I have a current design that looks like this.
Several access switches connect to many booths throughout the office. This office is used for shows and customers plug in their devices into the available slots in the booths. But the problem I am having is that loops can easily occur and vlans being exchanged with new devices, because too often ppl bring their own switches and plug into the available ports. How do i stop this from happening. Sometimes 2 or 3 different customers use the same booth so I cannot do a mac adres sticky. I also want to keep broadcasts to minimum, they are killing the network. What is your advise?
