  DECnet-Plus PDU Discard messages? 
 The Question is:
 
Just recently, we upgraded our VAX systems to OpenVMS 7.1/DECnet Plus from
 OpenVMS 6.1/DECnet Phase IV. After upgrading we have seen numerous message
on
 the console terminal which is similar to this:
 
 %%%%%%%%%%%  OPCOM  29-DEC-1998 18:44:01.77  %%%%%%%%%%%
 Message from user SYSTEM on CVCOM1
 Event: Address Unreachable PDU Discard from: Node LOCAL:.CVCOM1 Routing,
         at: 1998-12-30-02:44:01.740+08:00Iinf
         Discard Reason=Destination Addrs Unknown,
         Source Address=47:68:00-2B:AA-00-04-00-08-AC:20,
         Forwarding Address=47:68:00-2B:AA-00-04-00-04-AC:20
         eventUid   7214D8C0-9F4E-11D2-B866-08002B973004
         entityUid  85F782C0-8F72-11D2-8003-AA00040002AC
         streamUid  8C8780E0-8F72-11D2-8006-AA00040002AC
 
 What causes this problem and its solution? If not, is there a way to filter
out
 these kind of messages from appearing in the console terminal?
 
 Thanks,
 Roose
 
 
 
 
 The Answer is:
 
  To block the message, place the following line:
 
    BLOCK EVENT DISPATCHER OUTBOUND STREAM local_stream GLOBAL FILTER -
            ((NODE,CSMA-CD,STATION), Address Unreachable PDU Discard)
 
  in the file:
 
    SYS$COMMON:[SYSMGR]:NET$EVENT_LOCAL.NCL
 
  Then please contact the Compaq Customer Support Center, as this will
  likely take some investigation to resolve the underlying problem, the
  problem that is triggering the error.  (It may be something as simple
  as an application on node 43.8 that is polling node 43.4, and 43.4 is
  a node which has not yet been seen by the routing node CVCOM1.  Again,
  some additional investigation appears warranted.)
