Frame Viewer When a frame is unable to reach its destination due to timeout, it is discarded. You can use Frame Viewer to find out the flows that contained the dropped frames, which can help you determine which applications might be impacted. Using Frame Viewer, you can see exactly what time the frames were dropped. (Timestamps are accurate to within one second.) Additionally, this assists in the debug process. You can view and filter up to 20 discarded frames per chip per second for 1200 seconds using a number of fields with the framelog command.
