如果是采用simple方式配置口令则可以直接显示出密码。

如果是采用cipher方式配置口令,按照以下方法处理:

1)将查看到的配置文件复制保存成一个文本文件。

2)修改该文件中对应帐号的密码“password cipher ;)<01%^&;YGQ=^Q`MAF4<1!!”为类似“password simple aaa”的口令

3)将修改过的脚本,复制粘贴到当前路由器中

4disp cur确认当前配置和以前的配置一致后,save配置后重新启动系统

5)重启后,就可以通过修改过的帐号口令登录系统

 

【提示】

1、请注意路由器的配置脚本和口令的备份保存。以免带来不必要的麻烦!
