So i have been watching countless videos on how to properly setup my CRS328-4C-20S-4S+ so that it will do hardware offload for the switching. using bridge, and making sure that hw offload flags are everywhere. Also only enabling vlans that are being used. Ingress filtering to not learn mac addresses from switches that are connecting. but as i was driving home i noticed that the cpu would spike from 8% to 49% and right now the network is just in my lab (planning to have a few thousands clients connecting to the network for an event). So im wondering what might be creating these spikes. Could someone maybe guide on how to diagnose this?
Thank you in advance !!
