1  –  event_dispatcher

1.1  –  outbound_stream 

    Sets the filters to block the specified events for the entity
    instance or class. It causes the named events to be blocked.

    See the appropriate filter type below for command examples.

1.1.1  –  global_filter 

    block [node node-id] event dispatcher outbound stream simple-name -
        global filter ((class-name[,class-name...]), event-name )

    Global Filter

    Specifies a class name, excluding all instance names
    (for example, node, mop, circuit), and identifies the event to be
    blocked.  To block all events for the class, specify "all" instead
    of an individual event.

    Examples:

    block event dispatcher outbound stream local_stream -
        global filter ((NODE,CSMA-CD,STATION), Unavailable User Buffer)

    block event dispatcher outbound stream local_stream -
        global filter ((NODE,Event Dispatcher), All )

1.1.1.1  –  Exception Messages 

 o  illegal block

    The attempted block operation is illegal; for example, the
    command attempted to block the event dispatcher outbound stream
    events lost or shutdown events.

 o  illegal element

    The command did not include a class-name or instance-name
    argument, or an argument contained one of the following illegal
    elements: wildcard, node name, node class, illegal class.

 o  entity class not supported (OpenVMS)

    The Event Dispatcher is not registered with EMAA.  The NET$EVD
    process is probably not started.  For instructions on how to
    restart the Event Dispatcher, refer to
    HELP NETWORK_MANAGEMENT EVENT_DISPATCHER.

 o  no such object instance

    The specified event dispatcher outbound stream instance does
    not exist.

1.1.2  –  specific_filter 

    block [node node-id] event dispatcher -
        outbound stream simple-name -
        specific filter (instance-name, event-name )

    Specific Filter

    Specifies an entity including instance name, and names the event
    to be blocked.  To block all events for the instance, specify
    "all" instead of an individual event.

    Examples:

    block event dispatcher outbound stream local_stream -
      specific filter (Node LOCAL:.LAMCHP Event Dispatcher -
      Outbound Stream local_stream, Events Lost)

    block event dispatcher outbound stream local_stream -
      specific filter (Node LOCAL:.LAMCHP MOP Circuit CSMACD-1, All)

1.2  –  sink 

    Sets the filters to block the specified events for the entity
    instance or class. It causes the named events to be blocked.

1.2.1  –  global_filter 

    block  [node node-id] event dispatcher sink simple-name -
            global filter ((class-name[,class-name...]), -
            event-name)

    Global Filter

    Specifies a class name, excluding all instance names (for
    example, node, mop, circuit), and identifies the event to be
    blocked.  To block all events for the class, specify "all"
    instead of an individual event.

    Example:

    block event dispatcher sink local_sink -
            global filter ((Node, Event Dispatcher, SINK), All)

1.2.1.1  –  Exception Messages

 o  no such object instance

    The specified event dispatcher sink instance does not exist.

1.2.2  –  specific_filter 

    block  [node node-id] event dispatcher sink simple-name
            specific filter (instance-name, event-name)

    Specific Filter

    Specifies an entity, including instance name, and name the
    event to be blocked.  To block all events for this instance,
    specify "all" instead of an individual event.

    Examples:

    block event dispatcher sink local_sink -
        specific filter (Node LOCAL:.LAMCHP Event Dispatcher -
        Sink local_sink, all)

    block event dispatcher sink local_sink specific filter -
        (Node LOCAL:.LAMCHP Event Dispatcher Sink local_sink -
         Inbound stream EVD$IBS$0000, all)
