Information About Configuring Online Diagnostics
With online diagnostics, you can test and verify the hardware functionality of the device while the device 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:
Interfaces (Ethernet ports and so forth)
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 device is connected to a live network; and health-monitoring runs in the background with user-defined intervals. The health-monitoring test runs for every 90, 100, or 150 seconds based on the test.
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 device or switch stack and the diagnostic tests that have already run.
