This page describe how to execute <get> and <edit-config> operations about "target-output-power" XML node . via Netconf. There are totally three ways to config power.

Table of Contents

1. Environment Requirement

Docker container that runs a Netconf server. This container is considered as simulated equipment and supports some OpenConfig models.Follow the instructions posted How to build and run ODTN Emulators?
netconf-console tool that is a simulation tool for Netconf client.
"target-output-power" node defined in "openconfig-terminal-device.yang" as the operation target node.
Running ONOS instance that is able to configure power through two ways.

Assume that we have started an OpenConfig Cassini Emulator which runs a Netconf server in docker as follows:

Code Block

language	text
linenumbers	true

CONTAINER ID        IMAGE                           COMMAND                  CREATED             STATUS              PORTS       PORTS                    NAMES
00d7151855dc        emulator_openconfig_cassini_2   "./entry.sh"NAMES
20c0298eb652        onosproject/oc-cassini:0.21   "sh  9 days/root/script/pus…"   2 hours ago          Up 202 hours          22/tcp,      8080/tcp, 0.0.0.0:1100311002->830/tcp   odtn-emulator_openconfig_cassini_21_1

So we use the command listed below to send RPC request to the container:

Code Block

language	powershell

netconf-console --host=127.0.0.1 --port=11003 -u admin -p admin --rpc={XML_FILE_NAME}

The root node of "openconfig-platform.yang" is "<components>" and its sublist "<component>" contains "<name>" node as its identity. Besides, "openconfig-terminal-device.yang" adds node "<optical-channel>" into "<component>" node. "<target-power-config>" is defined as a child node of "<optical-channel>".

...

If you want to get the whole components, the content of XML_FILE_NAME file is:

Code Block

language	xml
linenumbers	true

<get>
  <filter>
    <components xmlns='http://openconfig.net/yang/platform'/>
  </filter>
</get>

If you want to get only the "<optical-channel>" of "<component>", the content is:

2 Execute Operations

2.1 ONOS startup and node discovery

This section is the environment for section 2.3 and 2.4.

Firstly, an ONOS instance is started via command "bazel run onos-local -- clean". Secondly, the docker container connects to ONOS via command "onos-netcfg localhost device.json". The content of device.json is:

Code Block

{
  "devices" : {
    "netconf:127.0.0.1:11002" : {
      "basic" : {
        "name":"cassini2",
        "driver":"cassini-ocnos"
      },
      "netconf" : {
        "ip" : "127.0.0.1",
        "port" : "11002",

Code Block

language	xml
linenumbers	true

<get>
  <filter>
    <components xmlns="http://openconfig.net/yang/platform">
      <component>
        <optical-channel xmlns="http://openconfig.net/yang/terminal-device" />"username" : "root",
      </component>
  "password"  </components>
  </filter>
</get>

The output is :

Code Block

language	xml
linenumbers	true
collapse	true

<rpc-reply xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" xmlns:nc="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="urn:uuid:c9220366-76bd-43ba-ad3c-13e1b7014e21">
  <data>
    <components xmlns="http://openconfig.net/yang/platform">: "root",
        "idle-timeout" : "0"
      }
    }
  <component>
        <optical-channel xmlns="http://openconfig.net/yang/terminal-device">}
}

Then, we use "onos localhost" to log into ONOS CLI environment and see if the docker container is detected.

2.2.1 Perform <get> Operation

Through power-config command, you can get the power value of any line-side port of any optical device, for example,

Code Block

onf@root > power-config get netconf:127.0.0.1:11002/216         <optical-channel xmlns="http://openconfig.net/yang/terminal-device">
          <config>
            <frequency>194750000</frequency>
            <target-output-power>-10.0</target-output-power>
            <line-port>oe5</line-port>
          </config>
        </optical-channel>
      </component>
      <component>
        <optical-channel xmlns="http://openconfig.net/yang/terminal-device">
          <config>
     11:56:43
The target-output-power value in port 216 on device netconf:127.0.0.1:11002 is -2.0.

