With the BCF test path feature, you can simulate VM-to-VM traffic visibility across the virtual and physical network. On the controller, the test path feature displays both the physical and logical paths that the traffic takes from one VM to another. This level of traffic visibility helps you rapidly determine if an application issue is network-related or compute-related without going through tedious trouble-ticket processes.
The following table shows the various types of VM-to-VM traffic and where they are visible:
