    Hi Folks!

    Any body using Junos 17.3R2.10 on ACX (2200)s?

    It seems, since upgrading, that all our LAG bundles are only using a single interface in the bundle causing capacity issues...

    I've configured the hashing in forwarding-options, but it made no difference.

    Anybody else seen this? Anybody else got any ideas?

    Thanks in advance for any trouble taken...!

    In case anybody else here via google in the future...

    Turns out there is no default hash-key algorithm setting for the LAG.

    You must explicitly

    set forwarding-options hash-key family inet layer-3
    set forwarding-options hash-key family multiservice source-mac
    set forwarding-options hash-key family multiservice destination-mac

    Then, and only then, layer 2 and layer 3 traffic will be load balanced across all physical links in the bundle...
