The traffic module might be your friend here. Saying :
tcptrace -xtraffic file.dmp
where file.dmp is your dumpfile, should leave a file called
traffic_byport.dat in your working directory having basic port-wise
statistics. You may also give stuff like :
tcptrace -xtraffic"-p22,25,80" file.dmp
to get you statistics on ports 22(SSH), 25(SMTP), 80(Web) only.
(I am making out a manual for tcptrace which documents stuff like this in
much more detail. It should be out in a week.)

You can filter out connections with the -f option as in :
tcptrace "-f port==80" file.dmp
to get you details of the http connections traced by tcptrace, and also
leave a file PF in the working directory having the connection numbers of
the http connections.
You may pull out those connections alone into a small file say, web.dmp
using something like :
tcptrace -oPF -Oweb.dmp file.dmp
Once again, the manual would hopefully answer your questions better soon.
