Usage Guidelines

Usage Scenario

The header command allows a header to be displayed on terminals after users log in.

When using this command, note the following points:

If a user logs in and is being authenticated, the login header is displayed on the terminal.
If the user successfully logs in, the shell header is displayed on the terminal.

Configuration Impact

After a header is configured, the header welcomes all login users.

Follow-up Procedure

The header text starts and ends with the same character. After a character is input and Enter is pressed, an interactive interface is displayed. You can input the required information ended with the first character. The system then exits from the interactive interface.

If you do not want to enter the interactive interface, use the same character at the beginning and end of the header and press Enter.

Precautions

The login header is displayed only after authentication is configured for users in advance.
A file must exist before the file parameter is configured. Otherwise, a message is displayed, indicating the file name cannot be obtained.
A header text contains a maximum of 220 characters, including the start and end characters.
If a user logs in to the FW by using SSH1.X, the login header is not displayed during login, but the shell header is displayed after login.
If a user logs in to the FW by using SSH2.0, both login and shell headers are displayed.

Example

# Configure a shell header.

<sysname> system-view
[sysname] header shell information %
The banner text supports 220 characters max, including the start and the end cha
racter.If you want to enter more than this, use banner file instead.Input banner
