I have a very odd situation that is not something I would expect to see in a production environment. This is purely a test lab.
Is there a way to make a Cisco switch (preferably a 3850) act like it has a switch within a switch? I need to have duplicate VLANs on the same switch and not have them talk to each other.
Example:
Ports 1 - 3 are in VLAN 10 and communicate with each other.
Ports 4 - 6 are in VLAN 10 and communicate with each other.
But ports 1-3 cant communicate with ports 4-6 because they are in separate instances of VLAN 10. These separate instances will need to run their own Spanning Tree because ports 1 & 4 will be bridged between each other through my device under test so that devices on ports 2&3 can see devices on port 4&5
In a perfect world I would just use two switches running vlan 10 and my device under test would bridge the two. Problem is I have to run this scenario on multiple devices under test at the same time so for example 5 tests would require 10 switches.
