Protocol Directory – Create New
For example, let’s say that you have a custom accounting application that uses TCP as a transport layer
protocol, using TCP port number 50161. All you need to do is create a new protocol, identify its TCP port
number, and define the statistics you want to collect. To do this, select Setup > Protocol Directory and click
Create in the dialog box displaying the list of protocols the NAM is currently monitoring for. A dialog box will
appear that allows you to choose the protocol that your proprietary protocol is encapsulated within. In our
example, it is TCP. Click the radio button for TCP and click the Next button. This brings you to the second
step of the create new protocol wizard that prompts you for, the TCP port number, the name you want to
assign to this new protocol (that will appear in the Protocol Directory list illustrated above), and what statistics
you want to gather for this new protocol. If this application actually used a range of continuous ports, you can
also select the number of port to include after the entered TCP port. The end result is that the Traffic Analyzer
will be able to differentiate this proprietary application by its TCP port(s) assignment and represent the
application in the graphs and charts that provide application layer information.
