or the file will be inaccessible.

3.1.5 Configuring the undo Command to Automatically Match the
Higher-Level View
After performing this configuration, if a user runs the undo command when the undo command
is not registered in the current view, the system automatically switches to the view one level up
from the current view and searches for this command there. If the command is found, the
undo command takes effect. If the undo command does not exist in this view, the system
progressively searches higher-level views for the command until reaching the system view. If
not found in the higher-level view, the undo command will not be executed.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
matched upper-view
The undo command is configured to automatically search higher-level views if run in a view
where it is not registered.
By default, the undo command does not automatically search higher-level views.
NOTE
l The matched upper-view command is valid for current login users who run this command.
l Configuring the undo command to automatically match the upper level view is recommended only if
necessary.
