1578 Interfacing Simulations with Live Devices and Traffic Using OPNET's System-in-the-LoopDebugging in System-in-the-Loop• There are several tools available for debugging a SITL simulation• Discrete Event Simulation Log• Check for messages from simulated nodes• Example: OSPF Efficiency being turned on or off• SITL gateway generates log messages on unsupported packet types• Statistics• If packets are going through a simulation, use statistics on intermediatesimulation nodes to ensure packets are flowing through those nodes• SITL provides its own set of statistics• OPNET debugger• Tracing the route of packets• “ltrace sitl”• Wireshark• See all packets coming into and out of the physical interfaces used by SITLCONFIDENTIAL ─ RESTRICTED ACCESS: This information may not be disclosed, copied, or transmitted in any format without the prior written consent of OPNET Technologies, Inc. © 2010 OPNET Technologies, Inc.28
