Hi

I am new to Openflow and the usage of ODL controller. I am trying to send the multipart request message via ODL controller to the Mininet, but I am not able to send OFPMPDESC, OFPMPTABLEFEATURES and OFPMPPORT_DESC request messages from the Controller.

Periodically OFPMPPORTSTATS, OFPMPFLOW and OFPMPTABLE messages are sent between the controller and the NPS after the connection establishment.

Please let me know how to generate the request messages from the ODL controller.

Thanks in advance, Swathi

Hello,

You can enable table feature using this knob: https://github.com/opendaylight/openf...

I'm not sure why you want to send those messages yourself, as ODL is sending them for you when required.

What is it you're trying to achieve?

Anyway, here are hints to create those messages:

show how to request for desc and port: https://github.com/opendaylight/openf...

show how to make empty request: https://github.com/opendaylight/openf...

translator showing how the messages gets converted: https://github.com/opendaylight/openf...

Hope this helps, Alexis
