Configuring the Built-in DHCP Server
Forcing Failover to the Backup ZoneDirector

Ruckus Wireless, Inc.
NOTE: If you disable Smart Redundancy after it has been enabled, both
ZoneDirectors will revert to active state, which could result in unpredictable network
topologies. Therefore, Ruckus Wireless recommends first factory resetting the
standby ZoneDirector before disabling Smart Redundancy.
NOTE: If the active and standby ZoneDirector are on different IP subnets, APs need
to know the IP addresses of both ZoneDirectors to quickly find the active
ZoneDirector after a Smart Redundancy failover. You can do this by configuring the
IP addresses of both devices on the Configure > Access Points > Limited ZD
Discovery page. Specify one ZoneDirector as Primary, the other as Secondary.
Alternatively you can specify the IP addresses of both ZoneDirectors through DHCP
Option 43 (see
Option 2: Customize Your DHCP Server ).
Forcing Failover to the Backup ZoneDirector
After Smart Redundancy has been enabled, you can view the status of both the
primary and backup units from the Dashboard by dragging the Smart Redundancy
widget onto the workspace.

The
Failover
button can be used to force a role reversal making the standby
ZoneDirector the active unit. This widget also displays the state (active, standby or
disconnected) of both devices, as well as their IP addresses and the Management
IP address, if configured.
Configuring the Built-in DHCP Server
ZoneDirector comes with a built-in DHCP server that you can enable to assign IP
addresses to devices that are connected to it. ZoneDirector’s DHCP server will only
assign addresses to devices that are on its own subnet and part of the same VLAN
(if VLANs are assigned).
