    752752== 32. Get switch statistics and flowtable entries for slivers from the OpenFlow switch. ==
    753 
    754 The head node runs the !FlowVisor for the !OpenFlow switch in the ExoGENI rack. To get access to switch and slice statistics login access to the head node in the ExoGENI rack is required, this is not normally available to experimenters.
     753Statistics can be collected by experimenters and by administrator. In this step verified that both are possible.

     756
     757In this scenario the !FloodLight Controller is used to capture statistics. The Floodlight controller was configured to run on port 33020, in place of NOX.

     799The head node runs the !FlowVisor for the !OpenFlow switch in the ExoGENI rack. To get access to switch and slice statistics login access to the head node in the ExoGENI rack is required, this is not normally available to experimenters. This scenarios was using NOX as a controller for the slice EG-EXP-6-exp3.

     900In this scenario the !FloodLight Controller is used to capture topology information. The Floodlight controller was configured to run on port 33020, in place of NOX. First we list all devices tracked by the !FloodLight controller:
