The new 1.8.5 vlan (p)vid features are great for switch usage, however before being a perfect replacement (in my opinion) for the mikrotik RG260GSP, I would like to know if UBNT will put a port isolation or even a forwarding table in the switch config? Or is there already a undocumented CLI command to do this?
The port isolation feature will only let member interfaces of the switch group communicate with the router, but not with eachother, therefor you can share the same subnet/interface on the router.
The forwaring table will give you much more advanced control by not only allowing traffic to the router(isolation only), but will also let some hosts on some ports communicate with eachother well blocking other hosts on other ports while being on the same subnet.
