Hi Rajendra,
Your Template seems to be ok. Please check your CM request. Can you share the
error log?
Sample CM request,
{
"version": "2.0",
"type": "request",

"action-identifiers": {
"vnf-id": "074e192d-8704-47c8-a910-682539e2e87d"
},
"payload":
"{\"request-parameters\":{\"vnf-host-ip-address\":\"10.12.6.0\"},\"configuration-parameters\":{\"status\":\"true\"}}"
}
}
}
In CDT you create the template with this parameters (highlighted in Yellow) and
expect the values to be passed during runtime in CM request.
If I understand correctly, in your scenario the payload should be something
like,
"{\"request-parameters\":{\"vnf-host-ip-address\":\"192.168.122.238\"},\"configuration-parameters\":{\"
id_val \":\"01\",\" enabled_val \":\"true\"}}"
However I’m not sure what ‘s the Netconf Message is. Its just a guess based on
limited input available in the email. Thanks!
Br,

Lathish, thank you for the detailed answers. I modified my template based on
your description, however it still fails.
Can you share the template & request for ConfigModify if you have one.
The request that I post on DMAAP.

Hi RP,
For Netconf-XML, you no need URL. You need to fill in the USER_NAME, PASSWORD,
PORT_NUMBER. APPC identifies the VNF/PNF from AAI or from the Config Modify
Request.
This will be configured during Design time in CDT.
Please find the response below.

Subject: Re: [onap-discuss] [APPC] [CDT] [PNF] ConfigModify LCM command fails
on PNF
Thanks Taka. That was helpful.
I added the DEVICE_INTERFACE_PROTOCOL entry in the DB and it moved further.
Additionally, it was failing to identify the URL so I added the following entry
in DEVICE_AUTHENTICATION in appc db. I hope this is correct.
update DEVICE_AUTHENTICATION set PASSWORD="netconf", URL="192.168.122.238"
where DEVICE_AUTHENTICATION_ID=55;
MariaDB [sdnctl]> select * from DEVICE_AUTHENTICATION ;
+--------------------------+----------+-------------+--------------+-----------+----------+-------------+-----------------+
| DEVICE_AUTHENTICATION_ID | VNF_TYPE | PROTOCOL | ACTION | USER_NAME
| PASSWORD | PORT_NUMBER | URL |
+--------------------------+----------+-------------+--------------+-----------+----------+-------------+-----------------+
| 55 | vFW | NETCONF-XML | ConfigModify | netconf
| netconf | 830 | 192.168.122.238 |
With all these changes I am able to move further. However, it still fails to
connect to the PNF simulator.
I have a few questions.
1. How does CDT/APPC know about the URL for which we are doing the ConfigModify
action. There is no field in CDT to fill in the info. It only asks for
"Username" and "Port" in the CDT gui.
[Lathish] : This is done during the design time in CDT. After you enter
Username & Port. You have the option to define how the parameter values will be
filled during Runtime. Either manual or from AAI. If you set it as Manual then,
in the CM request you need to pass the vnf-host-ip-address(VNF/PNF IP) in the
payload.
2. What is the expectation from the PNF/VNF for accepting the NETCONF-XML
protocol. Is there a way to verify whether PNF/VNF is listening for our request.
[Lathish] : VNF/PNF with Netconf-xml protocol, you can do ssh to connect to the
host and verify it. I can share the NETCONF message if you want.
3. Currently I am posting the ConfigModify request on DMAAP. However, in the
eventual scheme who triggers the LCM configModify ? How is it used with real
VNF's ?
[Lathish] : It depends upon your use case. For now we have a use case where
policy triggers CM.
4. We have tested ModifyConfig with RESTCONF and closed loop. How can we use
RESTCONF from CDT ? When I choose the RESTCONF protocol it fails (log says
"Error occurred in processFlow java.lang.Exception: Don't know how to execute
transaction ID 1). Do we need to do something different in case of RESTCONF and
ConfigModify LCM in CDT/APPC.
[Lathish] : First you need to mount the node in APPC to trigger RESTCONF. I
haven’t tried RESTCONF from APPC LCM.
Below is the snippet of the log failure when we do ConfigModify with
NETCONF-XML (The full log is attached)

should work.

Subject: [onap-discuss] [APPC] [CDT] [PNF] ConfigModify LCM command fails on PNF
Hi,
I am trying to do ConfigModify LCM using CDT in ONAP CASABLANCA. I am
using a "PNF simulator" instead of VNF.
When we POST the configModify command on DMAAP, APPC looks for the "vnf"
related information from AAI.
To workaround that, we populated the PNF information in AAI.
With above changes I am able to post the ConfigModify request to DMAAP, and
then APPC picks it up and processes it.
However, APPC fails to complete the request. Below is the snippet of the log.
Looks like APPC failed at "GetAaiInfo"
The full log is also attached.
Taka, Marco and other members of APPC team, request your help.
