Running Diagnostics on the Cisco12008 6-5
Loading and Running Diagnostics
Step2 Enter the password assigned to the system.
The prompt changes to the privileged EXEC prompt:
Router#
Step3 Determine the slot number of the card on which you want to run diagnostics.
Note Although you can run diagnostics concurrently on up to three line cards, the
recommended number is only one at a time. The cards will be taken offline and cannot pass
traffic.
Step4 Enter the diag command:
Router# diag slot
The diagnostic tests are downloaded and run. Test status and administrative messages are
returned to the system console. At the end of testing, a pass or fail message is displayed on
the console. The number of messages displayed depends on whether you included the
verbose option in the command.
Note Field diagnostics run limited tests of the switch fabric when testing a line card. This
provides a good method of troubleshooting switch fabric problems.
