拓扑图如下：
方法1（使用全局配置开启边缘端口，再启动BPDU保护，不过后面要关闭g 0/0/1和g 0/0/2的边缘端口）
[Huawei]stp edged-port default //开启交换机上的边缘端口，作用域为所有接口
[Huawei]stp bpdu-protection //实施BPDU保护，对边缘端口生效
//以下出现了问题，g0/0/1 和g 0/0/2关闭了，因为上面两条配置都是全局配置的，g0/0/1 和g 0/0/2不应该开启边缘端口的，当它们启动BPDU保护时，本来它们就会收到BPDU，因而被关闭了

解决方法（关闭两个接口的边缘端口）：
[Huawei-GigabitEthernet0/0/1]stp edged-port disable //关闭端口1的边缘端口
[Huawei-GigabitEthernet0/0/1]undo shutdown //重新开启端口1
[Huawei-GigabitEthernet0/0/2]stp edged-port disable
[Huawei-GigabitEthernet0/0/2]undo shutdown
方法2（对g 0/0/3和g 0/0/4接口单独开启边缘端口，再启动BPDU保护）
[Huawei]int g0/0/3
[Huawei-GigabitEthernet0/0/3]stp edged-port enable
[Huawei-GigabitEthernet0/0/3]int g0/0/4
[Huawei-GigabitEthernet0/0/4]stp edged-port enable
[Huawei-GigabitEthernet0/0/4]quit
[Huawei]stp bpdu-protection
