Is there any way to detect the underlying layout physical layout of a VLAN. For instance, to know whether two devices in the same VLAN are connected via the same wifi AP.
To clarify, this would be from the perspective of a device connected to the WLC, with no special privileges. If you can operate in monitor mode then of course the underlying structure can be seen from beacons/probes etc, but assuming these are not available to you, as on many devices they aren't, I was wondering if anything could be done 'actively'.
The ping time and % packet loss is an obvious option, but I think there's too much variance in both to give a reliable answer. I suspect the answer is no, unless you have admin access to the switch via SNMP. I just want to check there isn't something clever that could be done with LLDP, DHCP or ARP etc.
