While many Unleashed commands come from ZoneDirector, not all commands/features from ZD are supported in Unleashed.

• Tunneled WLANs are not supported.
• IPv6 is not supported.
• No interface to communicate with SmartCell Insight, SPoT, or the ZoneDirector Remote Control mobile app.
• No North Bound Interface to pass client authentication responsibility to an external entity.
