Freescale QorIQ networking devices employ complex packet processing engines, capable of protocol header processing, traffic shaping, prioritization and forwarding without CPU intervention. The offloading capabilities are boosting the performance in traffic forwarding and termination scenarios. Adding also a very large and flexible feature set, the offloading technologies require complex hardware initialization sequences and complex run-time programming techniques.This seminar presents the troubleshooting workflow, the tools and techniques, the counters and other tips that make networking issues investigation easier on both QorIQ eTSEC and DPAA platforms. The main scenarios covered include no connectivity, partial packet loss or performance loss (due to imbalanced CPU processing, kernel upgrades or firmware upgrades).
