Hi Ihar, Sorry for the delay. I switched my setup to devstack. Again on integrating with ODL helium release I am getting the error "*Mechanism driver 'opendaylight' failed in create_port_postcommit *." logs available at http://pastie.org/10381307 For the logs in above mail chain,you can save the image (screenshot) to get the clear view.
