Hi, list.
I have MX480 with MS-MIC16G (Junos 15.1R6.7).
Now I try test config (see bellow) with policer and NAT (over service-set).
Policer in output direction dosn't work.Customer not limited in output
direction.
On input - policer is working.
I checked that the policer is programmed on fpc:

Question:
1) This is a bug that can be fixed by replacing JunOS.
Will this configuration work on 16.1R7?
2) If this is a feature (policer not work in output direction with
attached service-set (NAT) on interface), then in what way I can
limit my customer?
See my configs below:
