Hi, Indeed ARP spoofing is prevented by default, but AFAIK, if you want it enabled for a port / network, you can simply disable the security groups on that neutron network / port.

But later in pike it was removed and it was decided to prevent spoofing by default. There are cases where security features should be disabled. As I can see now we can use a port_security option for these cases. But this option should be set for a particular port or network on create. The default value is set to True  and itt is impossible to change it. I'd like to suggest to get default value for port_security  from config option. It would be nice to know your opinion.  https://github.com/openstack/neutron-lib/blob/stable/queens/neutron_lib/api/definitions/port_security.py#L21  https://github.com/openstack/neutron/blob/stable/queens/neutron/objects/extensions/port_security.py#L24 Best regards, Tatiana
