Configuring GOLD

About 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.

Types of GOLD diagnostics

The device supports only monitoring diagnostics.

Monitoring diagnostics run diagnostic tests periodically when the system is in operation and record test results. Only non-disruptive tests are executed.

 

GOLD diagnostic tests

Each kind of diagnostics runs its diagnostic tests. 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.

Restrictions and guidelines: GOLD configuration

GOLD is supported only on the default MDC. The non-default MDCs do not support GOLD.

GOLD tasks at a glance

To configure GOLD, perform the following tasks:

1.     Configuring diagnostics

¡     Configuring monitoring diagnostics

2.     (Optional.) Simulating diagnostic tests

3.     (Optional.) Configuring the log buffer size

Configuring monitoring diagnostics

About this task

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.

Procedure

1.     Enter system view.

system-view

2.     Enable monitoring diagnostics.

In standalone mode:

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

In IRF mode:

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

By default, the monitoring diagnostic tests vary in enabling status. To view the enabling status of a monitoring diagnostic test, execute the display diagnostic content command.

3.     Set an execution interval for monitoring diagnostic tests.

In standalone mode:

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

In IRF mode:

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

By default, the execution interval varies by monitoring diagnostic test. To display the execution interval of a monitoring diagnostic test, execute the display diagnostic content command.

The configured interval cannot be smaller than the minimum execution interval of the tests. Use the display diagnostic content verbose command to view the minimum execution interval of the tests.

Simulating diagnostic tests

About this task

You can simulate monitoring diagnostic tests to verify 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/standby switchover.

Restrictions and guidelines

Only monitoring diagnostics and on-demand diagnostics support test simulation.

Procedure

To simulate a test, execute the following command in user view:

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

About this task

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

Procedure

1.     Enter system view.

system-view

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.

Display and maintenance commands for GOLD

Execute display commands in any view and reset commands in user view.

 

Task	Command
Display test content.	In standalone mode: display diagnostic content [ slot slot-number ] [ verbose ] In IRF mode: display diagnostic content [ chassis chassis-number [ slot slot-number ] ] [ verbose ]
Display GOLD logs.	display diagnostic event-log [ error | info ]
Display test results.	In standalone mode: display diagnostic result [ slot slot-number [ test test-name ] ] [ verbose ] In IRF mode: display diagnostic result [ chassis chassis-number [ slot slot-number [ test test-name ] ] ] [ verbose ]
Display statistics for packet-related tests.	In standalone mode: display diagnostic result [ slot slot-number [ test test-name ] ] statistics In IRF mode: display diagnostic result [ chassis chassis-number [ slot slot-number [ test test-name ] ] ] statistics
Display configurations for simulated tests.	In standalone mode: display diagnostic simulation [ slot slot-number ] In IRF mode: display diagnostic simulation [ chassis chassis-number [ slot slot-number ] ]
Clear GOLD logs.	reset diagnostic event-log
Clear test results.	In standalone mode: reset diagnostic result [ slot slot-number [ test test-name ] ] In IRF mode: reset diagnostic result [ chassis chassis-number [ slot slot-number [ test test-name ] ] ]

GOLD configuration examples

Support for the diagnostic tests depends on the device model. The diagnostic test named MonitorTest used in the following examples is for illustration only.
