Information About Configuring Online Diagnostics

Online Diagnostics
With online diagnostics, you can test and verify the hardware functionality of the Switch while the Switch is
connected to a live network.
The online diagnostics contain packet switching tests that check different hardware components and verify
the data path and the control signals.
The online diagnostics detect problems in these areas:
• Hardware components
• Interfaces (Ethernet ports and so forth)
• Solder joints
Online diagnostics are categorized as on-demand, scheduled, or health-monitoring diagnostics. On-demand
diagnostics run from the CLI; scheduled diagnostics run at user-designated intervals or at specified times
when the Switch is connected to a live network; and health-monitoring runs in the background with user-defined
intervals. By default, the health-monitoring test runs for every 30 seconds.
After you configure online diagnostics, you can manually start diagnostic tests or display the test results. You
can also see which tests are configured for the Switch or switch stack and the diagnostic tests that have already
run.
