    Hi,
    I have configured MC-LAG in Aruba 8320 with Vmware EXSI on HPE DL380. But LACP forwarding mode shows as "LACP-BLOCK"


    interface lag 8 multi-chassis

        description DL380 E9:E9:XX

        no routing

        vlan trunk native 1

        vlan trunk allowed all

        lacp mode active

        lacp rate fast

    Is the LAG configured correctly on the ESX host? Is LACP enabled?

    LACP on VMware vSphere is supported only if you can setup vDS (virtual Distributed Switch). vSS (virtual Standard Switch) implementations support only static aggregations (thus simple static - VSX or non-VSX - LAGs in ArubaOS-CX jargon or type "trunk" Ports Trunks in ArubaOS-Switch jargon).

    Are you playing with vDS or vSS?

    Vmware Standard doesn't support VDS. Is that mean we can't achieve LAGs with VSX. Since VSX uses a separate control plane.

    "Vmware Standard doesn't support VDS"

    Correct.

    "Is that mean we can't achieve LAGs with VSX"

    Not correct: you can terminate a VSX LAG against a vSS but that VSX LAG needs to be "static" (non LACP). VSX LAGs can be LACP/non-LACP.

    That's to say that if you are playing with a quite common VMware vSS implementation then you can deploy LAGs on vSS and you can terminate them against a VSX but those vSS LAGs necessarily (due to vSS restrictions) needs to be "static" (non LACP) and, to match, the same must happen on VSX side (Static VSX LAGs).

    What you call MC-LAG (Multi-Chassis LAG) is called VSX LAG on Aruba VSX current literature. VSX LAGs can be static/LACP even if, normally, you will see more often VSX LAG deployed with LACP other than with "non protocol" (static).
