1.2  如果不需要之前的配置信息的话

操作步骤：跳过启动文件后直接保存当前配置，再重启。

<H3C>save

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

Please input the file name(*.cfg)[flash:/startup.cfg]

(To leave the existing filename unchanged, press the enter key):（输入回车）

flash:/startup.cfg exists, overwrite? [Y/N]:y

Validating file. Please wait...

Configuration is saved to device successfully.

<H3C>reboot

Start to check configuration with next startup configuration file, please wait.........DONE!

Current configuration may be lost after the reboot, save current configuration? [Y/N]:y

This command will reboot the device. Continue? [Y/N]:y

如果需要之前配置需要将之前的配置文件通过FTP或者TFTP导出，修改console密码后导入设备重启。
