Information About Online Diagnostics

Online diagnostics provide verification of hardware components during switch bootup or reset, and they
monitor the health of the hardware during normal switch operation.
Cisco Nexus Series switches support bootup diagnostics and runtime diagnostics. Bootup diagnostics include
disruptive tests and nondisruptive tests that run during system bootup and system reset.
Runtime diagnostics (also known as health monitoring diagnostics) include nondisruptive tests that run in the
background during normal operation of the switch.

Bootup Diagnostics

Bootup diagnostics detect faulty hardware before bringing the switch online. Bootup diagnostics also check
the data path and control path connectivity between the supervisor and the ASICs. The following table describes
the diagnostics that are run only during switch bootup or reset.
