Hi!

I don't think it can work, because a port not isolated, have access to
all other ports,including isolated ports.
"
isolated on or isolated off
Controls whether a given port will be isolated, which means it will be
able to communicate with non-isolated ports only. By default this flag
is off."
for example:
vm1: isolated
vm2: isolated
vm3: non isolated
vm1: can't access to vm2
vm2: can't access to vm1
vm3 have access to vm1 && vm2 isolated. (but user is thinking that vm1
&& vm2 are secure).
and vm1/vm2 have access to vm3 too.
That's why I have done it at bridge/vnet level, all or nothing.
The main usage is to have only 1 upstream port non isolated (traffic
coming from outside)
>>Also I think 'Isolate Ports' or 'Port Isolation' would be the better
>>label, 'Ports Isolation' sounds a bit wrong to me.
I'll send a v2 with "Port Isolation"
Otherwise, consider this:
