When Other Devices Ping Switches, Packet Loss Occurs When the Speed of Ping Is Fast, and Packet Loss Stops When the Running Speed Is Low. Why?

When a device pings a switch, the device and switch exchange ICMP packets. To protect the CPU, the rate of ICMP packets is limited on switches. To set the threshold for the rate of ICMP packets, run the icmp rate-limit command. To restore the default threshold for the rate of ICMP packets, run the undo icmp rate-limit command.

I think you need to see the cpu-defend to check if there is packet loss at the cpu-defend, if there is packets drop at the cpu-defend, you can increase the threshold for the ICMP packets.

if no packets drop at cpu-defend, maybe the packets were drop at other device. you can configure packet statistics to confirm where the ICMP packets were drop.

below command is to check cpu-defend statistics:
