OpenDaylight不读取来自netconf设备的问候消息

Question

使用APIExplorer，我尝试将RESTCONF设备连接到Opendaylight。不幸的是，它的Hello消息没有读入到capabilities列表中。

我让Opendaylight Neon运行每个名称中有"restconf“或"netconf”的功能。操作系统为Ubuntu 18.04。为了模拟netconf设备，我使用了docker镜像中的netopeer2 (benjaminsh/netopeer2)。

我确信我拥有正确的ODL IP，因为我能够连接和接收拓扑数据。此外，我确信我的模拟设备会给出hello消息，因为我可以在尝试SSH进入它时看到它。

我使用以下命令启动docker容器：

sudo docker run -it --name netopeer2 -p 1831:830 --rm benjaminsh/netopeer2:latest

我通过这个REST命令添加netconf设备：

post /restconf/operations/netconf-node-topology:create-device 
    {
    "netconf-node-topology:input": {
    "netconf-node-topology:pass-through": {},
    "key-based": {
      "netconf-node-topology:key-id": "netconf",
      "netconf-node-topology:username": "netconf"
    },
    "netconf-node-topology:host": "192.168.56.2",
    "netconf-node-topology:port": "830",
    "netconf-node-topology:tcp-only": "false",
    "netconf-node-topology:reconnect-on-changed-schema": "false",
    "netconf-node-topology:connection-timeout-millis": "20000",
    "netconf-node-topology:max-connection-attempts": "0",
    "netconf-node-topology:between-attempts-timeout-millis": "2000",
    "netconf-node-topology:sleep-factor": "1.5",
    "netconf-node-topology:keepalive-delay": "120",
    "netconf-node-topology:node-id": "new-netconf-device"
      }
    }

之后，我尝试使用下面的REST命令访问收到的hello消息中的功能：

get /restconf/config/network-topology:network-topology/topology/topology-netconf/node/new-netconf-device/netconf-node-topology:odl-hello-message-capabilities

我希望看到odl-hello-message-capabilites中的功能，但它只是说明数据模型内容不存在。

Answer 1

我找到了一个解决方案，我想在其他人遇到类似问题的情况下发布：

在opendaylight中查看日志时，我发现在尝试连接到该设备时存在JAVA应用程序错误。即使将netconf连接器添加到数据中，它也不能通信。

诀窍是将"key-auth“改为"login-pw”。新的REST命令：

post /restconf/operations/netconf-node-topology:create-device 
{
  "netconf-node-topology:input": {
    "netconf-node-topology:pass-through": {},
    "login-password": {
      "netconf-node-topology:username": "netconf",
      "netconf-node-topology:password": "netconf"
    },
    "netconf-node-topology:host": "192.168.56.2",
    "netconf-node-topology:port": "1831",
    "netconf-node-topology:tcp-only": "false",
    "netconf-node-topology:reconnect-on-changed-schema": "false",
    "netconf-node-topology:connection-timeout-millis": "20000",
    "netconf-node-topology:max-connection-attempts": "0",
    "netconf-node-topology:between-attempts-timeout-millis": "2000",
    "netconf-node-topology:sleep-factor": "1.5",
    "netconf-node-topology:keepalive-delay": "120",
    "netconf-node-topology:node-id": "new-netconf-device"
  }
}

功能已经具备了：

get /restconf/operational/network-topology:network-topology
