<p class="MsoNormal">Yes - have you got docs on the port security extension? All I've<br>
found so far are<br>
<a href="http://docs.openstack.org/developer/quantum/api/quantum.extensions.portsecurity.html" target="_blank">http://docs.openstack.org/developer/quantum/api/quantum.extensions.portsecurity.html</a><br>
and the fact that it's only the Nicira plugin that implements it. I<br>
could implement it for something else, but not without a few hints...<br>
