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.
This section includes the following topics:
• Online Diagnostics Overview, page 1-1
• Bootup Diagnostics, page 1-1
• Health Monitoring Diagnostics, page 1-2
• Expansion Module Diagnostics, page 1-3
Online Diagnostics Overview
Cisco Nexus 5000 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. Table 1-1
describes the diagnostics that are run only during switch bootup or reset.
