Configuring GOLD

Generic Online Diagnostics (GOLD) performs the following operations:

·     Runs diagnostic tests on a device to inspect device ports, RAM, chip, connectivity, forwarding paths, and control paths for hardware faults.

·     Reports the problems to the system.

The device supports only monitoring diagnostics. Monitoring diagnostics run diagnostic tests periodically when the system is in operation and record test results. Monitoring diagnostics execute only non-disruptive tests.

Diagnostic tests are used for diagnostics. The parameters of a diagnostic test include test name, type, description, attribute (disruptive or non-disruptive), default status, and execution interval.

Support for the diagnostic tests and default values for a test's parameters depend on the device model. You can modify part of the parameters by using the commands provided by this document.

The diagnostic tests are released with the system software image of the device. All enabled diagnostic tests run in the background. You can use the display commands to view test results and logs to verify hardware faults.

Configuring monitoring diagnostics

The system automatically executes monitoring diagnostic tests that are enabled by default after the device starts. Use the diagnostic monitor enable command to enable monitoring diagnostic tests that are disabled by default.

Use the diagnostic monitor interval command to configure an execution interval for each test. The interval you set must be no smaller than the minimum interval for each test. You can view the minimum interval for a test by using the display diagnostic content command.

(In standalone mode.) To configure monitoring diagnostics:

 

Step

Command

Remarks

1.     Enter system view.

system-view

N/A

2.     Enable monitoring diagnostics.

diagnostic monitor enable slot slot-number-list [ test test-name ]

By default, the settings for this command vary by test. Use the display diagnostic content command to view the status of a monitoring diagnostic test.

3.     Set the execution interval.

diagnostic monitor interval slot slot-number-list [ test test-name ] time interval

By default, the settings for this command vary by test. Use the display diagnostic content command to view the execution interval for a test.

 

(In IRF mode.) To configure monitoring diagnostics:

 

Step

Command

Remarks

1.     Enter system view.

system-view

N/A

1.     Enable monitoring diagnostics.

diagnostic monitor enable chassis chassis-number slot slot-number-list [ test test-name ]

By default, the settings for this command vary by test. Use the display diagnostic content command to view the status of a monitoring diagnostic test.

2.     Set the execution interval.

diagnostic monitor interval chassis chassis-number slot slot-number-list [ test test-name ] time interval

By default, the settings for this command vary by test. Use the display diagnostic content command to view the execution interval for a test.

 

Simulating test results

Test simulation verifies GOLD frame functionality. When you use the diagnostic simulation commands to simulate a diagnostic test, only part of the test code is executed to generate a test result. Test simulation does not trigger hardware correcting actions such as device restart and active and standby switchover.

To simulate a test:

 

Task

Command

Remarks

Simulate a test.

·     In standalone mode:
diagnostic simulation slot
slot-number-list test test-name { failure | random-failure | success }

·     In IRF mode:
diagnostic simulation chassis
chassis-number slot slot-number-list test test-name { failure | random-failure | success }

By default, the system runs a test instead of simulating it.

 

Configuring the log buffer size

GOLD saves test results in the form of logs. You can use the display diagnostic event-log command to view the logs.

To configure the GOLD log buffer size:

 

Task

Command

Remarks

1.     Enter system view.

system-view

N/A

2.     Configure the maximum number of GOLD logs that can be saved.

diagnostic event-log size number

By default, GOLD saves 512 log entries at most.

When the number of logs exceeds the configured log buffer size, the system deletes the oldest entries.

 

Displaying and maintaining GOLD

(In standalone mode.) Execute display commands in any view and reset commands in user view.

 

Task

Command

Display test content.

display diagnostic content [ slot slot-number ] [ verbose ]

Display GOLD logs.

display diagnostic event-log [ error | info ]

Display test results.

display diagnostic result [ slot slot-number [ test test-name ] ] [ verbose ]

Display configurations for simulated tests.

display diagnostic simulation [ slot slot-number ]

Clear GOLD logs.

reset diagnostic event-log

Clear test results.

reset diagnostic result [ slot slot-number [ test test-name ] ]

 

(In IRF mode.) Execute display commands in any view and reset commands in user view.

 

Task

Command

Display test content.

display diagnostic content [ chassis chassis-number [ slot slot-number ] ] [ verbose ]

Display GOLD logs.

display diagnostic event-log [ error | info ]

Display test results.

display diagnostic result [ chassis chassis-number [ slot slot-number [ test test-name ] ] ] [ verbose ]

Display configurations for simulated tests.

display diagnostic simulation [ chassis chassis-number [ slot slot-number ] ]

Clear GOLD logs.

reset diagnostic event-log

Clear test results.

reset diagnostic result [ chassis chassis-number [ slot slot-number [ test test-name ] ] ]
