本实验的主要任务是练习通过Console电缆连接进行设备配置的方法。试验前请保证路由器(交换机)的所有配置已经清空。
在PC桌面上运行【开始】->【程序】->【附件】->【通信】->【超级终端】。填入一个任意名称,点击【确定】。
每秒位数为9600bps、8位数据位、1位停止位、无奇偶校验和无流量控制
用户视图的提示符为<系统名>
执行system-view命令进入系统视图。系统视图的提示符为[系统名]。执行quit命令可以从系统视图切换到用户视图。

默认配置文件名通常为startup.cfg,某些版本为config.cfg。

由于执行了save命令,保存配置与运行配置一致。

用more命令
使cd命令
用save、dir、delete、dir命令
虽然删除了该文件,但是在删除该文件前后,为什么CF卡的可用内存空间却没有变化呢。那是因为使用delete命令删除文件时,被删除的文件被保存在回收站中,仍会占用存储空间。如果用户经常使用该命令删除文件,则可能导致设备的存储空间不足。如果要彻底删除回收站中的某个废弃文件,必须在文件的原归属目录下执行reset recycle-bin命令,才可以将回收站中的废弃文件彻底删除,以回收存储空间。
dir /all命令显示内容包括隐藏文件、隐藏子文件夹以及回收站中的原属于该目录下的文件的信息,回收站里的文件会以方括号“[ ]”标出。文件myconfig.cfg应该仍然存在于CF卡的回收站中。
用reset recycle-bin命令清空回收站后,可发现文件列表中已经找不到myconfig.cfg文件,并且可用内存空间已经增加。
使用delete /unreserved命令删除一个文件,则该文件将被彻底删除,不能再恢复。其效果等同于执行delete命令之后,再在同一个目录下执行了resetrecycle-bin命令。

由于此时登录用户处于访问级别,所以只能看到并使用有限的几个命令。同时,超级终端上会有如下信息显示,表明源IP为192.168.0.10的设备远程登入到路由器上。
