OpenFlow 拓扑中没有节点：
opendaylight-user@root>openflow:getallnodes
No node is connected yet
opendaylight-user@root>
在网络上，我看到控制器和交换机之间的 OpenFlow 数据包：

现在，在 Open vSwitch 方面：
# ovs-vsctl show
934472aa-72ca-4f61-834c-a86bd41a9b27
Manager "tcp:10.10.10.20:6640"

Interface "0de326ec0ace4_l"
Port "vsw0"
Interface "vsw0"
type: internal
ovs_version: "2.9.0"
控制器从 ACTIVE 变为 IDLE：
# ovs-vsctl list controller

connection_mode : []

other_config : {}
role : other
status : {sec_since_connect="42353", state=ACTIVE}
target : "tcp:10.10.10.20:6653"
日志显示如下。

任何想法为什么没有形成 OF 连接？
