[openstack-dev] [Neutron] Chalenges with highly available service VMs - port adn security group options.

I have completely missed this discussion as it does not have quantum/Neutron in the subject (modify it now)
I think that the security group is the right place to control this.
I think that this might be only allowed to admins.

Let me explain what we need which is more than just disable spoofing.

1.       Be able to allow MACs which are not defined on the port level to transmit packets (for example VRRP MACs)== turn off MAC spoofing

2.       Be able to allow IPs which are not defined on the port level to transmit packets (for example, IP used for HA service that moves between an HA pair) == turn off IP spoofing

3.       Be able to allow broadcast message on the port (for example for VRRP broadcast) == allow broadcast.

Yes - have you got docs on the port security extension?  All I've
found so far are
and the fact that it's only the Nicira plugin that implements it.  I
could implement it for something else, but not without a few hints...
