Performing Diagnostics
You can use diagnostics to test and verify the functionality of the hardware components of your system
(chassis, supervisor engines, modules, and ASICs) while your Catalyst 4500 series switch is connected
to a live network. Diagnostics consists of packet-switching tests that test hardware components and
verify the data path and control signals.
Online diagnostics are categorized as bootup, on-demand, schedule, or health-monitoring diagnostics.
Bootup diagnostics run during bootup; on-demand diagnostics run from the CLI; scheduled diagnostics
run at user-designated intervals or specified times when the switch is connected to a live network; and
health-monitoring runs in the background.
This chapter consists of these sections:
• Configuring Online Diagnostics, page 71-1
