Line Card Diagnostics Using Cisco IOS Software Releases Prior to 12.0(22)S
Note 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
example:
Router#diag 3
Running DIAG config check
Running Diags will halt ALL activity on the requested slot
[confirm]
Router#
