The function depends on the type of device. On devices with USB port this action imports the specified config from an inserted memory stick. On a micro switch running from internal memory this imports the specified config from a DOS formatted SD card. On all other switch versions this action will do nothing. When applicable this action imports the specified app installation file. If the app file name already exists the file is overwritten. Any already running version of the app is not affected. To actually install the imported app use the install command. Syntax: import_from_media = app_file
