Using the no version or reset version removes the all keyword and restores default privilege levels.
If the privilege setting of the mode or command for which you are restoring default privilege levels takes precedence over any ineffective privilege settings, those settings will automatically take effect according to the order of precedence (see Using the Order of Precedence ).
The difference between the no version and the reset version is that the reset version removes the configuration from the show configuration output. This is useful when you want to remove a configuration that has been overridden and rendered ineffective by a privilege level that takes precedence.
