Extract flash:/vrptest.zip to flash:/vrpcfg.bat?[Y/N]:y
100%  complete
%Decompressed file flash:/vrptest.zip flash:/vrpcfg.bat.
3.执⾏execute命令，运⾏批处理⽂件vrpcfg.bat，在该配置的基础上可以删除原来配置的Console密码。
<Quidway>system-view
Enter system view, return user view with Ctrl+Z.
[Quidway]execute vrpcfg.bat  //通过execute命令把bat的⽂件导⼊到系统的现有配置⽂件。
[GT_3F]
[GT_3F]

接下来会覆盖配置，要等⼀段时间，滚动完了就覆盖完了。
<GT_3F>system-view
Enter system view, return user view with Ctrl+Z.
[GT_3F]user-interface console 0
[GT_3F-ui-console0]undo authentication-mode    //将原有配置的console串⼝密码删除
[GT_3F-ui-console0]undo authentication-mode    //将原有配置的console串⼝密码删除[GT_3F-ui-console0]quit
[GT_3F]quit
4.最后保存配置，重启恢复⽆console密码的原配置。
<GT_3F>save    //保存删除密码后的配置
The current configuration will be written to the device.
Are you sure to continue?[Y/N]y
Now saving the current configuration to the slot 0 .

<GT_3F>reboot            //重启，console密码被删除，同时原有的业务配置不丢失Info: The system is now comparing the configuration, please wait.
System will reboot! Continue?[Y/N]:y
根因
由于遗忘console⼝密码，⽆法登录设备
解决⽅案
通过修改配置⽂件中的配置，讲console⼝的认证模式删除或者不适⽤认证，即可
