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?
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.
