Also check the status of neutron-openvswitch-agent

[Hirofumi Ichihara (ichihara-hirofumi)]

Maybe it's linuxbridge. Could you find error in linuxbridge-agent log?

[Ali Jabbar (jabbar-ali)]

Yes, It is linux bridge setup in a single node

[sarvani konda (sarvani)]

As per the bug description we reproduced the issue in single node mitaka (neutron version-4.1.1) set up with linux bridge as ml2 agent, we have observed that there is no failure of port binding and it was according to the expected behavior. could you let us know if anything additional is required to analyze.

[Ihar Hrachyshka (ihar-hrachyshka)]

The sarvani's analysis suggests it works fine. I see we miss neutron-server logs in the bug that would reveal the reason for binding failure. I am moving the bug to Incomplete. If it still affects you on a release supported for regular bug fixes (Ocata, Pike, Queens at the time of writing), please upload new logs, for l2 agents as well as neutron-server.
