It’s a little more complicated than that. A switch’s main cpu is like a host with rx coalesce set to 100. And there are a surprising number of things that trigger the main cpu beyond management functions. Multicast is a good example. The amount of load on the main cpu can be quite variable, and given ICMP’s low priority, it’s not unusual to see a switch that responds in 1ms suddenly jump to 25-100ms and then drop back.
