The numbers are based on tests we did on the IronCore hardware. We too wanted to limit CPU utilisation. Connected switches remained usable while the address learning rate was not affected.
But again it are egress limits. Multicast, broadcast and unknown unicast frames hit the CPU before they are dropped or forwarded.
