28.7 One-Way Trace TCP Trace Dynamics

TCP packets generated by FullTcp and passing over a traced link contain additional information not displayed by default using the regular trace object. By enabling the flag show_tcphdr_ on the trace object (see section refsec:traceformat), 3 additional header fields are written to the trace file: ack number, tcp-specific flags, and header length.
