    162162Step 1. Collect listresources from all FOAM Aggregate.  The manifest RSpec details all resources at the aggregate, but does not provide any insight into whether they are available.
    163 Step 2. Review [http://groups.geni.net/geni/wiki/GeniAggregate GeniAggregate] to determine how each MyPLC host maps to the Site's OpenFlow switch. Determine addresses and ports.
    164 Step 3. Define site specific OF Group rules.
    165 Step 4. Using guidelines from the [http://groups.geni.net/geni/wiki/HowTo/WriteOFv3Rspecs#WritingOpenFlowv3requestrspecs Writing OF V3 RSpec] page merge the information from step 1 and 2 to generate the request RSpecs.
     163Step 2. Review [http://groups.geni.net/geni/wiki/GeniAggregate GeniAggregate] to determine how each MyPLC host maps to the Site's OpenFlow switch. Determine addresses and ports, and define site specific OF Group rules.
     164Step 3. Using guidelines from the [http://groups.geni.net/geni/wiki/HowTo/WriteOFv3Rspecs#WritingOpenFlowv3requestrspecs Writing OF V3 RSpec] page merge the information from step 1 and 2 to generate the request RSpecs.

    167166Each of the above steps is covered in detail below:

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. 
    191 
    192 Let 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.
     189'' ''' 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.  In addition OF groups rules will be defined for each of the site to handle traffic for the hosts.  Each site Rspec will include a group definition that looks as follows:
