ovs-vsctl add-port ovs11 ens36
ovs-vsctl show
ovs_server02
ovs-vsctl add-port ovs12 ens36
ovs-vsctl show
(6)ODL查看

(7) 查看OVS流表节点
ovs_server01
ovs-ofctl show ovs11 -O OpenFlow13
ovs_server02
ovs-ofctl show ovs12 -O OpenFlow13
(8) 查看OVS流表信息
ovs_server01
ovs-ofctl dump-flows ovs11 -O OpenFlow13
ovs_server02
ovs-ofctl dump-flows ovs12 -O OpenFlow13
(9)LLDP流量抓包
ovs_server01 的MAC地址为00:0c:29:50:7a:08,openflow流表为52232747528
ovs_server02的MAC地址为 00:0c:29:d5:c1:24 ,openflow流表为52241482020
(9)服务端云交换机添加接口
ovs_server01
ovs-vsctl add-port ovs11 if11 -- set interface if11 type=internal
