Info

EARLY FIELD TRIAL Chapter 9 224 Sniffer Adaptive Application Analyzer The Expert also provides concise explanations for each symptom and diagnosis generated. To display a detailed explanation of a symptom or diagnosis, click the question mark (?) to the right of the symptom/ diagnosis description in the Expert Detail pane. (You may have to scroll to the right of the pane to see the ?.) Postcapture Expert/Decode Statistics and CRCs Postcapture Decode and Expert statistics for raw packets do not take into account the CRC bytes attached to frames. This is by design, as the CRC bytes are not a part of the frame. Because of this, the Expert will show average frame sizes that are smaller than those reported by other views that do include the CRC – for example, the Statistics tab in the postcapture display, and all displays in the Quick Select window. For Ethernet, the difference will be 4 bytes; for WAN PPP, either 2 or 4 bytes, depending on how the network implements the CRC field. Extra Characters in Expert Displays for High Counts? Occasionally, you may see counts in the Expert displays followed by the letters M, G, or T. These letters stand for Million, Giga, and Tera, respectively. Saving Expert Objects with Trace Files During capture, the Expert creates Expert objects based on the frames it sees. Over a long capture, some of the frames which the Expert used to create these objects will most likely pass out of the capture buffer to make room for new ones. However, the Expert objects themselves will still be in the database. You can make sure that all the Expert objects created during a capture session are saved along with your trace file by enabling the Save Expert Objects checkbox in the Save As dialog box. When this option is enabled, all of the Expert objects in the database are written to the end of the saved trace file. Then, when you open a trace with saved Expert objects, make sure to enable the Load Expert Objects checkbox in the Open dialog box. This way, when you reopen a saved trace file, you can make sure you see all the Expert objects created during a capture session instead of just the ones the Expert creates based on the frames still in the file. Notes on the Save/Load Expert Objects Feature If you enable the Load Expert Objects option when opening a trace file that has no saved Expert objects, no error will occur. The saved file will simply be loaded normally.
