LANCOM WLAN controllers manage a large number of access points, which in turn may have a large number of WLAN clients associated with them. WLAN controllers thus play a crucial role in the functioning of the entire WLAN infrastructure—for which reason the organization of a backup solution in case of temporary WLAN controller failure is in many cases indispensable.
In case of a backup event, a managed access point should connect to an alternative WLAN controller. Because this connection will only function if the certificate in the access point has been authorized by the backup controller, it is essential that all WLAN controllers sharing a backup solution have identical root certificates.
