I recently installed the DGS1210-28 smart switch and since then I am unable to view the network map in windows 7.   Normally, I am able to just go to network settings and press the "See full map" and it would show all connected devices.  
  I have read that one cause could be LLDP is not enabled.  The problem is that I do not see any such setting in the switch menus.
  I am really confused with this and seemingly unable to do usual searches for anybody with the similar problem.
  Any help with this would be greatly appreciated.  Thank you.
