There seems to be (even among faculty) a gross misunderstanding of Layer-2. Nearly every textbook starts with IP, and talks about it as if we were 20 years in the past.
Understanding all layers and how they can interact stacked within layers is a big issue. Granted, they aren't coming out of school, but I've seen old Sonet/TDM guys trying to figure out transport of Ethernet and it has been a nightmare on dealing with terminology.
It at first started with trying to explain that vlan based switching is not Layer-3. :(
Use your imagination when they finally got into MPLS, which kindly takes the OSI model like a flat piece of paper and wads it up.
