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
on page 27).
Managing Smart Redundancy AP License Pools
If two Smart Redundancy ZoneDirectors have different license levels (number of licensed
APs), the total number of licenses is displayed in the Smart Redundancy dashboard
widget, in the “License Pool” entry. When one device is disconnected, the remaining
active ZD will continue to use the previous total license pool and start a 60-day timer.
When the timer expires, the ZD will use its own license number (the license pool is
reduced to the number of APs licensed for the currently active device only) until its Smart
Redundancy peer comes back online.
If a third ZoneDirector connects, the license pool will reflect the new total license pool if
the sum of the two licenses is higher than the original pair. If the sum is less than the
previous license pool (within the 60-day timer), the user will be prompted to choose
whether the license pool will be derived from the original disconnected device,
or from the currently current standby device. License pools cannot exceed the
maximum individual ZD license limit. ZoneDirectors with temporary licenses cannot be
configured as part of a Smart Redundancy pair.
