There are a couple of fields relating to clustering in the Network Interface management screen.

To get to this screen, go to System Configuration > Network Setup in the main menu of the LoadMaster WUI and click one of the interfaces. The cluster-related options are described below.

Cluster Shared IP address

Specify the shared IP address which can be used to access the cluster. This is also used as the default source address when using Server NAT.

Use for Cluster checks

Use this option to enable cluster health checking between the admin LoadMaster and the nodes. At least one interface must be enabled.

Use for Cluster Updates

Select this option to use this interface to synchronize the configuration with all of the other nodes in the cluster.
