Configuring Zonedirector For Smart Redundancy - Ruckus Wireless ZoneDirector 1100 User Manual

Configuring System Settings
Enabling Smart Redundancy
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.
NOTE: This feature is only available using two ZoneDirectors of the same model and number
of licensed APs. You can not enable Smart Redundancy using a ZoneDirector 3000 as the
primary and a ZoneDirector 1100 as the backup unit, for example.

Configuring ZoneDirector for Smart Redundancy

For management convenience, both ZoneDirectors in a Smart Redundancy deployment can
be managed via a single shared IP address. In this situation, three IP addresses would need to
be configured:
• Primary ZoneDirector's real address
• Backup ZoneDirector's real address
• Management address
All configuration changes are made to the active ZoneDirector and synchronized to the standby
unit. The user can access the Web interface from any of the three IP addresses, however not
all configuration options are available from the standby device.
NOTE: If you will be deploying the two ZoneDirectors on different Layer 3 networks, you must
ensure that Port 443 and Port 33003 are open in any routers and firewalls located between the
two ZoneDirectors.
To enable Smart Redundancy:
1. Log in to the Web interface of the ZoneDirector you will initially designate as the primary
unit.
2. Go to Configure > System, and set a static IP address under Device IP Settings, if not
already configured.
3. Click Apply. You will need to log in again using the new IP address (if changed).
4. On the same Configure > System page, locate the Smart Redundancy section.
