Line Card Diagnostics Using Cisco IOS Software Releases Prior to 12.0(22)S

Output from this procedure will vary slightly depending on which line card you are using, but the basic
information will be the same.
Line card field diagnostic software is bundled with the main Cisco IOS software to enable you to test
whether a 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 running, the line card does not function normally and cannot pass any traffic
for the duration of the testing. Without the verbose keyword, the command provides a truncated output
message. When communicating with the Cisco TAC, the verbose mode is helpful in identifying specific
problems. The output of the diagnostic test without the verbose command appears like the following
Router#diag 3
Running DIAG config check
Running Diags will halt ALL activity on the requested slot
Launching a Field Diagnostic for slot 3

slot 3 done, will not reload automatically
The line card reloads automatically only after passing the test. In the example above, the line card failed
the test and did not reload automatically. You can manually reload the line card by using the hw-module
slot slot reload command.
Field diagnostic results are stored in an EEPROM on the line card. It is possible to view the results of
the last diagnostic test performed on the line card by executing the diag slot previous command.
There are some caveats that exist that cause diagnostic tests to fail, even though the line card is not faulty.
As a precaution, if the line card fails and had been replaced previously, you should review this output
with the Cisco TAC.
