Filter editor: Protocol conditions

Selecting conditions. Messages of certain types, events including some field values. See features.
Counting specifications. Messages of certain types, events including some field values. Data flow measure... See features.


PH events

Reminder of the physical interface type and the selecting conditions can be defined according to different modes :

  • Decoding. To choose the selecting conditions in the list of the possible event types, depending on the interface type.
  • Service. Not used.
  • Value. Selecting conditions can be defined by value(s).


SL events (or DL events)

Reminder of the protocol stack . Reminder of the SL protocol stack, with (D:i) the layer of appliance mentioned  for each used protocol. The highlighted protocol is the current one with the following display rules:

  • Protocol (D:i). Not any selecting condition is defined.
  • >> Protocol (D:i). There is at least a selecting condition defined according to the modes with a mark displayed in the attached box.
    The combinations of >> and marks are useful to have a glance to the different event selecting conditions implemented.

Selecting conditions can be defined according to different modes :

  • Decoding. To choose the selecting conditions in the list of protocol unit types, depending on the protocol layer in use.
  • Service. Only for protocol filter use.
    To choose the selecting conditions in the list of the service primitive types, depending on the protocol layer emulated by Clarinet.
  • Value. Selecting conditions can be defined by value(s):
    • a field value in a control field identified in all the types of the messages of the protocol layer.
    • a data value identified in the data field of the messages of the protocol layer, conveying data.

For statistics use, the Decoding / Multiplex recording mode MUST be set.

  • Measure. Only for statistics filter use.
    To edit specifications for data flow measure or counting number of frames with a certain length.
OR/AND operator. The logical Or operator by default between Decoding (or Measure) and Value modes can be replaced by the logical AND operator, if both modes are in use.
