It allows you to generate a diagnostic log of system activity over a period of time, and then to download
the log so that it can be sent to your Cisco customer support representative.

To use this tool:

1. Go to the

Diagnostic logging

page.

2. Optional. Set the logging levels:

a. Network log level: the log level for call signaling messages.

b. Interworking log level: the log level for SIP/H.323 interworked call diagnostics.

c. B2BUA log level: the log level for calls passing through the

B2BUA

You should only change these log levels on the advice of Cisco customer support.

These settings affect the amount of logging information that is included in the diagnostic log.

3. Click Start new log.

4. Optional. Enter some Marker text and click Add marker.

The marker facility can be used to add comment text to the log file before certain activities are
performed. This helps to subsequently identify the relevant sections in the downloaded diagnostic
log file.

You can add as many markers as required, at any time while the diagnostic logging is in progress.
You can also supply marker text when starting or stopping the log file.

Marker text is added to the log with a "DEBUG_MARKER" tag.

5. Reproduce the system issue you want to trace in the diagnostic log.

6. Click Stop logging.

7. Click Download log to save the diagnostic log to your local file system. You are prompted to save the

file (the exact wording depends on your browser).

8. Send the downloaded diagnostic log file to your Cisco support representative, if you have been

requested to do so.
