Understanding How Online Diagnostics Work
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.
Scheduling Online Diagnostics
You can schedule online diagnostics to run at a designated time of day or on a daily, weekly, or monthly
basis for a specific switch. Use the no form of this command to remove the scheduling.
