CAUTION
l 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.
l If file is specified, save the file containing the header in the root directory of the default
storage medium. If the file is saved in another directory, specify the full path in the file name;
otherwise, the configuration fails.
l If a user logs in to the router by using SSH1.X, the login header is not displayed during login,
but the shell header is displayed after login.
l If a user logs in to the router by using SSH2.0, both login and shell headers are displayed.

3.1.5 Configuring the Undo Command to Match in the Previous
View Automatically
You can run the undo command in the current view and thus the system automatically matches
the previous view.
Context
If the user allows the undo command to automatically match the previous view and the user
runs the undo command that is not registered in the current view, the system searches the
undo command in the previous view.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
matched upper-view
The undo command is configured to match the upper level view.
By default, the undo command does not match the previous view automatically.
NOTE
l The matched upper-view command is valid for current login users who run this command.
l It is not recommended that you configure the undo command to automatically match the upper level
view, unless necessary.
