Description (partial)

With "storm-control unknown-unicast level 1m bps" configured on a physical interface, it was observed that pinging local loopback addresses or other local interfaces sourced from local interfaces resulted in high ICMP packet loss.

Observed on C9606R, running 16.12.1. With "storm-control unknown-unicast level bps 1m" configured on a physical interface (FortyGigabit1/0/1 in this case), pinging local loopback interfaces (sourced locally) results in considerable ICMP packet loss.
