在用户视图下执行reset saved-configuration，然后使用reboot命令重启路由器即可。
在配置reset saved-configuration命令后，重启设备时请选择不保存当前配置文件。
清除和重新配置的信息只能在设备重新启动后生效，当前配置不变。
依次输入命令：reset saved-configuration —>Y—>reboot—>N—>Y
<SW2>reset saved-configuration

四、清除交换机或路由器某个端口地配置命令
<huawei>system-view
[huawei]interface gigabitethernet 0/0/? (?:表示第几个端口)
[huawei-GigabitEthernet0/0/?]clear configuration interface gigabitethernet 0/0/?
清除该端口的配置后，该端口处于关闭状态，可以用以下命令重新开启。
[huawei-GigabitEthernet0/0/?]undo shutdown
