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 affected device is flagged, and a star is placed beside the parameter that triggered the threshold.
