2. 將改名字后的文件vrptest解壓縮為vrpcfg.bat。
<Quidway>dir
Directory of flash:/
Idx Attr Size(Byte) Date Time FileName
0 -rw- 1,752 Oct 01 2008 01:07:03 private-data.txt

...

<Quidway>unzip vrptest.zip vrpcfg.bat //需要把vrptest.zip的文件解壓成bat的格式
Extract flash:/vrptest.zip to flash:/vrpcfg.bat?[Y/N]:y
100% complete
%Decompressed file flash:/vrptest.zip flash:/vrpcfg.bat.
3.執行execute命令，運行批處理文件vrpcfg.bat，在該配置的基礎上可以刪除原來配置的Console密碼。
<Quidway>system-view
Enter system view, return user view with Ctrl+Z.
[Quidway]execute vrpcfg.bat //通過execute命令把bat的文件導入到系統的現有配置文件。
[GT_3F]
[GT_3F]
Info: This operation may take a few seconds. Please wait for a moment...done.
接下來會覆蓋配置，要等一段時間，滾動完了就覆蓋完了。
<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 //將原有配置的console串口密碼刪除
[GT_3F-ui-console0]quit
[GT_3F]quit
4.最后保存配置，重啟恢復無console密碼的原配置。
<GT_3F>save //保存刪除密碼后的配置
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 .
Info: Save the configuration successfully.
<GT_3F>reboot //重啟，console密碼被刪除，同時原有的業務配置不丟失
Info: The system is now comparing the configuration, please wait.
System will reboot! Continue?[Y/N]:y
根因
由於遺忘console口密碼，無法登錄設備
解決方案
通過修改配置文件中的配置，講console口的認證模式刪除或者不適用認證，即可
