Performing a communications trace

You can use CL commands in the character-based interface to perform a communications trace. If you want to start a new trace on the same line, first delete the existing communications trace.

1. Starting a communications trace
   This action starts a communications trace for the specified line or network interface description.
2. Ending a communications trace
   To format and display the trace, first end the trace. This action ends the trace but saves the data in the communications trace buffer.
3. Dumping a communications trace
   Dumping the data to a stream file offers several advantages. Consider these advantages when deciding whether to use this function.
4. Printing a communications trace
   For IPv4, you can print a communications trace from the raw data you collected, or you can print from a stream file in which you previously dumped the raw data. For IPv6, you can only print from a stream file.
5. Viewing the contents of a communications trace
   To view the contents of a communications trace, follow these steps.
6. Reading a communications trace
   The communications trace displays several types of information.
7. Deleting a communications trace
   You must delete a communications trace before starting a new trace on the same line. The communications trace can be deleted after the trace has ended. This action deletes the communications trace buffer for the specified line or network interface description.
