How does the H Series handle ADP?

Options

I have an USG FLEX 100 running at a customer location that logs about 35 ADP alerts per day. I installed a 200H at a different customer location and enabled DoS Prevention w/ the default DOS_PREVENTION_PROFILE. The 200H generates no alerts and if I look at Log/Events, the DoS Prevention log is empty. Both of these locations had Juniper Firewalls previously and both logged numerous port scans and floods per day.

Is ADP working on the 200H?
