Displaying Object To drill down for more detailed information for an object in the Explore Details view, double-click on the object. All Monitor views, including the Explore

view itself, are updated to display information specifically about the selected object.

For example, if the Explore window is showing link status for a Mobility Domain and you want to display information for a specific WX switch, double-click on the switch.

Displaying 802.11 When a floor view is displayed in the Explore view, you can display Coverage 802.11 coverage for the floor. To display coverage, select MAPs, then

click on one or more of the following icons on the Explore view’s toolbar:

Displays 802.11a coverage.

Displays 802.11b coverage.

Displays 802.11g coverage.

Here is an example of the 802.11g coverage of a MAP radio, displayed according to the baseline association rate of 36 Mbps.
