CONFIGURATION OF FILTER FOR DATA STREAM ORGANIZED IN FRAMES

A method of configuring a filter for a data stream organized in frames in a protocol tester that is simple without requiring any knowledge of an internal protocol configuration provides the frames partially decoded in an overview display. A user searches the frames for a desired content and selects one of the frames having the desired content. The selected frame is displayed in a fully decoded view. A filter rule is derived from the desired content for configuring the filter. The filter rule may be further defined by modifying parameters from the fully decoded view of the selected frame. The configured filter is applied to all the frames to produce a set of filtered frames.
