After you configure diagnostic tests to run on the switch, use the diagnostic start privileged EXEC command to begin diagnostic testing.

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

Use this privileged EXEC command to manually start online diagnostic testing.

You can schedule online diagnostics to run at a designated time of day or on a daily, weekly, or monthly basis for a switch. Use the no form of this command to remove the scheduling.

Use the no form of this command to disable testing.

By default, health monitoring is disabled, but the Switch generates a syslog message when a test fails.

Follow these steps to configure and enable the health-monitoring diagnostic tests:

After you configure diagnostic tests to run on the switch, use the diagnostic start privileged EXEC command to begin diagnostic testing.

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

Use this privileged EXEC command to manually start online diagnostic testing.

This example shows how to configure a health-monitoring test:

Switch(config)# diagnostic monitor threshold switch 1 test 1 failure count 50
Switch(config)# diagnostic monitor interval switch 1 test TestPortAsicStackPortLoopback

This example shows how to schedule diagnostic testing for a specific day and time on a specific switch:

Switch(config)# diagnostic schedule test DiagThermalTest on June 3 2013  22:25

This example shows how to schedule diagnostic testing to occur weekly at a certain time on a specific switch:

Switch(config)# diagnostic schedule switch 1 test 1,2,4-6 weekly saturday 10:30

This example shows how to display the online diagnostic detailed information on a specific switch:

Switch# show diagnostic switch 1 detail

Switch 1: SerialNo :

  P/V/* - Per port test / Per device test / NA
  D/N/* - Disruptive test / Non-disruptive test / NA

    X/* - Not a health monitoring test / NA
    F/* - Fixed monitoring interval test / NA
    E/* - Always enabled monitoring test / NA
    A/I - Monitoring is active / Monitoring is inactive
    R/* - Switch will reload after test list completion / NA
    P/* - will partition stack / NA
