System Management Software Configuration Guide for Cisco IE 2000U and Connected Grid Switches

Chapter 18 Configuring Online Diagnostics

Prerequisites

Online diagnostics are categorized as on-demand, scheduled, or health-monitoring diagnostics.

• On-demand diagnostics run from the CLI.

• Scheduled diagnostics run at user-designated intervals or at specified times when the switch is

connected to a live network.

• Health-monitoring runs in the background.

Prerequisites

Before you enable any online diagnostics tests, enable console logging to see all warning messages. See

Chapter 13, “Configuring System Message Logging.”

Guidelines and Limitations

• 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 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 affect the test results. The switch must be rebooted to bring the

switch to normal operation. When you issue 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 other modules, after the test is initiated and complete, you must reset

the module.

• After starting the tests, you cannot stop the testing process.

Default Settings

By default, health monitoring is disabled. When enabled, the switch generates a syslog message when a

test fails.
