This page describe how to execute <get> and <edit-config> operations about "target-output-power" XML node. 


Environment Requirement

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

CONTAINER ID        IMAGE                           COMMAND                  CREATED             STATUS                     PORTS                    NAMES
00d7151855dc        emulator_openconfig_cassini_2   "./entry.sh"             9 days ago          Up 20 hours                0.0.0.0:11003->830/tcp   emulator_openconfig_cassini_2_1

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

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>".


Performing <get> Operation:


  • If you want to get the whole components, the content of XML_FILE_NAME file is:
<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:
<get>
  <filter>
    <components xmlns="http://openconfig.net/yang/platform">
      <component>
        <optical-channel xmlns="http://openconfig.net/yang/terminal-device" />
      </component>
    </components>
  </filter>
</get>

The output is :

<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">

  • If you want to get the "<config>" nodes only where the frequency is 0 and the line-port is oe1:
<?xml version="1.0"?>
<get>
  <filter>
    <components xmlns="http://openconfig.net/yang/platform">
      <component>
        <optical-channel xmlns="http://openconfig.net/yang/terminal-device">

    </components>

</get>

The output is:

<edit-config> operation

  • If you want to change the target-output-power value as 0dBm instead of the default -10.0 dBm where "<name>" ID is "oe1/2":
<?xml version="1.0"?>
<edit-config>
  <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:

<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 0 and the line-port is oe1. The output is changed:
