    1010`of1` shows up as DPID 00:00:00:23:20:08:0f:f7 on `kvm-big`. On `of1`, this is the MAC address of interface tap0. [[BR]]
    11 The following flow entries are created for `of1`'s DPID on `kvm-big`:

     20From the config-switch context, two flow entries are created for `of1`'s DPID on `kvm-big`: one for switching VLAN tags from 3733 to 5 on nf2c2, and the other, from 5 to 3733 on nf2c1.

     34Setting flow entries from the `config-switch` context is a matter of copy/pasting each line above, and exiting between different flow entries. Key points are:
     35 * The four ports of the NetFPGA are designated 1,2,3,4, not 0,1,2,3 as the nf2cx numbering might suggest. 
    3436 * 'active True' must be specified to enable the flow policy since the default for any newly created flow is 'active False'
    3537 * at least one layer 2 or lower constraint e.g. ingress/egress port or src/dst MAC must be specified
