必須得搞搞odl了

後臺啓動
./bin/start
控制檯
後臺啓動時怎麼登錄控制檯？
./bin/client
NETCONF設備
分兩種
模擬設備
模擬netconf設備有多種方式，這裏採用的是odl提供的netconf-testtool，文檔見這裏
下載testtool，我下載的是最新版，老版本的ODL需要注意下
https://nexus.opendaylight.org/content/repositories/public/org/opendaylight/netconf/netconf-testtool
啓動
java -jar netconf-testtool-1.8.2-executable.jar
# 啓動情況如下
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.
10:42:59.880 [main] INFO o.o.n.t.tool.NetconfDeviceSimulator - using OperationsProvider.
10:42:59.978 [main] INFO o.o.n.s.s.c.u.s.b.BouncyCastleSecurityProviderRegistrar - getOrCreateProvider(BC) created instance of org.bouncycastle.jce.provider.BouncyCastleProvider
10:42:59.980 [main] INFO o.o.n.s.s.c.u.s.e.EdDSASecurityProviderRegistrar - getOrCreateProvider(EdDSA) created instance of org.opendaylight.netconf.shaded.eddsa.EdDSASecurityProvider
10:43:00.063 [main] WARN io.netty.bootstrap.ServerBootstrap - Unknown channel option 'SO_BACKLOG' for channel '[id: 0x2c47b0bf]'
10:43:00.143 [main] INFO o.o.n.t.tool.NetconfDeviceSimulator - All simulated devices started successfully from port 17830 to 17830
啓動後默認啓動了一個支持netconf的設備，默認端口17830
測試
ssh admin@localhost -p 17830 -s netconf
# 測試如下
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)?
顯示以上信息，即netconf設備啓動成功。
具體綁定設備見下面
另外官網文檔說指定--distribution-folder就可自動綁定，但我測試未生效
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
實體設備
這裏叫實體設備，不太合適，也是由eve-ng模擬的。但其具備和實體設備一樣的功能，一樣的配置。
採用的是ios xr，具體安裝見這裏
安裝完後的拓撲見
綁定NETCONF設備
由於是開源的軟件，文檔更新速度，千百個草泥馬。按官網文檔從上到下是配置不成功的，新的架構已經改爲MD-SAL模式，故直接跳到這個地方
這裏很簡單，我覺得分2步
odl安裝feature
feature:install odl-restconf odl-netconf-connector-all odl-netconf-topology odl-netconf-console odl-mdsal-apidocs
其中
- odl-restconf: 支撐的是北向restful的接口
- odl-mdsal-apidocs: 提供API DOC, 通過web ui登錄
- 地址：http://<odl-ip>:8181/apidoc/explorer/index.html
- username: admin password: admin
![]()
啓用log
karaf shell界面執行
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>
以下接口調用的header指定如下,
Accept application/xml
Content-Type application/xml
添加node
這裏是put方法，多次提交是修改之前的，沒有node的話則新建，這裏注意
獲取看看
成功了！且我們能看到設備提供的netconf能力，這裏我摺疊了。
現在，mount點 yang-ext:mount 將可用於 CONFIG 和 Operational data store. URI這樣：/topology-netconf/node/{node name}/yang-ext:mount/
至此，設備綁定上了，亦或被ODL接管了。
刪除node
指定對應的node name，delete方法即可刪除
南向接口調用
創建YANG文件
進入odl的scheme目錄
cd ~/odl/opendaylight-0.12.2/cache/schema
創建yang model，這裏起了個簡單的
vim [email protected]
輸入下面內容
module test {
yang-version 1;
namespace "urn:opendaylight:test";
prefix "tt";
revision "2014-10-17";
container cont {
leaf l {
type string;
}
}
}
重啓ODL
system:shutdown
測試
注意這裏是POST方法
驗證,看下面已經推進去了
