Trace of a specific tcp

Greg_F

Hi All,

I have a path with hundred of targets. Along the path I used TCP_a , then later I repass on the same section with TCP_b.
Using the TCP trace, I would like to see continuously the trace of tcp_a for example.
It looks like that the trace switch to tcp_b as soon as the rapid program is using tcp_b, which makes sense. 
But I need to visualize TCP_a while it runs the path with tcp_b.

Any I idea how to do that? 

I hope my description was clear...
