This error message usually means that the Performance Endpoints cannot ping each other. You need to look closely at this error message to see who reported it, either the IxChariot Console or Performance Endpoint 1. This will help you decide which address is not reachable. Q: Why do IxChariot graphs show lines that are not linear but seem to be wave-like? A: IxChariot, unlike lower layer traffic generators, uses real protocol stacks to generate stateful traffic just like real end-users. One of the indicators of this stateful traffic from a graph perspective is a graph that reflects such characteristics of TCP slow start and dynamic window sizes. Q: How do I configure IxChariot to work in address-translated networks? A: Read the test primer IxChariot Testing in Address-Translated Environments. It explains the key concepts to effectively use IxChariot with devices performing traditional static Network Address Translation (i.e. one-to-one NAT) and static Network Address Port Translation (N
