    It's either a problem with;-

     

    • the BigIP switch port
    • the adjacent device port (the port connected to the BigIP port)
    • faulty/loose cable/connection

    Make a visual inspection of cable and check logs on adjacent device. If all OK start moving stuff (one thing at a time) until you identify problem.

     

    • change cable
    • move the cable in BigIP to a new port on the adjacent device (making sure all is configured on adjacent device new port)
    • move cable in siwthcport to new BigIP port (making sure all is configured on BigIP new port)
