hi chan..

HA is possible with ZD1106, ZD1205 and ZD3000 controllers...

HA can be done in two ways:

Limited ZD discovery mode

- 2 controllers.  controller 1 is primary and controller 2 is secondary.
there is no sync between the two controllers... when primary controller goes down, AP's move to secondary controller and will join as it is joining a new controller, may get firmware upgraded or downgraded, configuration also get changed based on how old or new configuration was on the secondary controller

100 = SmartZone, not Zone Director

second mode is


2 controller, both controller are in active/standby mode however one controller is in action. all AP's are connected to active controller..
Both controller are in real time Sync in terms of firmware and configuration. Transition time is quick and WLAN network is restored in matter of minutes when active controller fails..

for any HA mode to be successful...

controller model should be same..
should have same no of licenses
should have same firmware version on both controller..
