what i run in to is when i scan a switch and a computer is off it will remove the entry. from the switch when in some cases i was only looking to match one port but which it does but it deletes 3 others.
Switch pages only list assets connected to the switch at the time of the last scan. Lansweeper does not currently keep a history of this information. This feature is on our customer wish list, but we do not yet have a release date for it.
