How to separate cluster running in EAP domain mode ?

Issue

• How to separate cluster running in domain mode ?
• How can I separate clusters running in a domain if I use the same socket-binding-group?
• Different servers in a domain with an 'ha' profile run within the same cluster at runtime, how can I avoid that?
• I see that different servers of my domain build a cluster but this is not intentional, what is the reason?
• I would like to know how to change in domain mode the port of the jgroups in the server groups, since the groups in ha are currently running in the same cluster.
