I wish cheap serial-port managed switches were a thing.
The reasonably cheap managed switches often expose the management interface on all ports, even all VLANs (with no way turn it off).
It’s frustrating that this is just a software limitation - the hardware is damn capable of much more.
Hell, I’d love to have a switch where the management interface was an I2C port that I could plug into just for reprogramming.
Really just want dumb VLANs, no fancy RSTP or such.
