Chapter 55 Configuring Generic Online Diagnostics

Configuring On-Demand Online Diagnostics

You can run the on-demand online diagnostic tests from the CLI. You can set the execution action to
either stop or continue the test when a failure is detected or to stop the test after a specific number of
failures occur by using the failure count setting. You can configure a test to run multiple times using the
iteration setting.
You should run packet-switching tests before memory tests.
Do not use the diagnostic start all command until all of the following steps are completed.
Note
Because some on-demand online diagnostic tests can affect the outcome of other tests, you should
perform the tests in the following order:
1.
2.
3.
4.
5.
To run on-demand online diagnostic tests, perform this task:
Run the non disruptive tests.
Step 1
To display the available tests and their attributes, and determine which commands are in the non
disruptive category, enter the show diagnostic content command.
Run all tests in the relevant functional area.
Step 2
Packet-switching tests fall into specific functional areas. When a problem is suspected in a particular
functional area, run all tests in that functional area. If you are unsure about which functional area you
need to test, or if you want to run all available tests, enter the complete keyword.
Run the TestTrafficStress test.
Step 3
This is a disruptive packet-switching test. This test switches packets between pairs of ports at line rate
for the purpose of stress testing. During this test all of the ports are shut down, and you may see link
flaps. The link flaps will recover after the test is complete. The test takes several minutes to complete.
Disable all health-monitoring tests f before running this test by using the no diagnostic monitor module
1 test all command.
Step 4 Run the TestEobcStressPing test.
This is a disruptive test and tests the Ethernet over backplane channel (EOBC) connection for the
module. The test takes several minutes to complete. You cannot run any of the packet-switching tests
described in previous steps after running this test. However, you can run tests described in subsequent
steps after running this test.
Disable all health-monitoring tests before running this test by using the no diagnostic monitor module
1 test all command. The EOBC connection is disrupted during this test and will cause the
health-monitoring tests to fail and take recovery action.
OL-4266-08
Run the non-disruptive tests.
Run all tests in the relevant functional area.
