使用Postman下发流表实验环境检查查看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1http://192.168.123.10:8080/restconf/operational/network-topology:network-topology下发第一条流表PUThttp://192.168.123.10:8080/restconf/config/opendaylight-inventory:nodes/node/openflow:1/table/0/flow/1主机1的MAC地址:00:0c:29:91:9c:e6

【OpenDaylight】及Postman实现流表下发

2023-04-14T00:25:00+08:00
安装OVS主机名ip角色ovs192.168.123.10ovs首先连接SSH用finalshell连接，需要提前配置好ip和网卡上传ovs源文件，并解压进入目录，执行./configure，生成Makefile文件然后进入编译安装make
make install实验六-OpenDaylight及Postman实现流表下发使用Opendaylight虚拟机安装jdk1.8，并启动opendaylight安装组件：首先清理旧数据DELETE http://127.0.0.1:8181/restconf/config/opendaylight-inventory:nodes/node/openflow:1/然后CLI命令行里再次清理sudo mn -c生成拓扑并连接 OpenDaylightsudo mn --topo=single,3 --controller=remote,ip=本机ip,port=6633 --switch ovsk,protocols=OpenFlow13使用 Postman 填入 JSON 格式的 http 请求//以下内容是Body中需要填写的

"hard-timeout": "5", //此处需要修改间隔，意味着h1 ping h3 有5秒时间是中断的
"cookie": "2",

}
]
}现在CLI中h1 ping h3，再去PUT数据链接测试成功，结果符合预期鸣谢:小桂哥,King
