Understanding 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
v
erify 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.
O
n-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.
Configuring Online Diagnostics
You must configure the failure threshold and the interval between tests before enabling diagnostic
monitoring.
