    Hi Guys,

    We were only trying to connect an Aruba controller to the Aruba core switch(2930F)? what could have cause a loop? ?
    Aruba Core switch is connected to a number of cisco access switches via LACP.
    Aruba controller is also connected to Aruba coreswitch using a single LAN cable.
    Access switch ports are both configured in interfaces of Aruba Controller and Core switch where the controller is connected.
    Loop protect is enabled on switchport where the Aruba Controller is connected to the core switch.
    Attach is the core switch configuration. Really appreciate if you can point out the root cause and if added switch configs are needed to prevent this issue from happening again.

    Thanks,
    G

    Normally loop protection is used for downlinks to edge clients and on links to unmanaged switches as alternative of STP. Loop Protection on uplinks can cause issues and undesired behavior.

    This is mentioned for sure somewhere in the guides where loop protection is described.

    Try to adjust your configuration and see if the issue is gone after connecting the controller again.
