ICMP load balancing

You can use the following option to configure load balancing for ICMP sessions:

config load-balance setting

set dp-icmp-distribution-method {to-master | src-ip | dst-ip | src-dst-ip | derived}

end

The default setting is to-master and all ICMP traffic is sent to the primary (master) FPM.

If you want to load balance ICMP sessions to multiple FPMs, you can select one of the other options. You can load balance ICMP sessions by source IP address, by destination IP address, or by source and destination IP address.

You an also select derived to load balance ICMP sessions using the dp-load-distribution-method setting. Since port-based ICMP load balancing is not possible, if dp-load-distribution-method is set to a load balancing method that includes ports, ICMP load balancing will use the equivalent load balancing method that does not include ports. For example, if dp-load-distribution-method is set to the src-dst-ip-sport-dport (the default) then ICMP load balancing will use src-dst-ip load balancing.
