    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?
