Configuration Errors
If you set the fields in the configuration file to invalid or unsupported values, the
module ignores the invalid configuration, generates a non-critical error, and keeps
operating with the previous configuration.
The
Configuration Error Codes table on page 117 lists the possible
module-specific configuration error codes defined for the module. Correct the
error by providing proper configuration data to the module.
Table 21 describes configuration errors in more general terms.
