如果有一台已经配置过的华为交换机想拿到一个新的网络环境中使用，那么存在的老配置对你的新网络已经没有任何的利用价值，那么手动清除相对较慢，不如我们利用恢复出厂设置的这个机制来完成。
<A>reset saved-configuration
Warning: The action will delete the saved configuration in the device.
The configuration will be erased to reconfigure. Continue? [Y/N]:Y
Warning: Now clearing the configuration in the device.
Info: Succeeded in clearing the configuration in the device.
<A>reboot

Warning: All the configuration will be saved to the configuration file for the n
ext startup:, Continue?[Y/N]:N
Info: If want to reboot with saving diagnostic information, input 'N' and then e
xecute 'reboot save diagnostic-information'.
System will reboot! Continue?[Y/N]:Y
这样重新启动过后，该交换机就恢复到了出厂设置，很简单吧，你学会了吗？？
