Compare the outbound and inbound packet information. Click on the colored PDU Info box to display the PDU Information window.Ĭ. Locate the first occurrence of Router0 in the Event List.ī. Use the Auto Capture / Play button in the Simulation Panel window to animate the event.Ī. The ICMP filter should be the only box that is checked. Use the Event List Filter in the Simulation Panel to view only ICMP packets. This will identify both the source and destination PCs for the PDU. After clicking on Add Simple PDU, click on PC0 and then PC1. This is the closed envelope located on the right side of the screen. The tab is located behind the Realtime tab in the lower right hand corner of Packet Tracer.Ĭlick on Add Simple PDU. Open the “CCNA2_Concept_Activity_ICMP.pka” and follow the Instructions, which are repeated here:Įnter simulation mode by clicking on the Simulation tab.
