CPU rate-limiting
CPU rate limiting identifies the traffic type and assigns a maximum rate limit to the traffic type. The
traffic types which are subjected to rate limiting include broadcast ARP and other exceptions, such
as TTL exceed, IP MTU failed, reverse path check failed, IP fragments, and unsupported tunneling.
Each of these types is rate-limited individually.
