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

登陆交换机，查看流表

ovs-ofctl dump-flows s1

删除第一条流表

删除第二条流表

http://192.168.123.10:8080/restconf/config/opendaylight-inventory:nodes/node/openflow:1/table/0/flow/2

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 OpenDaylight

sudo 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
{
    "flow": [
         {
             "id": "1",
             "match": {
                 "in-port": "1",
                 "ethernet-match": {
                     "ethernet-type": {
                         "type": "0x0800"
                     }
                 },
                 "ipv4-destination": "10.0.0.3/32"
             },
             "instructions": {
                 "instruction": [
                     {
                         "order": "0",
                         "apply-actions": {
                             "action": [
                                 {
                                     "order": "0",
                                     "drop-action": {}
                                 }
                             ]
                         }
                     }
                 ]
             },
             "flow-name": "flow1",
             "priority": "65535",
             "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",
             "table_id": "0"
         }
     ]
 }

现在CLI中h1 ping h3，再去PUT数据链接

测试成功，结果符合预期
