Bootup diagnostics also include a set of tests that are common with health monitoring diagnostics.
Bootup diagnostics log any failures to the onboard failure logging (OBFL) system. Failures also trigger an
LED display to indicate diagnostic test states (on, off, pass, or fail).
You can configure Cisco Nexus device to either bypass the bootup diagnostics or run the complete set of
bootup diagnostics.
Health Monitoring Diagnostics
Health monitoring diagnostics provide information about the health of the switch. They detect runtime hardware
errors, memory errors, software faults, and resource exhaustion.
Health monitoring diagnostics are nondisruptive and run in the background to ensure the health of a switch
that is processing live network traffic.
The following table describes the health monitoring diagnostics for the switch.
