一、華為交換機(jī)設(shè)置console口密碼：

<Amet-NJ-SW-01>system-view//進(jìn)系統(tǒng)視圖

[Amet-NJ-SW-01]user-interface console 0//進(jìn)入console 0口（就一個(gè)console口，默認(rèn)為0口）

[Amet-NJ-SW-01-ui-console0]authentication-mode password//啟用密碼認(rèn)證

[Amet-NJ-SW-01-ui-console0]set authentication password cipher Aa123456//設(shè)置終端登錄密碼

[Amet-NJ-SW-01-ui-console0]quit

Dec 24 2021 15:20:17 Amet-NJ-SW-01 DS/4/DATASYNC_CFGCHANGE:OID 1.3.6.1.4.1.2011.5.25.191.3.1 configurations have been changed.The current change number is 2,the change loop count is 0,and the maximum number of records is 4095.

[Amet-NJ-SW-01-ui-console0]quit

[Amet-NJ-SW-01]quit

<Amet-NJ-SW-01>

二、華為交換機(jī)恢復(fù)出廠配置

<Amet-NJ-SW-01>reset factory-configuration

Warning:The command will delete all the configurations and files

except the startup,patch,module,and license files

from the device.Continue?[Y/N]:y

Warning:The system will reboot after configurations and files are deleted.Continue?[Y/N]:y

Info:Start restoring factory configurations.Please wait....

Info:This operation will take several seconds.Please wait.....

三、華為交換機(jī)默認(rèn)登錄用戶名和密碼

Username:admin

Password:admin huawei.com

或者是Admin huawei.com

四、華為路由器破解密碼
