At system startup, a LANCOM WLAN controller generates the basic certificates for the assignment of certificates to the access points, including the root certificates for the CA (Certification Authority) and the RA (Registration Authority). Based on these two certificates, the WLAN controller issues device certificates for the access points.
If multiple WLAN controllers are employed in parallel in the same WLAN infrastructure (for load balancing) or if a device is being replaced or reconfigured, the same root certificates should always be used to avoid problems with the operation of the managed access points.
