ref

none 

References the name attribute of a cluster element.

self-loadbalance

true

(optional) If true, specifies that a configured cluster load balances incoming requests to itself. If true, the parent converged-lb-config element must have exactly one converged-lb-cluster-ref subelement. In this case, the load balancer is an intrinsic component of the participating server instances in the cluster.

For production environments, only the true setting is supported.
