There are two types of online diagnostic tests:

Online diagnostics is one of the requirements for the high-availability feature. High availability is a set
of quality standards that seek to limit the impact of equipment failures on the network. A key part of high
availability is detecting hardware failures and taking corrective action while the switch runs in a live
network. Online diagnostics in high availability detect hardware failures and provide feedback to
high-availability software components to make switchover decisions.

Specifying the Bootup Online Diagnostic Level

You can specify the bootup online diagnostics level as minimal or complete, or you can bypass the
bootup diagnostics entirely. Enter the complete keyword to run all diagnostic tests; enter the minimal
keyword to run only PFC tests for the supervisor engine and loopback tests for all ports in the switch;
enter the bypass keyword to bypass all diagnostic tests. The default bootup diagnostics level is minimal.
Note Although the default is minimal, we recommend that you set the bootup online diagnostics level to
complete. We do not recommend bypassing the bootup online diagnostics.

Bootup—Bootup diagnostics run during bootup, module OIR, or switchover to a backup supervisor
engine.
On-demand—On-demand diagnostics run from the CLI.
Schedule—Schedule diagnostics run at user-designated intervals or specified times when the switch
is connected to a live network.
Health monitoring—Health-monitoring diagnostics run in the background.
Disruptive online diagnostic tests—These tests include the built-in self-test (BIST) and the
disruptive loopback test.
Nondisruptive online diagnostic tests—These tests include packet switching, and run during bootup,
line card online insertion and removal (OIR), and system reset diagnostic tests. The nondisruptive
online diagnostic tests run as part of the background health monitoring or at your request
(on-demand).
