Rephrase.

Any managed switch should be able to do that.
A MIkroTik can of course, all with one bridge group.. There are many different 
ways of doing it there.
The SM isolation should be turned on as well.

Only on two different router interfaces.  If they're on a switch, then no.

I think Dennis may be referring to how you should ideally have things 
configured, and I think you're talking specifically about the feature in Canopy 
equipment labeled "SM Isolation".
Ideally, yeah you should make it so one customer can't break everyone.  That's 
a multi-faceted thing and SM Isolation is one component of it.

If you're looking specifically for a router plugged in backwards, add a 
DHCP-client to the interface facing the AP, and (*critical*) uncheck the boxes 
for "add default route" and "add peer DNS".  That might be the kind of quick, 
simple test you're hoping for.

A. we have some locations where we dont use client isolation and B client 
isolation doesnt apply to two access points as far as I know

Your client isolation should take care of that.  FYI.

I wasnt clear, I was actually looking for rogue subnets in general
another issue example is that a customer with some time clocks recently had a 
slick tech put a switch in before the router at multiple locations from the 
same site, different APs, we bridge the APs at the POP, so they were directly 
communicating

If, for example a customer has a router connected backward, is there an 
arp(ish) check aside from packet sniffing to see this since its not a subnet on 
the interface and there wont be an arp entry?
