Enabling Alarm Reporting for Packet Loss Caused by CPCAR Exceeding

To protect the CPU, a switch limits the rate of protocol packets sent to the CPU based on the CPCAR. If the rate of protocol packets exceeds the CPCAR, excess protocol packets are dropped. As a result, the corresponding service may not run normally. To quickly detect packet loss caused by CPCAR exceeding, you can enable alarm reporting for this event. After this function is enabled, the switch checks for packet loss caused by CPCAR at 10-minute intervals. If the switch finds that the number of dropped packets of a protocol increases, the switch reports a packet loss alarm.
