    185185Information in the output manifest files provides the switch and the port information to be used in making the OF flowspace reservation.

    187 '' ''' Step 2''' ''. Review [http://groups.geni.net/geni/wiki/GeniAggregate GeniAggregate] to determine MyPLC hosts mapping to the Site's OpenFlow switch. In the [http://groups.geni.net/geni/wiki/GeniAggregate GeniAggregate] page, select the OF Aggregate link for BBN, Clemson and Wisconsin and use the OF site diagrams to determine which ports and DPID should be used in the OF RSpec. 
    188 
    189 Let map the 3 nodes from the Site's compute resources RSpec.
     187'' ''' Step 2''' ''. Define site specific OF details based on [http://groups.geni.net/geni/wiki/GeniAggregate GeniAggregate] and   MyPLC hosts mapping to the Site's OpenFlow switch.  This step walk through how the site details are defined. In the [http://groups.geni.net/geni/wiki/GeniAggregate GeniAggregate] page, select the OF Aggregate link for BBN, Clemson and Wisconsin and use the OF site diagrams to determine which ports and DPID should be used in the OF RSpec.

     189Let map the 3 nodes from the Site's compute resources RSpec to the appropriate OF Switch port and determine how they connect to the GENI CORE network VLAN 3715.

    193 To define the OF RSpec for the BBN site we need to consider the compute resource used for the site which is the node navis.gpolab.bbn.com and determine how they are connected on the OF switch at the site.
    194 To determine the ports and Data Path IDentifier (DPID) see the [http://groups.geni.net/geni/wiki/GeniAggregate/GpoLabOpenFlow BBN OF Aggregate] diagram and locate where the node is connected. The following diagram show the information from the BBN OF Aggregate diagram that is needed for the BBN !OpenFlow request RSpec:
     193To define the OF RSpec for the BBN site we need to consider the compute resource used for the site which is the node navis.gpolab.bbn.com and determine how it is connected on the OF switch at the site, and then determine how that connection connects to the network core OF VLAN 3715. To determine the ports and Data Path IDentifier (DPID) review the [http://groups.geni.net/geni/wiki/GeniAggregate/GpoLabOpenFlow BBN OF Aggregate] diagram and locate where the node is connected. The following diagram show the information from the BBN OF Aggregate diagram that is needed for the BBN !OpenFlow request RSpec:

    205204The VLAN 1750 is used at every meso-scale site for MyPLC resources to access the back bone OpenFLow VLANs. Also, for the BBN ''habanero'' OF switch *only*, you must add 24 to the physical port number to determine the port to use in the rspec. The host navis.bbn.com is on port 32 (+24=56),  which means your rspec will use  port ''56''  and port 47 (+24=71) maps to ''71'' to get to poblano.  The syntax for each of these can be "borrowed" from the listresources associated to each DPID. 
    206205
    207 Now we have all the information needed to define the OF resource details. These are the RSpec lines that define the ports on habanero:
