4、選擇8-Rename file in CFCard，把9300默認配置文件vrpcfg.zip改為其他名稱，例如為vrptest；

5、重啟后進入較交換機，此時交換機為出廠的默認配置；

6、把改名后的文件vrptest解壓縮為vrpcfg.bat

unzip vrptest vrpcfg.bat

7、執(zhí)行execute命令，把原有的配置調(diào)用出來，在此基礎(chǔ)上可把console的密碼去掉。

sys                                                                   

Enter system view, return user view with Ctrl+Z.                               

[Quidway]exec                                                                  

[Quidway]execute vrpcfg.bat 

[Quidway]user-inter console 0                                                  

[Quidway-ui-console0]undo auth

8、保存配置為vrpcfg.zip   

save                                           

The current configuration will be written to the device. Continue? [Y/N]:y     

Info: Please input the file name(*.cfg,*.zip)[vrpcfg.zip]:

hether to save the configuration to the device.    vrpcfg.zip    -----這里要輸入正確的9300默認配置文件名稱 vrpcfg.zip 

9、重啟交換機后，console密碼被刪除，同時原有的業(yè)務(wù)配置不丟失。
