Field Diagnostic ****PASSED**** for slot 7
Field Diag eeprom values: run 62 fail mode 0 (PASS) slot 7
last test failed was 0, error code 0
Shutting down diags in slot 7
Board will reload
These results are then stored in an Electrically Erasable Programmable Read-Only Memory (EEPROM) on the line
card. You can view the results of the last diagnostic performed on the line card with the diag <slot> previous
command. Here is a sample output:
Router#diag 3 previous
Field Diag eeprom values: run 0 fail mode 0 (PASS) slot 3
last test failed was 0, error code 0
If no previous field diagnostics have been performed on the card, the output looks like this:
Router#diag 3 previous
Field Diags have not been run on this board previously -
EE prom results uninitialized.
Field Diag eeprom values: run 16777215 fail mode 0 (PASS) slot 9
last test failed was 65535, error code 65535
There have been some bugs in the past that have caused the diagnostic tests to fail even though the card is not faulty,
so, as a precaution, if the line card fails and it has already been replaced previously, it would be useful to check this
output with the Technical Assistance Center (TAC).
Cisco IOS Software Releases Earlier than 12.0(22)S
Line card Field Diagnostic software is bundled with the main Cisco IOS Software to enable you to test whether or not
the suspect line card is faulty. To use this feature, you must be in privileged enable mode, and issue the diag <slot>
<verbose> command.
While the diagnostic test is in progress, the line card does not function normally and is not able to pass any traffic for
the duration of the test (5-15 minutes, based on the complexity of the line card). Without the verbose keyword, the
command gives a truncated output that shows a Pass or Fail for the card. The output of the diagnostic test without the
verbose command looks like this:
Router#diag 3
Running DIAG config check
Running Diags will halt ALL activity on the requested slot
