On Network Identifies how AirDefense obtained the MAC address of a non-
wireless device. The dierent entries are:
Sensor SegmentThe frame containing MAC address was
detected by a sensor on its wired port. This device is therefore
known to be on a LAN segment containing the sensor and is
therefore on the same wired infrastructure.
SwitchThis MAC address was obtained from a data poll of the
tables of a wireless switch. At some time, a know wireless device
communicated with this unknown device. The unknown device
is on the infrastructure somewhere, but the LAN segment is
unknown.
BlankThis MAC address was detected by a sensor radio and the
wireless device communicating with this MAC is not sanctioned
in AirDefense. This is most likely a device on a neighboring
network and not part of the AirDefense protected infrastructure.
Sanctioned BSSThis MAC address has been seen by a sensor in
communication with a Sanctioned BSS and is likely to be a
device on the AirDefense protected infrastructure, but has not
been reported to AirDefense as being on the wired network by
poll or discovery.
Classification Displays how the Unknown Device is classified.
