LCOS LX 5.32

Layer-3 tunneling for LCOS LX-based access points

With the new LCOS LX version 5.32 you now benefit from even more features and improvements for your LANCOM LX and LW devices. In addition to the management channel, LX-based access points now also support layer-3 tunneling for LANCOM WLAN controllers. Without the need for a VLAN infrastructure between WLAN controller and access point, data tunnels can be set up in a very short time to isolate the data traffic of individual SSIDs from each other.

Feature highlight

Layer-3 tunneling for LCOS LX-based access points

Layer-3 tunneling involves the extended application of the CAPWAP protocol (control and provisioning of wireless access points) as used by wireless LAN (WLAN) controllers to manage WLAN access points. It allows WLAN data to be fed into the LAN from a central WLAN controller by establishing a data tunnel between the WLAN controller and the access point. Layer-3 tunneling is ideal for environments where unmanaged switches are used or where no further VLAN configuration of the switches is possible. Data tunnels are established easily and in a very short time without the need for a VLAN infrastructure between WLAN controller and access point.

 

Note: To use this feature, the LANCOM WLAN controller requires LCOS 10.42 RU3.

Application scenario

Layer-3 tunneling for Wi-Fi guest access

A popular application of layer-3 tunneling is the establishment of wireless LAN guest access. Layer-3 tunneling guarantees the necessary level of security of guest accesses while reducing the administrative effort. Thus, the data traffic of a guest access is separated from the rest of the network. In contrast to having to configure all the components of the infrastructure when using VLAN, with layer-3 tunneling one only needs to ensure that the access points are connected to and managed by the WLAN controller. This is made possible by routing the hotspot SSID data through a layer-3 tunnel to the WLAN controller instead of feeding it directly into the local network at the access point (see figure below). There, the data can be received by the integrated Public Spot module, filtered by the optionally available Content Filter Option, and then routed to the Internet, for example.
