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.
