YMMV. I did have to get my account team involved, but from a technical perspective, a one line policer (all UDP rate-limit to 10% of link speed) is not a technical challenge, and the one-off config element is not overly burdensome. Again, YMMV. And, your frequency and impact of IPv4 UDP based attacks will dictate your needs. CB
