Understanding How Online Diagnostics Work

With online diagnostics, you can test and verify the hardware functionality of the supervisor engine,
modules, and switch while the switch is connected to a live network.
The online diagnostics contain packet switching tests that check different hardware components and
verify the data path and control signals. Disruptive online diagnostic tests, such as the built-in self-test
(BIST) and the disruptive loopback test, and nondisruptive online diagnostic tests, such as packet
switching, run during bootup, line card online insertion and removal (OIR), and system reset. The
nondisruptive online diagnostic tests run as part of background health monitoring or at the user's request
(on-demand).
The online diagnostics detect problems in the following areas:
