You can display a topology view of your network, including the state and
relationship of devices. You can right-mouse click on a device in the
topology to display the status of that device. The display can include the
wired network, third-party APs, and rogue access points (access points
that are not authorized to operate in your network).
You also can set thresholds for events. If the threshold is crossed, the
