A VLAN will stop a device on one port talking to a device on another
port using a plain switch will not!

Actually it will.

No it won't!
Just download an IP address scanner app and it will find everything
(using IP) on any port.

Dennis. PLEASES read up about how a switch works, and why we HAVE
switches instead of repeaters. And why the little blinken lights on your
switch do not all blink at the same time but in pairs, because packets
are not on all segments simultaneously.

For heavens sake admit you are wrong.
Switches are layer 2 devices and are transparent so everything is
visible whatever you claim.
Vlan switches are not as transparent.

I can assure you that you can ping every device connected to a switch
just as though they were connected to the same segment of ethernet.


And just because its perfectly possible to send a broadcast and get a
response back from every ethernet devices on a given network, doesnt
means that all those devices receive traffic OTHER than broadcasts on a
routine basiss.

How does that equate with your claim a switch will stop things talking
to each other?



On a VLAN it won't.

VLAN is a security issue. It is not about traffic.

So first of all, you need to understand the basics

Go away and stop pretending you know anything new.

Snip cr@p that you can get out of google in three seconds.
