By default, Structure View visualizer always uses the predefined “root” protocol when it parses incoming packets. The following table describes default root protocols for each supported source type:
|Default Protocol Name
Each individual Structure View window allows you to select another protocol to become a root for each packet. If monitored packet does not belong to the selected protocol, it is never displayed, thus the root protocol may also behave like a filter.
To change the root protocol, do one of the following:
Before session creation: after you add a Structure View processing module in the Session Configuration Window, open its configuration and switch to the Root Protocol tab.
For running session: click on Structure View's configuration settings in Sessions Tool Window and switch to the Root Protocol tab.
For running session: right-click in the visualizer to bring up the context menu and select the Set Root Protocol… item.
Select the protocol from a list. If you are changing the setting for a running session, use the Affect only new packets switch to control the change behavior.
If you leave the switch unchecked, the session will be paused until the Structure View visualizer finishes updating.
