I need to police ingress traffic on a layer2 ("switchport") interface.
Traffic is raw ethernet, so only L2 policying is usable.

Already read config guides, but it takes a while to understand all concepts.
Any sample config, to make me understand better the concepts?
Yep - but I suggest you review the numbers:-
50000000 - 50 megabits per second
1562500 - 1.4 megabits per second
The burst size should be x 2 the CIR - otherwise you will never reach the CIR and you will experiance TCP global synchronization.
