one of the four keywords without providing the text argument, the specified keyword will be regarded as the login information.

l The banner configured with the header incoming command is displayed after a modem user logs in successfully or after a modem user passes the authentication when authentication is required. In the latter case, the shell banner is not displayed.

l The banner configured with the header legal command is displayed when you enter the user interface. If password authentication is enabled or an authentication scheme is specified, this banner is displayed before login authentication.

l With password authentication enabled or an authentication scheme specified, the banner configured with the header login command is displayed after the banner configured with the header legal command and before login authentication.

l The banner configured with the header shell command is displayed after a non-modem user session is established.

You can specify the banner in the following three ways:

l Enter the banner in a single line. If there are multiple characters and the first character is the same as the last character, the first character does not act as part of the banner. The following gives an example of this way:

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

After you execute the above command and then log in again, “Welcome, my friend!” is displayed.

l Enter the banner in multiple lines. If you only type one character in the first line of a banner, the character and the last character do not act as part of the banner. The following gives an example of this way.

[device] header shell 0

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

Welcome!0

When you log in the next time, “Welcome!” is displayed as the banner. The beginning character and the end character (character 0) do not appear.

l Enter the banner in multiple lines. If you type multiple characters in the first line of a banner and the beginning and the end characters of the banner in this line are not the same, the beginning character is part of the banner. The following is an example.

[device] header shell hello

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

my friend!

When you log in the next time, hello and my friend! are displayed in two lines as the banner. The beginning character h appears in the banner.

Examples

# Set the session banner.

Option 1: Enter the banner in the same line as the command.

<device> system-view

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

[device] header shell %SHELL: Hello! Welcome%

When you log in the next time, the session banner appears on the terminal as the following:
