OpenDaylight不会从netconf设备读取hello消息

Question

使用APIExplorer，我尝试将RESTCONF设备连接到Opendaylight。不幸的是，它的Hello消息没有被读取到功能列表中。

我让Opendaylight Neon运行每一个名称中都有“restconf”或“netconf”的功能。操作系统是Ubuntu 18.04。为了模拟netconf设备，我使用docker映像中的netopeer2（benjaminsh/netopeer2）。

我确信我拥有ODL的正确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一条hello消息，因为我在尝试SSH时会看到它。

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

我通过以下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，我尝试使用以下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消息功能中的功能，但它只是说数据模型内容不存在。

Answer 1

我找到了一个解决方案，如果其他人有类似问题，我想发布：

在查看Log in opendaylight时，我发现尝试连接到设备时存在JAVA应用程序错误。即使netconf连接器被添加到数据中，它也无法通信。

诀窍是将“key auth”更改为“login pw”。新建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"
  }
}

功能在那里：

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