必须得搞搞odl了

安装

后台启动

./bin/start

控制台

后台启动时怎么登录控制台？

./bin/client

NETCONF设备

分两种

模拟设备

模拟netconf设备有多种方式，这里采用的是odl提供的netconf-testtool，文档见这里

下载testtool，我下载的是最新版，老版本的ODL需要注意下

https://nexus.opendaylight.org/content/repositories/public/org/opendaylight/netconf/netconf-testtool

启动

java -jar netconf-testtool-1.8.2-executable.jar

# 启动情况如下
root@localhost:~/odljava -jar netconf-testtool-1.8.2-executable.jar 
10:42:59.373 [main] INFO  o.o.n.t.tool.NetconfDeviceSimulator - Starting 1, SSH simulated devices starting on port 17830
10:42:59.398 [main] INFO  o.o.n.t.tool.NetconfDeviceSimulator - Custom module loading skipped.

10:43:00.143 [main] INFO  o.o.n.t.tool.NetconfDeviceSimulator - All simulated devices started successfully from port 17830 to 17830

启动后默认启动了一个支持netconf的设备，默认端口17830

测试

ssh admin@localhost -p 17830 -s netconf

# 测试如下
root@localhost:~/odl/opendaylight-0.12.2/cache/schema# ssh root@localhost -p 17830 -s netconf
The authenticity of host '[localhost]:17830 ([127.0.0.1]:17830)' can't be established.
RSA key fingerprint is SHA256:+sqmaHkirjlLQdYJfKcYB677cMK2Hgdkq+9ZarwL/oY.
Are you sure you want to continue connecting (yes/no)?

显示以上信息，即netconf设备启动成功。

具体绑定设备见下面

另外官网文档说指定--distribution-folder就可自动绑定，但我测试未生效

java -jar netconf-testtool-1.8.2-executable.jar --device-count 2 --distribution-folder ~/odl/opendaylight-0.12.2/ --md-sal MD-SAL --debug DEBUG

实体设备

这里叫实体设备，不太合适，也是由eve-ng模拟的。但其具备和实体设备一样的功能，一样的配置。

采用的是ios xr，具体安装见这里

安装完后的拓扑见

绑定NETCONF设备

由于是开源的软件，文档更新速度，千百个草泥马。按官网文档从上到下是配置不成功的，新的架构已经改为MD-SAL模式，故直接跳到这个地方

这里很简单，我觉得分2步

odl安装feature

feature:install odl-restconf odl-netconf-connector-all odl-netconf-topology odl-netconf-console odl-mdsal-apidocs

其中

odl-restconf: 支撑的是北向restful的接口
odl-mdsal-apidocs: 提供API DOC, 通过web ui登录
- 地址：http://<odl-ip>:8181/apidoc/explorer/index.html
- username: admin password: admin

启用log

karaf shell界面执行

log:set TRACE org.opendaylight.controller.sal.connect.netconf

接入odl

node文件

<node xmlns="urn:TBD:params:xml:ns:yang:network-topology">
  <node-id>new-netconf-device1</node-id>
  <host xmlns="urn:opendaylight:netconf-node-topology">127.0.0.1</host>
  <port xmlns="urn:opendaylight:netconf-node-topology">17830</port>
  <username xmlns="urn:opendaylight:netconf-node-topology">root</username>
  <password xmlns="urn:opendaylight:netconf-node-topology">xxx</password>
  <tcp-only xmlns="urn:opendaylight:netconf-node-topology">false</tcp-only>
  <!-- non-mandatory fields with default values, you can safely remove these if you do not wish to override any of these values-->
  <reconnect-on-changed-schema xmlns="urn:opendaylight:netconf-node-topology">false</reconnect-on-changed-schema>
  <connection-timeout-millis xmlns="urn:opendaylight:netconf-node-topology">20000</connection-timeout-millis>
  <max-connection-attempts xmlns="urn:opendaylight:netconf-node-topology">0</max-connection-attempts>
  <between-attempts-timeout-millis xmlns="urn:opendaylight:netconf-node-topology">2000</between-attempts-timeout-millis>
  <sleep-factor xmlns="urn:opendaylight:netconf-node-topology">1.5</sleep-factor>
  <!-- keepalive-delay set to 0 turns off keepalives-->
  <keepalive-delay xmlns="urn:opendaylight:netconf-node-topology">120</keepalive-delay>
</node>

以下接口调用的header指定如下,

Accept application/xml
Content-Type application/xml

添加node

这里是put方法，多次提交是修改之前的，没有node的话则新建，这里注意

获取看看

成功了！且我们能看到设备提供的netconf能力，这里我折叠了。

现在，mount点 yang-ext:mount 将可用于 CONFIG 和 Operational data store. URI这样：/topology-netconf/node/{node name}/yang-ext:mount/

至此，设备绑定上了，亦或被ODL接管了。

删除node

指定对应的node name，delete方法即可删除

南向接口调用

创建YANG文件

进入odl的scheme目录

cd ~/odl/opendaylight-0.12.2/cache/schema

创建yang model，这里起了个简单的

vim test@2014-10-17.yang

输入下面内容

module test {
    yang-version 1;
    namespace "urn:opendaylight:test";
    prefix "tt";

    revision "2014-10-17";


   container cont {

        leaf l {
            type string;
        }
   }
}
