The hashing algorithm used to distribute traffic load among the physical ports of the trunk
while preserving the per-flow packet order. The hashing algorithm uses various packet
attributes to determine the outgoing physical port.The following sets of packet attributes can
be used to compute the hashing algorithm:
Source MAC, VLAN, EtherType, Incoming Port
Destination MAC, VLAN, EtherType, Incoming Port
Source/Destination MAC, VLAN, EtherType, Incoming Port. This is the default selection.
