NE40/NE80忘记super密码的解决方法

NE40/NE80忘记super密码的解决方案

问题描述：

如果设备配置了super密码，并且包括console口在内的所有登录方式都被默认指定为level 0，那么在忘记super密码时，就无法进入配置视图，对设备进行维护。

本指导参考版本NE40/NE80 VRP3.10-0423。

解决方案：

当忘记super密码时，可以通过重启设备，进入bootrom菜单，然后按[ctrl] + z，进入隐含bootrom菜单，选择“Disable Config Password”后重新启动系统。这样用console用户登录的时候，super命令就不需要输入密码了。当然登录设备后还需要重新设置密码。不然下次登录还需要通过bootrom的操作实现。

下面是一个例子：
