Description (partial)

Symptom:
When span destination port is connected to a switch it will causes certain ports on the N6k switch to  go spanning tree dispute. This happens because the SPAN port does not drop the BPDUs coming from the end switch connected to it and could potentially leak BPDUs causing the dispute. 

We do not support connecting SPAN Destination Ports to a Switch device.
