An interesting thing is occuring here. We have about 30 switches attached into a Pair of Nexus 3172 switches running Nexus Data Broker with a Ubuntu controller. Out of the 30 switches we have connected, Data Broker has decided to add two switches randomly to the topology. Previously we had an issue with unrelated ARP packets causing devices to be added to the topology, but we've since fixed that. Does anyone know why a switch would be added to the topology when it's not running the Data Broker software?
