Mapping wireless LANS from the wired side

[Mike.Ruscher () CSE-CST GC CA]

This issue may have been discussed earlier but my search failed to find
anything definitive.

When mapping a LAN topology, what are the general methods to use for
discovering access points and  wireless hosts from inside the wired network.
This becomes important to detect rogue WLANS which are a potential threat to
the enterprise as they might be behind firewalls etc.

I would expect that the MAC addresses for APs would be unique to the various
vendors., as would the wireless NICs on the WLAN hosts. Are there any
scanning tools freely available that can do this kind of search?