2.2.2 Perform <edit-config> Operation

Through power-config command, you can modify the power value of any line-side port of any optical device, for example,

Code Block

onf@root > power-config edit-config netconf:127.0.0.1:11002/216 -4.0              <frequency>194700000</frequency>
            <target-output-power>-10.0</target-output-power>

      </component>
      <component>
        <optical-channel xmlns="http://openconfig.net/yang/terminal-device">
          <config>
            <frequency>194700000</frequency>
            <target-output-power>-10.0</target-output-power>
            <line-port>oe7</line-port>
          </config>
        </optical-channel>
      </component>
      <component>
        <optical-channel xmlns="http://openconfig.net/yang/terminal-device">
          <config>
            <frequency>194750000</frequency>
            <target-output-power>-10.0</target-output-power>
            <line-port>oe7</line-port>
          </config>
        </optical-channel>
      12:06:01
The target-output-power value in port 216 on device netconf:127.0.0.1:11002 is -4.0.

2.3 Config Power on a single device by using Netconf tool like netconf-console

So we use the command listed below to send RPC request to the container:

Code Block

language	powershell

netconf-console --host=127.0.0.1 --port=11003 -u admin -p admin --rpc={XML_FILE_NAME}

The root node of "openconfig-platform.yang" is "<components>" and its sublist "<component>" contains "<name>" node as its identity. Besides "openconfig-terminal-device.yang" adds node "<optical-channel>" into "<component>" node. "<target-power-config>" is defined as a child node of "<optical-channel>".

2.3.1 Perform <get> Operation

If you want to get the whole components, the content of get-components is:

Code Block

language	xml
linenumbers	true

<?xml version="1.0"?>
<get xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
  <filter xmlns:oc-platform="http:</component>
      <component>
        <optical-channel xmlns="http://openconfig.net/yang/terminal-deviceplatform">
          <config><oc-platform:components/>
  </filter>
</get>

You can take a look at the output of get components here: out-get-components.xml

If you want to get only the "<optical-channel>" of "<component>", the content of get-components-op-channel is:

Code Block

language	xml
linenumbers	true

<?xml version="1.0"?>
<get xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
<filter>
    <components xmlns="http://openconfig.net/yang/platform">          <frequency>194700000</frequency>
            <target-output-power>-10.0</target-output-power>
            <line-port>oe8</line-port>
          </config>
        </optical-channel>
      </component>
      <component>
        <optical-channel xmlns="http://openconfig.net/yang/terminal-device" />
      </component>
    <config></components>
  </filter>
</get>

The output is out-get-components-op-channel:

            <line-port>oe8</line-port>
          </config>
        </optical-channel>
      </component>
    </components>
  </data>
</rpc-reply>

If you want to get the "<config>" nodes only where the frequency is 194750000 and the line-port is oe1, the content of get-config-nodes is:

Code Block

language	xml
linenumbers	true

<?xml version="1.0"?>
<get xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
  <filter>
    <components xmlns="http://openconfig.net/yang/platform">
      <component>
        <optical-channel xmlns="http://openconfig.net/yang/terminal-device">
          <config>
            <line-port>oe1</line-port>
            <frequency>194750000</frequency>
          </config>
        </optical-channel>
      </component>
    </components>
  </filter>
</get>
</get>

The output is is out-get-config-nodes:

Code Block

language	xml
linenumbers	true

<nc:rpc-reply xmlns:nc="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="urn:uuid:703f18cc-512f-411c-8b8d-f07a87b4797f">

        <optical-channel xmlns="http://openconfig.net/yang/terminal-device">
          <config>
            <frequency>194750000</frequency>
            <target-output-power>-5.1</target-output-power>
            <line-port>oe1</line-port>
          </config>
        </optical-channel>
      </component>
    </components>
  </data>
</nc:rpc-reply>

2.3.2 Perform <edit-config> operation

If you want to change the target-output-power value as 0dBm instead of the default -5.1 dBm where "<name>" ID is "oe1/2", the content of file is set-target-output-power :

Code Block

language	xml
linenumbers	true

<?xml version="1.0"?>
<edit-config xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
  <target><running/></target>
  <config>
    <components xmlns="http://openconfig.net/yang/platform">
      <component>
        <name>oe1/2</name>
        <optical-channel xmlns="http://openconfig.net/yang/terminal-device">
          <config>
            <target-output-power>0</target-output-power>
          </config>
        </optical-channel>
      </component>
    </components>
  </config>
</edit-config>

The output is:

Code Block

language	xml
linenumbers	true

<rpc-reply xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" xmlns:nc="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="urn:uuid:3b4de76f-74f0-4f06-808d-64320a6c47ed">
  <ok/>
</rpc-reply>

Then we request the "<config>" nodes again to check this operation, where the frequency is 194750000 and the line-port is oe1 using get-config-nodes:

As you the following output illustrates, the target-output-power is changed from -5.1 to 0.
