To display the current states of the networks you can use get-clusternetwork cmdlet in PowerShell
Or you can open Failover Cluster Manager and select Networks at the left panel
Select a network and then at the right panel click Properties.
Here you can choose if the network will be used for cluster, client communication or no communication at all.
With get-clusterNetwork, you can also configure the above setting.
(get-clusteNetwork "Cluster Network 1").name = "CNET 1" # change the name
(get-clusteNetwork "Cluster Network 2").role = 0 # change the role propertie # 0 = disabled for cluster communication # 1 = enabled for cluster communitation only # 2 = enabled for cluster and client communication
