floodlight 流表

当floodlightdefault.properties配置文件中加载了转发模块(net.floodlightcontroller.forwarding.Forwarding).则连接在交换机上的PC机是可以互相ping通的.floodlight中没有加载此模块时,须要用使添加流表来控制流向.下面介绍一下从控制器端对openflow交换机添加与删除流表.

　　添加流表:

　　[controller@host ]# curl -d '{"switch": "00:00:00:00:00:00:00:01", "name":"flow-mod-1", "cookie":"0", "priority":"2232", "ingress-port":"1","active":"true", "actions":"output=2"}' http://:8080/wm/staticflowentrypusher/json

　　[controller@host ]# curl -d '{"switch": "00:00:00:00:00:00:00:01", "name":"flow-mod-2", "cookie":"0", "priority":"2232", "ingress-port":"2","active":"true", "actions":"output=1"}' http://:8080/wm/staticflowentrypusher/json

　　这两条流表为1号端口的流向2号接口,2号端口的流向1号接口.

　　连接在这两个接口上的PC机可以互相通信.

　　可变参数解析:

　　"00:00:00:00:00:00:00:01"为openflow交换机与controller交互所产生的DPID.

　　"flow-mod-1"为该流表的名字(索引),后可用此名字(索引)来删除该流表.

　　"ingress-port":后面的参数为入接口

　　"actions":后面的参数为出接口

　　填入controller的IP

　　读取流表:

　　[controller@host ]# curl http://192.168.1.100:8080/wm/core/switch/1/flow/json

　　[controller@host ]# curl http://192.168.1.100:8080/wm/staticflowentrypusher/list/all/json

　　删除流表:

　　1.删除所有流表

　　[controller@host ]# curl http://192.168.1.208:8080/wm/staticflowentrypusher/clear//json

　　2.删除单条流表

　　[controller@host ]# curl -X DELETE -d '{"name":"flow-mod-1"}' http://:8080/wm/staticflowentrypusher/json
