Unknown Devices
Click the drop-down menu under Show and click on Unknown Devices. AirDefense displays a list of all
Unknown Devices seen in your network. Unknown devices are defined from the source or destination
address detected in communication to or from a wireless device. AirDefense can identify the wireless
device the frame is sent from or received by, but if the MAC address listed as the ultimate source or
destination is not a device identified by AirDefense, it is considered 'unknown'. These are almost always
infrastructure devices on the wired network.
The list of Unknown Devices are displayed in a tabular format using a combination of the following
columns:
