1、通過BootWare選單恢復Console口登入認證密碼

2，重啟裝置按Ctrl+B進入BootWare主選單，選擇<6>，即以忽略系統當前配置的方式啟動，此時裝置不會刪除上次啟動時載入的配置檔案。

(1) 系統出現如下提示表明已經設定成功。

Flag Set Success.

(2) 當再次出現BootWare主選單時，選擇<1>，裝置開始啟動。

(3) 重啟裝置後，裝置的配置為空，使用者可以在系統檢視下配置回滾恢復原有配置，如下配置表示將當前配置回滾到配置檔案startup.cfg中的配置狀態。如果使用者不想恢復原有配置，請跳過此步驟。

<Sysname> system-view
[Sysname] configuration replace file flash:/startup.cfg
Current configuration will be lost, save current configuration? [Y/N]:n
Now replacing the current configuration. Please wait ...
Succeeded in replacing current configuration with the file flash:/startup.cfg.

(4) 在系統檢視下設定新的Console口的登入認證模式和密碼，例如：設定Console口驗證方式為密碼驗證，且以明文方式設定Console口的密碼為123456。

<Sysname> system-view
[Sysname] line console 0
[Sysname-line-console0] authentication-mode password
[Sysname-line-console0] set authentication password simple 123456

(5)儲存新配置。

[Sysname-line-console0] save
