==== Mirroring ====
 
<code bash>
ovs-vsctl -- set Bridge br0 mirrors=@m \
              -- --id=@eth0 get Port eth0 \
              -- --id=@eth1 get Port eth1 \
              -- --id=@eth2 get Port eth2 \
              -- --id=@m create Mirror name=mymirror select-dst-port=@eth0,@eth1 select-src-port=@eth0,@eth1 output-port=@eth2
</code>

<code bash>
$ ovs-vsctl add-br br0
$ ovs-vsctl add-port br0 eth0
$ ovs-vsctl add-port br0 tap0
$ ovs-vsctl add-port br0 tap1 \
    -- --id=@p get port tap1 \
    -- --id=@m create mirror name=m0 select-all=true output-port=@p \
    -- set bridge br0 mirrors=@m
