1、通過BootWare菜單恢復Console口登錄認證密碼
2，重啟設備按Ctrl+B進入BootWare主菜單，選擇<6>，即以忽略系統當前配置的方式啟動，此時設備不會刪除上次啟動時加載的配置文件。

(1) 系統出現如下提示表明已經設置成功。
Flag Set Success.
(2) 當再次出現BootWare主菜單時，選擇<1>，設備開始啟動。
(3) 重啟設備后，設備的配置為空，用戶可以在系統視圖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文件startup.cfg中的配置狀態。如果用戶不想恢復原有配置，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) 在系統視圖下設置新的Console口的登錄認證模式和密碼，例如：設置Console口驗證方式為密碼驗證，且以明文方式設置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) 保存新配置。
[Sysname-line-console0] save
