Online Diagnostic Tests
This appendix describes the online diagnostic tests and provides recommendations for how to use them.
Note • For information about configuring online diagnostic tests refer to Chapter 55, “Configuring Generic
Online Diagnostics.”
• We recommend that before you enable any online diagnostics tests that you enable the logging
console/monitor to see all warning messages.
• We recommend that when you are running disruptive tests that you only run the tests when
connected through console. When disruptive tests are complete a warning message on the console
recommends that that you reload the system to return to normal operation: Strictly follow this
warning.
• While tests are running, all ports are shut down as a stress test is being performed with looping ports
internally and external traffic might skew the test results. The entire switch must be rebooted to
bring the switch to normal operation. When you issure the command to reload the switch, the system
will ask you if the configuration should be saved.
• Do not save the configuration.
• If you are running the tests on a supervisor engine, after the test is initiated and complete, you must
reload or power down and then power up the entire system.
• If you are running the tests on a module that is not the supervisor engine, after the test is initiated
and complete, you must reset the module.
