show diag command output. The state of the module is reported as present but disabled.
If the most capable module slot and port do not match the interface ids slot/port configuration
command, the most capable module is disabled with the following warning:
The module in slot x will be disabled and configuration ignored.
The correct slot/port number are displayed so that you can change the configuration.
