I can't reproduce this problem in my own testing, from a VM, just now. It's really weird that, in the case where there is an active slave, it shows its MAC as all-zeros. Do port2 actually have an all-zeros MAC? I assume not. There might be something weird even in the "working" case. _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
