Exit (command)

The exit command exits the current configuration mode. If the current configuration level isn't the top-most, then the configuration level is put back to the top-most level. If the configuration level is at the top-most level, then it exits the configuration mode and returns to operational mode. The exit command cannot be used if uncommitted changes exists in the configuration file. To exit with uncommitted changes, you either need to use the exit discard command or you need to commit   the changes before exiting. The exit command doesn't save the configuration, only the save command does. A warning will be given when exiting with unsaved changes. Using the exit command in operational mode will logout the session.
