Example: Using Packet Trace
This example provides a scenario in which packet trace is used to troubleshoot packet drops for a NAT
configuration on a Cisco ASR 1006 Router. This example shows how you can effectively utilize the level
of detail provided by the Packet-Trace feature to gather information about an issue, isolate the issue, and
then find a solution.
In this scenario, you can detect that there are issues, but are not sure where to start troubleshooting. You
should, therefore, consider accessing the Packet-Trace summary for a number of incoming packets.
