Description The router provides rich debugging functions for troubleshooting networks.
Enabling debugging generates a large amount of debugging information resulting in
decreased efficiency, especially when the debugging all command is executed.
An aftermath of doing so is system crash. For these reasons, you are not encouraged
to use the debugging all command. The undo debugging all command, on
the contrary, is helpful when you want to disable all debugging switches at a time.
