Hello Michal,
Thanks a lot for your answer and support.
Your solution to change the basic capabilities in NetconfServerDispatcherProvider.java solved my problem.
Now I am able to mount honeycomb server into ODL.

Regards,
Saran

Hi Saran,

We use implementation of Netconf from Opendaylight. This feature is loaded from original implementation of netconf. You can take a look at https://clicktime.symantec.com/3Y2c7TnDKfb2FK447jzCEhB7Vc?u=https%3A%2F%2Fgit.opendaylight.org%2Fgerrit%2Fgitweb%3Fp%3Dnetconf.git%3Ba%3Dtree%3Bf%3Dnetconf%2Fnetconf-netty-util%2Fsrc%2Fmain%2Fjava%2Forg%2Fopendaylight%2Fnetconf%2Fnettyutil%2Fhandler%2Fexi%3Bh%3Dbad12569de87e7ba9c666d5b21ed4bceffec5220%3Bhb%3Drefs%2Fheads%2Fmaster

What you can do first is modify the default capabilities that our netconf implementation is being started with. To do this you need to change the DEFAULT_BASE_CAPABILITIES Original implementation from odl netconf:
public static final Set<String> DEFAULT_BASE_CAPABILITIES = ImmutableSet.of("urn:ietf:params:netconf:base:1.0", "urn:ietf:params:netconf:base:1.1", "urn:ietf:params:netconf:capability:exi:1.0");
to a custom set without exi:1.0
public static final Set<String> DEFAULT_ CAPABILITIES = ImmutableSet.of("urn:ietf:params:netconf:base:1.0", "urn:ietf:params:netconf:base:1.1");
You can find this in NetconfServerDispatcherProvider class. Located in honeycomb/infra/northbound/netconf/src/main/java/io/fd/honeycomb/northbound/netconf/NetconfServerDispatcherProvider.java

This should be enough and honeycomb shouldn't report this capability anymore. Since this hasn't been used in honeycomb it shouldn't be a problem if the feature is removed. However I haven`t tested this so I am not sure what this will cause. And if netconf has some internal dependencies on this feature you may run into other errors. You would need to test this by yourself.

Hopefully this will work. But if it doesnt the other options would be to create a dummy handler for this feature in honeycomb (or try to do a propper full implementation). Next option is to modify the Netconf implementation in honeycomb to remove this feature (not sure if this is possible and how hard it can be). Or you can build your own version of netconf without the exi support and built honeycomb on top of it.

Hello Team/ Marek,

I have developed a simulator using honeycomb 08_10 version and testing it with opendaylight controller.

Honeycomb agent is sending "urn:ietf:params:netconf:capability:exi:1.0" as part of initial <hello> message.
So opendaylight start sending binary request data as described in https://clicktime.symantec.com/3DWmpigZygsWXTdQEQrgG6Z7Vc?u=https%3A%2F%2Ftools.ietf.org%2Fid%2Fdraft-varga-netconf-exi-capability-00.html%23W3C.REC-exi-20110310 to honeycomb agent and I am getting deserialization exception in Honeycomb while reading this binary request data.

I have following questions:
1. I would like to remove this "urn:ietf:params:netconf:capability:exi:1.0" capability from the <hello> message. Where in honeycomb code this capability is mentioned?
2. Is this W3C.REC-exi-20110310 EXI feature really supported in honeycomb? If so, why I am getting deserialization exception?

Regards,
Saran

Hello Saran,

generating netconf agent based on custom model is not supported.

But feel free to create jira ticket if you are interested in the feature.
Contributions to design/implementation are welcomed!

Currently Honeycomb plugin archetype generates maven project structure, code and documentation only for the sample model (parametrized by root artifact id):

Hello Team,



I am using honeycomb 18.07 version. Trying to bring up Netconf server for my own yang model file.



I modified the “honeycomb/enodebsim/enodebsim-api/src/main/yang/enodebsim.yang” file with my yang content.

Then I did the following:

$cd honeycomb/

$ rm enodebsim/pom.xml enodebsim/enodebsim-api/pom.xml

$ vi pom.xml #removed the enodebsim from Module list

$ mvn -X archetype:generate
-DarchetypeGroupId=io.fd.honeycomb.tools
-DarchetypeArtifactId=honeycomb-plugin-archetype
-DarchetypeVersion=1.18.10-SNAPSHOT -DinteractiveMode=false
-DgroupId=org.onap.ransim -DartifactId=enodebsim
-Dversion=1.0.0-SNAPSHOT -Dpackage=org.onap.ransim

$cd honeycomb/enodebsim/

$mvn clean install



This generated the java files for my new yang model. However the code generated in “honeycomb/enodebsim/enodebsim-impl” is not referring my new yang model. It still uses the old sample yang model.



Will the generate netconf agent automatically includes new yang model into capabilities?



Pls let me know if I missed any steps. If you can share the link/doc explaining what needs to be done for custom yang model simulation?





Regards,
Saran
