This is an example of a backup solution with three LANCOM WLC-4025s for
50 managed Access Points: Two of the WLAN Controllers each manage 25
Access Points and the third is available as a backup:
햲
Set the same time on all LANCOM WLAN Controllers
쐃
,
쐇
and
쐋
.
햳
Transfer the CA and RA certificates from the first primary WLAN Controller
쐃
to the second primary
쐇
and to the secondary "backup controller"

.
Primary and secondary controllers
The establishment of a WLAN Controller/Access Point connection is always initiated by the
Access Point. A LANCOM Access Point in managed mode will search the LAN for a WLAN
Controller that will provide the configuration. During this search the Access Point may find var-
ious suitable WLAN Controllers:
The WLAN Controller can authenticate the
certificate
in the Access Point and it has a
configuration
stored for the Access Point's MAC address. A WLAN Controller of this type
is described as a "primary" WLAN Controller.
A WLAN Controller can authenticate the
certificate
of an Access Point, but it has
neither
a
configuration
stored for the MAC address of the Access Point,
nor
does it have a
default configuration
. A WLAN Controller of this type is described as a "secondary"
WLAN Controller.
