    Product: DCX + FC8--32

    Version: v7.2.0d

     

    The port 11 / 4-7 of the DCX FC8-32 blade shows a buffer limit, and the port 11 / 16-20 is configured with a long distance mode LS 120KM.

    I don't know why this happens. I still see that 102 buffers are still unused. What will happen to this situation?

    "Needed buffers" for ports 4,5,6,7 - 26x4=104, and Remaining Buffers=102. This is a reason of message "Buffer limited" for thous ports, I think so.
