(?With the rapid spread of XX Telecom's IPTV services and the ubiquity of attack traffic on the network, the CPU usage of devices such as 7609, 6509, and 4507 as convergence layer switches is usually high. In order to avoid continuous CPU usage If it is too high, the use may be terminated. This solution is specially formulated. Cisco's Hardwarerate-limit and ControlPlanePolicing (CoPP) are used to protect the CPU of the switch accordingly, further improving the service availability and user experience. ?This solution will focus on managing the following three questions: ?1) Why does the attack packet whose destination address is not 7600 also cause the CPU usage of 7600 to be too high? 2) Why is the traffic of the attack packets small, and sometimes only a few tens of megabits per second can cause the CPU to rise to 100%? ?3) What is the management method for this situation?)
