How the system processes client maps

Whenever an FCC requests its assigned FSCs from the FSC, the system performs the following actions in the following order: A subnet/mask IP match is attempted. If a match is found, its assigned FSCs are returned. If there is no subnet/mask IP match and there are no domain name client maps defined: If the default IP client map was configured, its assigned FSCs are returned. If the default client map is not configured, a null is returned. If there is no IP subnet/mask match, but there is at least one dnszone or dnshostname attribute defined, a reverse DNS lookup of the FCC’s domain name address is performed. If the reverse DNS lookup fails and the dns_not_defined attribute is defined, its assigned FSCs are returned. If the reverse DNS lookup fails, but the dns_not_defined attribute is not defined, an error message is logged and a null value is returned. If the reverse DNS lookup succeeds, the domain name client maps are searched for a match. If one is found, its assigned FSCs are returned. If no domain name client map match is found and the default attribute is defined, its assigned FSCs are returned. If no domain name client map is matched and no default attribute is defined, the query fails and a null is returned.
