[Nottingham] A strange network switch: Does a 'concentrator'/'mux' network switch exist? - "port isolation"

[Martin]

Aaron,

Thanks for that. The "port isolation" is exactly what is needed, albeit
without the complete flexibility of the TP-Link example for my case.

So... A "managed switch" with that feature is needed or... Are there any
devices already 'hard wired'?...

I'd guess we have super-flexible managed switches such that there would
not be any need for the much lower volume hard-wired 'specialist' stuff.


Thanks, a good solution with quite a few console clicks...

But easier than a gazillion VLANs!


Cheers,
Martin
