I presume OP is selling 1GE service and protecting that 1GE service so
that NTP DoS can only eat 200Mbps out of it. I.e. you want NTP to hit
both policers, but NTP policer first.

Now another question entirely is, is policer even the right solution
here. Or should there be 1Gbps scheduler with 3 classes of low,
normal, high, and put NTP on low, transport 1Gbps of it, if there is
no demand in normal and high, but yield all of it to normal and high.
