Quidway 6500系列以太网交换机忘记console口密码的解决方法

Quidway 6500系列以太网交换机忘记console口密码的解决方法

一、   组网：

无

二、   问题描述：

客户Quidway 6506R以太网交换机长期未通过console口登录，忘记了设置的console口登录口令导致无法登录交换机。

三、   过程分析：

在配置了telnet的情况下，我们可以通过telnet方式登录到设备里，修改或者重新设置console口的登录口令。

如果没有配置telnet或者telnet登录之后用户权限不够，则只能通过删除密码或者删除配置文件的方式恢复对设备的控制权。

四、   解决方法：

如果用户设置的console登录口令丢失，又不能通过telnet方式修改口令，可以使用下面两种解决方法：

1.  删除启动文件中用户的console密码。

在BOOTROM菜单下，按CTRL+P键后敲击ENTER，删除指定启动文件中用户的console密码（同时会删除其他的密码，具体请看下面步骤）
