13、设置网络接口em2的带宽为1000±100kbps
ovs-vsctl set interface em2 ingress_policing_rate=1000
ovs-vsctl set interface em2 ingress_policing_burst=100
注：ingress_policing_rate：最大发送速率(单位均为kbps)ingress_policing_burst：超过ingress_policing_rate的最大浮动值
14、去除一个端口VLAN tag
去除从3号端口发来的所有VLAN数据包中的tag，然后转发
ovs-ofctl add-flow br0 idle_timeout=0,in_port=3,actions=strip_vlan,normal
15、给网桥添加一个端口
ovs-vsctl add-port br-int em2 把端口em2加入网桥br-int
16、给一个网桥的端口添加vlan
ovs-vsctl add-port br-int eth1 tag=2 给br-int桥的 eth1端口添加一个vlan2
