By default it using src-mac for load-balancing. Most of the time the traffic is local to the same switch and subnet from the server to the clients I’m thinking src-dst-mac would be a better load-balance method? The switch is a 3850 with IOS-XE 16.3.6. Is there a way to test the algorithm like the 3750’s test etherchannel load-balance? I did look at the ports themselves and one has more traffic but that all depends on the usage by the users as well.
