ovs-vsctl设置ofport不成功处理

来源：互联网发布：成都市行知小学怎么样编辑：程序博客网时间：2024/06/06 13:15

桥结果不成功

现象：ovs-vsctl add-br br0

ovs-vsctl add-port br0 eth1

ovs-vsctl set Interface eth1 ofport_request=101

结果查询发现eth1 ofport为空

原因是未设置桥数据path类型为netdev

(2.5.0)

原因是没有设置br0 type = netdev

官方说法

<p>To use ovs-vswitchd in userspace mode, create a bridge with datapath_type "netdev" in the configuration database.

ovs-vsctl del-br br0
   73      ovs-vsctl add-br br0
   74      ovs-vsctl set bridge br0 datapath_type=netdev
   75      ovs-vsctl add-port br0 eth0
   76      ovs-vsctl add-port br0 eth1
   77      ovs-vsctl add-port br0 eth2
   78 ovs-vsctl show
   79 ovs-vsctl del-port br0 eth0
   80 ovs-vsctl del-port br0 eth1
   81 ovs-vsctl set Interface eth2 ofport_request=102
   82 ovs-vsctl get Interface eth2 ofport
