    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)

Right - yes sorry it had escaped me that F5 do not use module 0 for 'real' interfaces and that therefore 0.3 must be something internal used for communication between the motherboard and the switchboard.

 

If you don't have support then try using iHealth, only other option is to reboot the whole thing and pray....
