Using IP packet trace

The IP packet trace facility is used to trace the flow of IP packets. It is useful when tracking the cause of packet loss or corruption. If the LINKNAME parameter of the IP packet trace facility is specified, only packets that are transferred along the specific link are traced. Specifying this parameter is recommended to avoid tracing many unrelated packets. See TCP/IP services traces and IPCS support for details about how to use the IP packet trace facility.
