Issue/Introduction

Situations exist where connectivity problems occur on a port or range of ports that may be very busy, or have lots of connections / traffic flow, and it is necessary to let a trace run to capture only the handshake from a particular IP.

Is there a way to set up the Smarttrace filter to just record the three-way TCP handshake packets?
