Example: Configuring Packet Trace
This example describes how to configure packet trace and display the results. In this example, incoming
packets to Gigabit Ethernet interface 0/0/2 are traced, and FIA-trace data is captured for the first 128
packets. Also, the input packets are copied. The show platform packet-trace packet 0
command
displays the summary data and each feature entry visited during packet processing for packet 0.
