Debug switch forwarding and dropping frames

AK0

Level 1

Is there a debug command available on a switch that lets me see the frames being forwarded and dropped?

I am testing some scenarios and I want to be notified when a switch receives a frame on a trunk link from a VLAN that is not configured on that switch, so the frame is dropped.
