    16 First we will establish rules for allowing IP traffic to flow between host1 and host2. Later in the howto we will discuss how to setup the OVS switch to allow for host3 to observe the traffic between host1 and host2 using OpenFlow table rules. An alternative method using the Mirror feature of the OVS switch is also presented if only mirroring is required.  These setups maybe be used for network monitoring.

    120 There are two possible ways in which port mirroring can be setup using an OVS switch. The first method presented uses OpenFlow table rules. An alternative method is presented that does not use OpenFlow at all.

    139 It is possible to setup mirroring without ever adding any flows to the OpenFlow table. It can be done independently of setting up the static IP flows. This is done with a single command to ovs-vsctl.
