when you enable two ports as protected,
those two ports cannot communicate at all.
( not unicast, broadcast, multicast )
But for unknown destination mac addresses, switch
by default will flood to all ports.
This way some packets from one protected port can
go to the other.
If you do not want this behavior, you need to configure
switchport block unicast | multicast
Thanks
