实验环境检查
查看Opendaylight控制器
登陆Opendaylight控制器，在查看控制器主机的6633端口监听状态
root@guest-virtual-machine:/home/guest# netstat -an|grep 6633
关闭防火墙
sudo ufw disable访问WEB页面
在OVS主机(Miniet主机)中创建拓扑结构，并测试连通性
sudo mn --topo=single,3 --controller=remote,ip=192.168.123.10,port=6633 --switch ovsk,protocols=OpenFlow13
在控制器页面查看到的拓扑图
使用postman查看交换机id信息，交换机id为1
