Did you take a look at ask.openstack.org? I see
https://ask.openstack.org/en/question/3239/how-to-change-status-of-a-neutron-port-from-down-to-active/has
helped a few people recently.
There's a related bug, https://bugs.launchpad.net/neutron/+bug/1192883,
with a fix commited for h3.

And the answer for one person was "when the netmask of the public subnet
and gateway were mismatched. Make sure the IP subnetting is done right,
otherwise the port will stay down whatever you do.

If you find the mistake, delete the network, subnet, router, ports, etc and
create them again."
