I think it would be a great troubleshooting help to have a way to test the various links between Identifi infrastucture equipment.  It would be interesting if we could run iPerf between an AP & Controller, Controller and a Cloud iPerf server and even controller to controller over a WAN link.  In addition it could also use the bricks App to test each of those hops from a client perspective. This would provide actual client throughput validation and testing.  This would help not only customers but GTAC as well in troubleshooting.
