一、華為交換機設置console口密碼：

<Amet-NJ-SW-01>system-view//進系統視圖

[Amet-NJ-SW-01]user-interface console 0//進入console 0口（就一個console口，默認為0口）

[Amet-NJ-SW-01-ui-console0]authentication-mode password//啟用密碼認證

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

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