Note: If you are not familiar with the concepts of the data plane and control plane on network devices, I highly recommend reviewing my Understanding the Data, Control, and Management Planes of Network Devices post prior to reading this post. If you are not familiar with the concept of CoPP (Control Plane Policing) and how it can introduce packet loss for control plane traffic, I highly recommend reviewing my Understanding Control Plane Packet Loss due to CoPP post prior to reading this post.
