Upgrade for high-availability device clusters
Large networks with many devices have particularly high availability requirements: With the LANCOM High Availability Clustering Option, you can combine up to 10 WLAN controllers, SD-WAN central site gateways and SD-WAN Gateways into a high-availability device cluster and conveniently manage these clusters together, even in the case of multi-site networks.

Advantages
Central management and configuration synchronization
Group several WLAN controllers, SD-WAN central site gateways, or SD-WAN gateways to a high-availability cluster! With the LANCOM High Availability Clustering Options you can combine several devices to one cluster. As a consequence, there are many advantages like the central management and convenient configuration alignment (Config Sync) of all cluster devices.

Increased time savings and safety
Grouping devices into device clusters makes it easier to build intelligent backup scenarios since only one WLAN controller, SD-WAN central site gateway or SD-WAN gateway has to be configured – an enormous time saver for administrators. Furthermore, you benefit from an automatic load balancing and the enrollment of cluster certificates.

Easy upgrades
The LANCOM software options turn a simple network into a customized and cost-efficient solution that meets your individual needs. Simply install them on your existing hardware and you upgrade your network with the desired feature. The advantage: No additional hardware components are required. The costs and the administration overhead of the entire network are reduced. Genuine added value comes in terms of the system's future viability, because the options transform a network into a customized and scalable networking solution.

Scenarios
LANCOM WLC High Availability Clustering XL Option
This software option allows multiple WLCs to be grouped into a highly-available cluster. In this way, configuration changes, features and enhancements made on one WLC are automatically transferred between the other WLCs in the cluster, without having to make manual changes on each individual device. Common parameters in a cluster (e.g. WLAN profiles or AP tables) remain synchronized, individual parameters (such as the IP address of the WLC) are not exchanged.

LANCOM VPN High Availability Clustering L / XL Option
This option allows multiple central-site VPN gateways or SD-WAN gateways to be grouped into a cluster. In this way, configuration changes, features and enhancements made on one device are automatically transferred between the cluster devices, without having to make manual changes on each individual device. Common parameters in a cluster (e.g. VPN user database, firewall) remain synchronized, individual parameters (such as the IP address) are not exchanged.
