I'm searching a switch where I can route all ethernet packages over one input/output port. It should be impossible to communicate directly between two ports, but with that single on. How is such a feature, where I can decide which ports are allowed to communicate directly with eachother, called?

  • You are not very clear on what you are asking. Do you mean somethng like Private VLANs?

There are several ways to do this depending on the switch vendor. Here is a list of features that can accomplish what you want to do:

  • Private VLANs
  • EVC: Ethernet Virtual Connection
  • VPC: Virtual Private Connection
  • Bridge ports

The list goes on, but that should be a good starting point to compare switches with.
