The Software Protocol Analyzer (SWANA) Filters dialog box is used to configure three display filters.

In the SWANA main window, select Tools > Filters.
The SWANA Filters dialog box appears.
The SWANA Filters dialog box contains three tabs that allow a filter to be specified. It also provides help on regular expression syntax.

Display Filter |
If the Regular Expression field is not left blank, only the data that matches the regular expression that is provided will be copied into the display and log file. |
|
Start Trigger |
The Start Trigger is used to disable copying to the connection data text box or log file until an incoming data that matches the regular expression is found. The matched line is included in the connection data text box and, when logging is enabled, is logged. SWANA generates "Waiting for Start Trigger" and "Found Start Trigger" messages so you know why data is not being displayed or why data starts to be displayed again. |
|
Stop |
The Stop Trigger is used to disable copying to the connection data text box and log file after it finds incoming data that matches the regular expression provided. The matched line is included in the connection data text box and log file. SWANA generates "Found Stop Trigger" messages so you know why data is no longer displayed. If a stop trigger exists and a start trigger does not, then SWANA will automatically place the display into the stopped state. |
Note: Except for the case where a Stop trigger exists without a Start trigger, the filters and triggers do not affect the recording state (as determined by the Play, Pause and Stop commands).
