●普通权限的管理命令用于日常管理●高级权限的管理命令用于特殊任务，比如系统调优、测试、统计等。

这种命令如果使用不当可能毁坏数据，所以推荐别在高级权限模式长时间停留。

●Options类的命令●Flash启动命令在设备启动阶段可以获得普通权限的命令在命令行打问号可以获得提示，主要是为了磁盘管理、网络和系统管理、物理或者虚拟接口管理等。

下面是一系列普通权限的命令：Configuration类—黄色的是这一类命令tan> softwar命令用于从HTTP或HTTPS服务器下载DataONTAP软件镜像到filer,管理软件并安装或升级它们，一般是SETUP.EXE(NETAPP发布的)文件，软件下载后保存在根卷的/etc/software。
