    107 Note: Each of the omni command used the -o argument to get the listresources output to a file.  Each of the listresources output files are attached to this page.

     105}}}
     106
     107Each of the omni command above used the -o argument to get the listresources output to a file, all output files are attached to this page as a reference.  The Advertisement RSpec generated by the listresources are then reviewed to generate the Requests RSpecs to reserve the resources. Information in these files provides the switch and the port URN information to be used in making the OF flowspace reservation.

     109The above results will give you some insight into what is available, but it is recommended that you coordinate with the site contact to ensure RSpec accuracy for each of the OF Aggregate Managers.

     114The section shows the compute resources RSpec defined based on the output of the listresources commands.

    139178The OF RSpecs are used to request resources at each site's !OpenFlow Aggregate Manager.  This will result in your resource request being imported into the Opt-In manager, where an Administrator must approve your request for resources. Currently requesting OF resources for the sites in the experiment does not require OF setup for the Network Core path; the default handling will allow OF traffic.  This is expected to change.
