Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Chapter: Configuring Online Diagnostics

Configuring Online Diagnostics

This chapter describes how to configure the online diagnostics on the Cisco ME 3800X and ME 3600X switch.

Note For complete syntax and usage information for the commands used in this chapter, see the command reference for this release.

Understanding Online Diagnostics

With online diagnostics, you can test and verify the hardware functionality of the switch while the switch is connected to a live network. The online diagnostics contain packet switching tests that monitor different hardware components and verify the data path and the control signals.

The online diagnostics detect problems in these areas:

  • Hardware components
  • Interfaces (Ethernet ports and so forth)
  • Solder joints

Table 66-1 lists the diagnostic test IDs and names. For information about test attributes, see the output from the show diagnostic content privileged EXEC command.

 

Table 66-1 Diagnostic Tests
Test ID Number
Test Name

1

TestPortAsicMem [B*D*R**]

2

TestPortAsicCam [B*D*R**]

3

TestPortAsicLoopback[B*D*R**]

4

TestPortLoopback [B*D*R**]

5

TestFpga [B*D*R**]

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.

Configuring Online Diagnostics

You must configure the failure threshold and the interval between tests before enabling diagnostic monitoring. You can schedule online diagnostics to run at a designated time of day or on a daily, weekly, or monthly basis. Use the no form of this command to remove the scheduling. For detailed information about this command, see the command reference for this release.

Beginning in privileged EXEC mode, follow these steps to schedule online diagnostics:

 

Command
Purpose

Step 1

configure terminal

Enter global configuration mode.

Step 2

diagnostic schedule test { name | test-id | test-id-range | all | basic } { daily hh : mm | on mm dd yyyy hh : mm | weekly day-of-week hh : mm }

Schedule on-demand diagnostic tests for a specific day and time.

When specifying the tests to be scheduled, use these options:

  • name —Name of the test that appears in the show diagnostic content command output. See Table 66-1 .
  • test-id —ID number of the test that appears in the show diagnostic content command output. See Table 66-1 .
  • test-id-range —A range of test ID numbers separated by a hyphen or commas.
  • all —All of the diagnostic tests.
  • basic —Basic on-demand diagnostic tests.

You can schedule the tests for these time periods:

  • Daily—Use the daily hh : mm parameter.
  • Specific day and time—Use the on mm dd yyyy hh : mm parameter.
  • Weekly—Use the weekly day-of-week hh : mm parameter.

Step 3

show diagnostic { content | schedule }

Verify the configured online diagnostic tests and schedule.

  • Enter show diagnostic content to display the configured online diagnostics.
  • Enter show diagnostic schedule to display the online diagnostics test schedule.

Step 4

copy running-config startup-config

(Optional) Save your entries in the configuration file.

Use the no diagnostic schedule test { name | test-id | test-id-range | all | basic } { daily hh : mm | on mm dd yyyy hh : mm | weekly day-of-week hh : mm } global configuration command to remove the scheduled tests.

This example shows how to schedule diagnostic testing for a specific day and time and verify the schedule:

Switch(config)# diagnostic schedule test 1 on Dec 4 2008 10:22
Switch(config)# end
Switch# show diagnostic schedule
Current Time = 10:21:24 UTC Thu Dec 4 2008
 
Diagnostic:
 
Schedule #1:
To be run on December 4 2008 10:22
Test ID(s) to be executed: 1.
 

At the scheduled time, the switch runs the test:

Switch# #
Dec 4 10:21:59.492: %DIAG-6-SCHED_RUNNING: : Performing Scheduled Online Diagnostic...
Dec 4 10:21:59.492: %DIAG-6-TEST_RUNNING: : Running TestPortAsicStackPortLoopback{ID=1}..
Dec 4 10:22:00.498: %DIAG-6-TEST_OK: : TestPortAsicStackPortLoopback{ID=1} has completed successfully
Dec 4 10:22:00.498: %DIAG-6-SCHED_COMPLETE: : Scheduled Online Diagnostic is completed
 

For more examples, see the “Examples” section for the diagnostic schedule test command in the command reference for this release.

Running Online Diagnostic Tests

After you configure online diagnostics, you can manually start diagnostic tests or display the test results. You can also see the tests configured for the switch and the tests that have already run.

Starting Online Diagnostic Tests

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

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

 

Command
Purpose

diagnostic start test { name | test-id | test-id-range | all | basic }

Start the diagnostic tests.

Specify the tests by using one of these parameters:

  • name —Enter the name of the test. Use the show diagnostic content privileged EXEC command to display the test ID list. See Table 66-1 .
  • test-id —Enter the ID number of the test. Use the show diagnostic content privileged EXEC command to display the test ID list. See Table 66-1 .
  • test-id-range —Enter the range of test IDs by using integers separated by a comma and a hyphen. For more information, see the diagnostic start command in the command reference for this release.
  • all —Use this keyword when you want to run all of the tests.
  • basic —Use this keyword when you want to run the basic test suite.

This example shows how to start a diagnostic test by using the test name:

Switch# diagnostic start test TestPortAsicRingLoopback
 

This example shows how to start all of the basic diagnostic tests:

Switch# diagnostic start test all

Displaying Online Diagnostic Tests and Results

You can display the configured online diagnostic tests and review the test results by using the privileged EXEC show commands in Table 66-2 .

 

Table 66-2 Commands for Diagnostic Test Configuration and Results

Command
Purpose

show diagnostic content

Displays the online diagnostics configured for a switch.

show diagnostic status

Displays the running diagnostic tests.

show diagnostic result [ detail | test { name | test-id | test-id-range | all [ detail ]}]

Displays the specified online diagnostics test results.

show diagnostic switch [ detail ]

Displays the online diagnostics test results.

show diagnostic schedule

Displays the online diagnostics test schedule.

show diagnostic post

Displays the POST results. (The output is the same as the show post command output.)

This is an example of the output from the show diagnostic result command:

Switch# show diagnostic result
 
: SerialNo : FOC1225U4CY
 
Overall diagnostic result: PASS
 
Test results: (. = Pass, F = Fail, U = Untested)
 
1) TestPortAsicStackPortLoopback --->.
2) TestPortAsicLoopback ------------> U
3) TestPortAsicCam -----------------> U
4) TestPortAsicRingLoopback --------> U
5) TestMicRingLoopback -------------> U
6) TestPortAsicMem -----------------> U
 

This is an example of the output from the show diagnostic post command:

Switch# show diagnostic post
Stored system POST messages:
 
Switch 1

POST: CPU MIC register Tests : Begin
POST: CPU MIC register Tests : End, Status Passed
 
POST: PortASIC Memory Tests : Begin
POST: PortASIC Memory Tests : End, Status Passed
 
POST: CPU MIC interface Loopback Tests : Begin
POST: CPU MIC interface Loopback Tests : End, Status Passed
 
POST: PortASIC RingLoopback Tests : Begin
POST: PortASIC RingLoopback Tests : End, Status Passed
 
POST: Thermal, Fan Tests : Begin
POST: Thermal, Fan Tests : End, Status Passed
 
POST: PortASIC CAM Subsystem Tests : Begin
POST: PortASIC CAM Subsystem Tests : End, Status Passed
