Setup guide

The history of system configuration changes is held until the next router shutdown. The invoked
commands can be 'undone' (in reverse order they have been invoked). The 'undone' commands may
be 'redone' (in reverse order they have been 'undone').
Command Description
/undo - undoes previous configuration changing command (except another '/undo' command)
/redo - undoes previous '/undo' command
/system history print - print a list of last configuration changes, specifying whether the action can
be undone or redone
Notes
Floating-undo actions are created within the current SAFE mode session. They are automatically
converted to undoable and redoable when SAFE mode terminated successfully, and are all undone
irreverively when SAFE mode terminated insuccessfully.
Undo command cannot undo commands past start of the SAFE mode.
Example
