Chapter 4: Configuring the WLAN Controller
70
EN
햴
Configure the first WLAN Controller
쐃
according to your requirements
with all profiles and the associated AT table. The Access Points then estab-
lish connections to the first WLAN Controller. Each Access Point receives
a valid certificate and a configuration for the WLAN module from the
WLAN Controller.
햵
Transfer the configuration from the first WLAN Controller
쐃
, for example
using LANconfig, to the backup controller
쐇
. The profiles and the AP
tables with the Access Point MAC addresses are transferred to the backup
controller at the same time. All Access Points remain logged on to the first
WLAN Controller.
햶
Should WLAN Controller
쐃
fail, the Access Points will automatically
search for another WLAN Controller and they will find the backup control-
ler
쐇
. Because this has the same root certificate, it is able to check the
validity of the Access Points' certificates. Because the Access Points are
also entered into the backup controller's AP table along with their MAC
addresses, the backup controller can fully take over the management of
the Access Points. Changes to the WLAN profiles in the backup controller
will directly affect the managed Access Points.
In this scenario, the Access Points remain under the management of
the backup controller until this itself becomes unavailable or is man-
ually disconnected (’Disconnect Access Point’
→
Page 78).
If the Access Points are set up for self-sufficient operation (’Self-suf-
ficient operation’
→
Page 53) they will remain operational while
searching for a backup controller, and the WLAN clients will remain
associated.
Backup with primary and secondary WLAN Controllers
This second type of backup you can provide a larger number of "primary"
WLAN Controllers with one common "secondary" backup controller. In case a
WLAN Controller should fail, the Access Points remain operational but they
work with the current configuration of the WLAN modules. As a secondary
controller, the backup controller cannot assign any configuration changes to
the Access Points.
