Etherchannel question?

DCDDCD Member Posts: 473 ■■■■□□□□□□

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.

Server=(Nic Teaming)=>Switch>Client1,2,3,4,ect

    The load-balacing based in mac are generally bad options.

    The best load-balacing is IP-based, por example:

    dst-ip—Load distribution is based on the destination-host IP address.
    src-dst-ip—Load distribution is based on the source-and-destination host-IP address.
    src-ip—Load distribution is based on the source-host IP address.

    For Server to users trafic, the best option is src-dst-ip.

    Thanks, that was a weird situation I found the port’s flapping and no Etherchannel configured. The vender paperwork said the server was setup for LACP which it wasn’t it was set for on. The bad thing is I don’t know if the performance stayed the same or improved.
