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

GOLD diagnostics are divided into the following types:

·     Monitoring diagnostics—Run diagnostic tests periodically when the system is in operation and record test results. Monitoring diagnostics execute only non-disruptive tests.

·     On-demand diagnostics—Enable you to manually start or stop diagnostic tests during system operation.

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.

GOLD tasks at a glance

To configure GOLD, perform the following tasks:

1.     Configuring diagnostics

Choose the following tasks as needed:

¡     Configuring monitoring diagnostics

¡     Configuring on-demand diagnostics

¡     Configuring script-bound 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.

diagnostic monitor enable 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.

diagnostic monitor interval 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.

Configuring on-demand diagnostics

About this task

You can stop an on-demand diagnostic test by using any of the following commands:

·     Use the diagnostic ondemand stop command to immediately stop the test.

·     Use the diagnostic ondemand repeating command to configure the number of executions for the test.

·     Use the diagnostic ondemand failure command to configure the maximum number of failed tests before the system stops the test.

Restrictions and guidelines

The diagnostic ondemand commands are effective only during the current system operation. These commands are restored to the default after you restart the device.

Procedure

·     To configure on-demand diagnostics, perform the following steps in user view:

1.     Configure the number of executions.

diagnostic ondemand repeating repeating-number

The default value for the repeating-number argument is 1.

This command applies only to diagnostic tests to be enabled.

2.     Configure the number of failed tests.

diagnostic ondemand failure failure-number

By default, the maximum number of failed tests is not specified.

Configure a number no larger than the configured repeating-number argument.

This command applies only to diagnostic tests to be enabled.

3.     Enable on-demand diagnostics.

diagnostic ondemand start slot slot-number-list test { test-name | non-disruptive } [ para parameters ]

The system runs the tests according to the default configuration if you do not perform the first two configurations.

4.     (Optional.) Stop on-demand diagnostics.

diagnostic ondemand stop slot slot-number-list test { test-name | non-disruptive }

You can manually stop all on-demand diagnostic tests.

Configuring script-bound diagnostics

About this task

The device is configured with tests that are bound with scripts before the device is shipped. The system supports TCL and shell scripts, such as scripts for verifying chip and port basic information after the device is powered on. After you use this command to start a test, the system automatically runs the scripts and displays the results at the CLI.

Procedure

To start script-bound diagnostics, execute the following command in user view:

diagnostic start test test-name [ parameters ]

Simulating diagnostic tests

About this task

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.

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:

diagnostic simulation 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.

GOLD configuration examples

Support for the diagnostic tests depends on the device model. Monitoring diagnostic test MonitorTest in the following configuration examples is for illustration only.
