Best Practices for Troubleshooting

Before you make changes to try to fix a problem, generate a troubleshooting file to capture the original problem. See Health Monitor Reports for Troubleshooting and its subsections.

You may need this troubleshooting file if you need to contact Cisco TAC for support.

Start your investigation by looking at error and warning messages in the Message Center. See System Messages

Look for applicable Tech Notes and other troubleshooting resources under the "Troubleshoot and Alerts" heading on the product documentation page for your product.
