Use the option that provides the balance criteria with the greatest variety in your configuration. For example,
if the traffic on an EtherChannel is going only to a single MAC address and you use the destination MAC
address as the basis of port-channel load balancing, the EtherChannel always chooses the same link in that
EtherChannel; using source addresses or IP addresses might result in better load balancing.
