So what do you do in times like that when you feel your hands are tied? If you are on a Cisco router, you may want to use the debug ip packet IOS Command but then you have probably heard (and experienced?) that turning on debugging on a production network can have serious performance impacts. Have you ever been in a difficult position as a Network Engineer where you keep troubleshooting a problem but you are not making headway? In certain instances like that, you just wish you can see what is really happening with each packet in the traffic flow.
