The LANCOM High Availability Clustering Option offers you greatly simplified administration and significant time savings. You only have to configure one device in a set group of devices (cluster). The changes are automatically transferred to the other devices in the cluster.
If a device should fail or undergo maintenance (e.g. a firmware update), the APs automatically connect to another WLC or the established VPNs automatically connect to the backup central-site VPN gateway, as applicable. The automatic configuration synchronization mean that these devices already share an identical configuration. The result is a convenient way to high availability.
The prerequisites for a device to be a valid member of a cluster are:
- The LANCOM WLC High Availability Clustering XL Option (as of LCOS version 9.10).
- All cluster members must be able to establish IP communications via LAN, WAN or VPN.
- It must be in the list of group members that is stored in each device.
- It must have a valid certificate.
- It must be able to authenticate itself as a member of the cluster by certificate.
