ISTR that some years ago, I did a check and found that ~0.5% of
packets in our corporate network were being leaked into the incorrect
VLAN.  [Though my memory may be going]  I haven't looked recently.

I've also got a switch that believes that VLANs are only related
to IP - it will happily copy DECnet packets to all switch ports
irrespective of VLAN associations.  (And this switch came from
the company that DEC sold their switch business to).
