I just noticed, you put agg before the ntp term, which would be bad
because 800Mbit/s of NTP would first steal these from the 1g policer
and after that get policed to 200m if I'm not mistaken?

So I think the correct order would be:

term ntp
   from ntp
   then policer 200m
   then next-term
term agg
   then policer 1g
   then accept
