使用“ovs-vsctl show”命令找不到OVSDB创建的OVS网桥答案

【问题标题】：Use the "ovs-vsctl show" command can not find OVS bridge that created by OVSDB使用“ovs-vsctl show”命令找不到OVSDB创建的OVS网桥
【发布时间】：2018-12-17 07:28:26
【问题描述】：

我使用OVSDB Southbound Plugin RESTAPI来创建桥接如下：

HTTP PUT:http://<controller-ip>:8181/restconf/config/networktopology:network-topology/topology/ovsdb:1/node/ofconfig％2Fbridge％2Fbrtest
Body:{"network-topology:node": [
{
  "node-id": "ofconfig％2Fbridge％2Fbrtest",
  "ovsdb:bridge-name": "brtest",
  "ovsdb:protocol-entry": [
    {
      "protocol": "ovsdb:ovsdb-bridge-protocol-openflow-13"
    }
  ],
  "ovsdb:managed-by": "/network-topology:network-topology/network-topology:topology[network-topology:topology-id='ovsdb:1']/network-topology:node[network-topology:node-id='ofconfig']"
}]}

结果是 201 Created。但是当我在 OVS 主机中使用“ovs-vsctl show”命令时，我找不到“brtest”网桥。所以，任何人都可以帮助我解决这个问题。谢谢！

【解决方案1】：

你的 ovs 连接了吗？即使没有连接开关，它仍然是可能的在配置存储中创建一个网桥。

从操作存储中对拓扑执行 GET 操作，看看您是否有权限节点id等URI应该是：

/restconf/operational/network-topology:network-topology/topology/ovsdb:1

仅看到 ovsdb:1 并不表示您的 ovs 已连接。那只是表示您实际上是在 odl 中运行 ovsdb 南行。

我安装了 ovsdb 并且没有连接 ovs 的设置示例：

# curl -u admin:admin http://localhost:8181/restconf/operational/network-topology:network-topology/topology/ovsdb:1 | python -m json.tool 

{
    "topology": [
        {
            "topology-id": "ovsdb:1"
        }
    ]
}

现在，连接我的 ovs：

# ovs-vsctl set-manager tcp:127.0.0.1:6640
# ovs-vsctl show | egrep connec
        is_connected: true
# ovs-vsctl show
28bde339-8db8-4848-a1fc-4a9ecc81b5c3
    Manager "tcp:127.0.0.1:6640"
        is_connected: true
    ovs_version: "2.9.0"

    ]
}

请注意 ovs-vsctl show 说 is_connected: true，并注意实际的节点 ID

【讨论】：

是的，我确定我的 ovs 已连接。因为当我在 Karaf 中安装 odl-ovsdb-southbound-impl-ui 时，我在拓扑上执行 GET 我可以看到“topology-id”的“ovsdb:1”。
