Hi Uriel,
Unfortunately there is no API interface for the Zone Director (and Unleashed) controllers.
Besides the integrated GUI and CLI interfaces for configuration and monitoring, both the ZD and ZD controlled AP's have SNMP interfaces which can be used for monitoring (get), configuration (set) and alarms (traps). MIBs for each version are published on the Ruckus support site.
I hope this answers your question.
Thank you for choosing Ruckus Networks products - a Commscope company.
