Diagnostic Test Overview
Note
or 12.0ST, the default download method changes from the mbus to the switch fabric. It
takes about 1-minute to obtain test results from the switch fabric compared to 15-minutes
to obtain test results from the mbus.
While diagnostics are running, the line card being tested is controlled by the diagnostic
software. Diagnostics take the line card under test offline. The diagnostics affect just the
line card being tested; the rest of the line cards remain online and continue to pass traffic
normally.
Except for the tests on the clock and scheduler cards (CSCs) and the switch fabric cards
(SFCs), which may temporarily drop throughput on those cards, the diagnostics do not
affect system performance.
Diagnostic testing stops at the completion of all of the tests, when terminated by the user,
or by default when an error is encountered. If multiple cards are specified for the test cycle,
the diagnostics stop testing a card when it fails a test, but continue testing the remaining
cards.
Note
an error is encountered. This is not recommended for use on operational, business-critical
routers.
When testing is finished, a pass or fail message displays on the console, as well as on the
alphanumeric LED display on the card being tested.
