the packets from being routed to the CPU at an undesired rate that might impact the performance of a switch
and the network. In addition, the CoPP protects the CPU from denial of service (DoS) attacks and ensures
routing stability, reachability, and packet delivery. You can use Multi-Layer Switching QoS CLI to set the
rate limit and policing parameters on a specific protocol.
CoPP is supported only on LAN BASE, IP Lite, and IP Service licenses.Note
