Overview
Parameter dictionaries are XML files that list valid objects and parameters that Cisco BAC uses to
configure a CWMP device. The dictionaries validate the objects and parameters used in the configuration
and firmware rule templates.
Parameter dictionaries provide metadata about the supported objects and parameters, such as name, type,
writeability and readability. Each dictionary is stored in a file and added to the RDU through the
management API or the administrator user interface.
Configuration and firmware rule templates include a ParameterDictionary tag, an indicator of which
dictionary defines the parameters in a given template. Cisco BAC validates configuration and firmware
rule templates by using the dictionary to which the templates refer. All parameter names and values in
the configuration and firmware rule template must be compatible with the parameters referenced in the
parameter dictionary.
