Use the Packet Processing page to select an algorithm for load distribution.

The Packet Processing page

The upper area displays the available SmartNICs and the port numbering. See SmartNICs and Port Speeds.

In the lower area, you can select the algorithm that is be used for load distribution if you have selected a load-distributing libpcap interface or NTAPI stream configuration.

Hash mode Description
Round Robin Packets are distributed using a round-robin method.
2 Tuple The hash key is calculated from the source and destination IP addresses as they appear in the header.
2 Tuple Sorted Similar to 2 Tuple, but sorted before the hash key calculation so that all traffic between two endpoints is distributed to the same libpcap interface.
5 Tuple The hash key is calculated from the source and destination IP addresses as they appear in the header, the source and destination ports, and the protocol.
5 Tuple Sorted Similar to 5 Tuple, but sorted before the hash key calculation so that all traffic between two endpoints is distributed to the same libpcap interface.
