软件方面最好在经常调试的笔记本上安装windosxp或windows2003server,安装好超级终端.另外在如果你的笔记本上只有linux系统那么就需要minicom.(Linux下图解minicom安装http://chenguang.blog.51cto.com/350944/937428)
如果你的机器没有超级终端,那么可采用SecureCRT这款软件也可以凑或用,不过笔者觉得最好还是超级终端(因为他反应迅速).以下几幅图就是操作步骤：

好啦，经过上面简单的几个步骤，忘记的密码就清除啦，当然也适用于其他型号的设备。
补充：如果是路由器，在开机过程中按Ctrl+Break进入rommon模式，修改配置寄存器为0x2142，之后reset重启。开机后，把Startup-config复制到running-config，去掉密码后把config-register改回0x2102，保存。
