拓扑图
需求
如果把PC2的网线拔掉，再重新插回去，交换机会重新STP的收敛，会有30S——50S的转发延迟，交换机会检测接口会不会有环路，这个时候PC2是不能正常访问的
PC1——ping PC2

注意：
交换机的接口由down，到转发状态大概经过30S
down——>listening——>learning——>forwarding
解决办法
把连接PC的接口配置为边缘端口
SW1——把连接PC的接口配置边缘端口
[Huawei]int g0/0/3 //进入接口
[Huawei-GigabitEthernet0/0/3]stp edged-port enable //开启边缘端口
[Huawei-GigabitEthernet0/0/3]quit //退出
SW2——把连接PC的接口配置成静默接口
[Huawei]int g0/0/3 //进入接口
[Huawei-GigabitEthernet0/0/3]stp edged-port enable //开启边缘端口
[Huawei-GigabitEthernet0/0/3]quit //退出
[Huawei]
测试
把PC2的网线拔掉，再重新插回去，看数据是否可以直接转发

交换机连接PC的接口会直接转发数据，不会再STP收敛检测环路
