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. 

RF monitoring provides you with current and historical information about 
your radio health and activity. Data collected for the RF environment and

This information can be viewed as a list of radios heard by a particular 
radio, as well as a list of radios who can hear a particular radio.
