You can learn about capture filter syntax here
http://wiki.wireshark.org/CaptureFilters
this is where you set the capture filter. Click Capture from the
menu bar, Options (or one of the pretty icons)

I
am using the most current version of Wireshark. I’m a student at
the University of San Francisco and have an assignment due today that requires
me to change options so that only packets I send are recorded. However,
when I go into options, I do not see where this is possible. Can you
please advise how to change options to capture only sent packets? Tx.
Set up a Capture Filter of that kind.
