Enabling Smart Redundancy
ZoneDirector’s Smart Redundancy feature allows two ZoneDirectors to be config-
ured as a redundant pair, with one unit actively managing your ZoneFlex network
while the other serves as a backup in standby mode, ready to take over if the first
unit fails or loses power.
Each ZoneDirector will either be in active or standby state. If the active ZoneDirector
fails, the standby device becomes active. When the original active device recovers,
it automatically assumes the standby state as it discovers an already active
ZoneDirector on the network.
The ZoneDirector in active state manages all APs and client connections. The
ZoneDirector in standby state is responsible for monitoring the health of the active
unit and periodically synchronizing its settings to match those of the active device.
The ZoneDirector in standby state will not respond to Discovery requests from APs
and changing from active to standby state will release all associated APs.
When failover occurs, all associated APs will continue to provide wireless service to
clients during the transition, and will associate to the newly active ZoneDirector
within approximately one minute.
