This attribute holds the foreground scanning status. Writing scanning(2) in idle state triggers a new foreground scan cycle. All entries for this client interface in the wlanScanResultsTable are removed. When the WLAN client has finished scanning, the attribute changes back to idle(1), and the wlanScanResultsTable is updated automatically. To update wlanScanResultsTable without triggering a new foreground scan, you can write update(3) to this attribute. This causes wlanScanResultsTable to be updated immedieately, reflecting any changes detected by automatic backgound scanning. After wlanScanResultsTable is updated, the value switches back to state idle(1). Any attempt to write different values, or to write values in a state different from idle(1), is ignored.
