Device Management : Viewing device summaries : Using list filters
 
Using list filters
You can enable filters to control the information that is displayed by the device list. Filters are useful for reducing the number of entries that are displayed on a list so that you can focus on the information that is important to you.
You add filters to a device list by going to Device Manager in the navigation pane and selecting a device group, then the Filter button in the content pane to display the Device Filter Settings window. From this window, you can select any column name to filter, and configure the filter for that column. You can also add filters for one or more columns at a time.
