Remember, for DoS Protection Profiles, firewalls with multiple dataplane processors (DPs) distribute connections across DPs. In general, the firewall divides the CPS threshold settings equally across its DPs. For example, if a firewall has five DPs and you set the Alarm Rate to 20,000 CPS, each DP has an Alarm Rate of 4,000 CPS (20,000 / 5 = 4,000), so if the new sessions on a DP exceeds 4,000, it triggers the Alarm Rate threshold for that DP.
