华为交换机无论如何保存重启后，配置都丢失？

配置了很多遍交换机，save 保存后，重启。配置都丢失！？

那么。 重启交换机设备，初始化，刚读取配置文件时，按住CTRL+B，进BOOT ROM模式，


 BOOT  MENU


1. Download application file to flash
2. Select application file to boot
3. Display all files in flash
4. Delete file from flash
5. Modify bootrom password
6. Enter bootrom upgrade menu
7. Skip current configuration file
8. Set bootrom password recovery
9. Set switch startup mode
0. Reboot


Enter your choice(0-9): 7
The current setting is running configuration file when reboot.
Are you sure to skip current configuration file when reboot? Yes or No(Y/N) N

在重启设备时候，选7，Y/N，选N 就OK了。。。
