Error description

  • Three different counters are involved in monitor PDUSDISC
    (PDU's Discarded, Unrecognized PDU's and Misaddressed Frames
    Received).  However, NPM was only using the PDU's Discarded
    when testing to see if the monitor value has exceeded the HIGH
    threshold.  In this customer's case, PDUSDISC=(0,3) was coded.
    Panel FNM02RVM would show 15 under heading Total PDU's
    Discarded, but MSGFNM200I was never issued saying the resource
    had exceeded the threshold of 3. It is possible the value of 15
    was distributed on the three different counters as follows:
    PDUs Discarded               = 2
    Misaddressed frames received = 8
    Unrecognized PDUs            = 5
      So, MSGFNM200I would not be issued since PDU's Discarded is
    less than 3.

    PDUSDISC MONITOR IS NOT GENERATING AN ALERT WHEN THE VALUE
    EXCEEDS THRESHOLD. THE PDUSDISC COUNTER WAS WRONGLY CONSIDERED
    AS ONLY THE NUMBER OF PDUS DISCARDED. MISADDRESSED FRAMES
    RECEIVED AND UNRECOGNIZED PDUS WAS WRONGLY EXCLUDED.
