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. 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.

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",
        "username" : "root",
        "password" : "root",
        "idle-timeout" : "0"
      }
    }
  }
}

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

Hit '<tab>' for a list of available commands
and '[cmd] --help' for help on a specific command.
Hit '<ctrl-d>' or type 'logout' to exit ONOS session.

onf@root > devices       

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

Code Block
languagepowershell
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>".

2.1.1 Perform <get> Operation

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

Code Block
languagexml
linenumberstrue
<?xml version="1.0"?>
<get xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
  <filter xmlns:oc-platform="http://openconfig.net/yang/platform">
    <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
languagexml
linenumberstrue
<?xml version="1.0"?>
<get xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
<filter>
    <components xmlns="http://openconfig.net/yang/platform">

        <optical-channel xmlns="http://openconfig.net/yang/terminal-device" />
      </component>
    </components>
  </filter>

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          <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>
            <frequency>194700000</frequency>
  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  <target-output-power>-10.0</target-output-power>
            <line-port>oe6</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>oe6</line-port>
    12:04:11
onf@root > power-config get netconf:127.0.0.1:11002/216       </config>
          </optical-channel>
      </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</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
languagepowershell
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
languagexml
linenumberstrue
<?xml version="1.0"?>
<get xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
  <filter xmlns:oc-platformtarget-output-power>
            <line-port>oe7</line-port>
          </config>
        </optical-channel>
      </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
languagexml
linenumberstrue
<?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:

Code Block

          </config>
        </optical-channel>
 <component>
     </component>
    </components>

2.1.2 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
languagexml
linenumberstrue
<?xml version="1.0"?>
<edit-config xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
  <target><running/></target>
  <config>

            <frequency>0</frequency>
            <target-output-power>-10.0</target-output-power>
            <line-port>oe2</line-port>
          </config>
        </optical-channel>
      <component></component>
        <name>oe1/2</name><component>

            <target-output-power>-10.0</target-output-power>
            <line-port>oe3</line-port>
          </config>
        </optical-channel>
      </component>
      </components><component>
  </config>
</edit-config>

The output is:

Code Block

linenumberstrue
<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.

2.2 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" : {
      <optical-channel xmlns="http://openconfig.net/yang/terminal-device">
          <config>
          "basic" : {
    <frequency>194700000</frequency>
    "name":"cassini2",

      },
      "netconf" : {<line-port>oe5</line-port>
        "ip" : "127.0.0.1", </config>
        "port" : "11002",

        "idle-timeout" : "0"<config>
      }
    }
  }
}

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

2.3 Config Power by using ONOS CLI Command "power-config"

An ONOS command is provided to configure the power of line-side ports.

In ONOS CLI environment, the description for command "power-config" is listed:

Code Block
onf@root > help power-config<frequency>194700000</frequency>

2.3.1 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 </config>
        </optical-channel>
      </component>
                                                                                                11:56:43
The </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
languagexml

<edit-config xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
  <target><running/></target>
  <config>
    <components xmlns="http://openconfig.net/yang/platform">
      <component>

2.3.2 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                                                                                                   12:04:11
onf@root > power-config get netconf:127.0.0.1:11002/216                                              <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>
       12:06:01
The target-output-power value in port 216 on device netconf:127.0.0.1:11002 is -4.

2.4 Config Power on ONOS roadm GUI2 pages

Apart from configuring the power in ONOS CLI, the customer view of roadm application also provides the button to do that.

Firstly, we use command "onos localhost app activate roadm" to activate roadm application. Then, open the roadm page http://localhost:8181/onos/ui/#/roadm-gui:

Image Removed

Select one device netconf:127.0.0.1:11002, and click the port icon on the right-top corner, then you can edit the power of its line-side ports on port page http://localhost:8181/onos/ui/#/roadm-gui/roadm-port-gui?devId=netconf:127.0.0.1:11002. The client-side ports couldn't be edited (see port 116).

</components>
  </config>
</edit-config>


The output is:

Code Block
languagexml
linenumberstrue
<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.Image Removed
