Resetting or Removing Configuration with "no"

It is possible to remove specific configuration items or reset them to their default values. In general, almost each configuration command has a corresponding no form. The ‘no’ form is syntactically similar (but not necessarily identical) to the configuration command, but either resets the parameters to defaults for the configurable item being addressed or removes the item altogether. In many cases, ‘’no’’ can be read as no(t) different from default settings.
