This video tutorial by Cisco's TAC team demonstrates how to perform packet replay using Cisco Firewall Management Center (FMC) version 7.6, including steps for both manual input and pcap file methods.
MAIN POINTS FROM TRANSCRIPT
- Log into FMC and navigate to Devices > Troubleshoot > Packet Racer.
- Input source and destination IP, port, protocol, and select Ingress interface for packet replay.
- Optionally, simulate packet transmission from the device using the "allow simulated packet" option.
- Upload a pcap file to autofill details and view trace results for individual packets.
TAKEAWAYS
- Packet replay can be performed manually or using a pcap file in Cisco FMC.
- Access control policies determine whether specific traffic is allowed during packet replay.
- The "allow simulated packet" option enables actual packet transmission from the device.
- Trace results provide detailed insights into packet handling and policy application.
