[ovs-discuss] OpenvSwitch port mirroring virtual interfaces to physical interface

[Justin Pettit]

OVS shouldn't have any problem mirroring to physical ports.  You may want to make sure that there aren't any MTU issues (i.e., the MTU on the taps is larger than eth0).

But we meet some problems which you all help us. In our host, which installed ovs, have 3 virtual interfaces (tap0 - tap2) and 2 physical interface (eth0, eth1). We have added tap0-tap2, eth0, eth1 to bridge br0. Our ovs could mirror the traffic from tap0 and tap1 to tap2 successfully but mirror the same traffic to eth1 will not work. Could ovs mirror VM traffic to physical interface? Or we have some basic concept need to be clear?
