  In this paper, we present a tool which allows capturing Channel Access (CA) traffic directly off the network and interpreting the contents with a graphical or textual user interface. The tool is the widely used Wireshark (former Ethereal) network capture and analysis application, for which we have implemented a plugin that parses (dissects) contents of CA network packets. The tool is freely and openly available for several operating systems, and we have built and tested the CA plugin for Windows, Linux and Darwin (Mac OS X). We first describe the Wireshark framework, followed by the steps needed to implement a dissector plugin. Then, we present the features and limitations of our CA dissector implementation. Afterwards, we explain how to install and use the Wireshark application and the CA dissector. Finally, we present some examples where we have found the tool to be useful.
