WLC

LCOS LX-based access points can be managed by a R&S®NC WLAN controller (WLC). Like LCOS-based access points, they use the CAPWAP protocol.

Important: The prerequisite for this is a R&S®NC WLAN controller with LCOS version 10.40 or higher.

Note: For background information on WLAN management with R&S®NC WLAN controllers, see the section "WLAN management" in the LCOS reference manual.

In their factory default settings, LCOS LX-based access points search the local network for a WLAN controller. They also query the DNS name "WLC-Address" to try to reach a WLAN controller.

Note: An access point will not try to contact the R&S®LANCOM Management Cloud if it is already being managed by a WLC.

Note: If the access point is managed by the R&S®LANCOM Management Cloud and a WLAN configuration is rolled out to the access point by the LMC in this context, the access point will no longer attempt to contact a WLC.

This make it possible to use zero-touch commissioning, which means that no further configuration of the access point is necessary. A manual configuration may still be necessary in certain circumstances. This can be done using LANconfig in the device configuration under Wireless LAN > WLC.

Operating with WLC: This configures whether an access point actively searches for a WLC and can be managed by one.
Note: This option should be deactivated for operation in stand-alone mode.
Port: Configures the port used to attempt to reach a WLC. The default value of 1027 is the default port used by the CAPWAP protocol. By default, R&S®NC WLCs also use this port.
Update certificate before: Configures how many days before its expiry that the device certificate used by the access point to authenticate at the WLC is renewed.
WLAN Controller: Configures user-specified WLAN controllers. This may be necessary if a WLC cannot be found via the local network (e.g. with routed connections) and also the DNS name "WLC-Address" cannot be used to inform the access point about the address of the WLC.
