How to Use Type of Messages to Filter Events

The filter files are provided as templates, defined without any filtering actions. In decoding mode, the selection conditions must be defined in the specifications of an action in order to be used.

Here is an example of how to define a filter action whilst editing an event file with the Protocol Event Editor:-

  • Open the Event File in the Protocol Event Editor with a reference filter.
  • Select Edit=>Protocol filter from the File Menu to display the Event Filter Editor.
  • In the filter action list, double click None and replace it with Display.
  • The selection conditions can be specified by editing the action.

OSI layer 2 RR frames filtering

Here is an example of how to use a display action and to select all the protocol events which correspond to all types of OSI layer 2 frame (LAPB for example) except RR frames:-

  • Select the action Display (Replace None with Display).
  • Edit the action (Events from Filter set 1 which groups, by default, all the interfaces).
  • Frame normal type deselected (Protocol events - BOP (D:1) Decoding).
  • All frame types selected (TD + RD) except RR frame type deselected (Protocol events - OSI Layer2 (D:2) Decoding).
