Hello James, The way to do it is to assign a new MAC pool range to this cluster and then to remove it. This can be done via - Administration > Configure > MAC addresses pool - There you can create/edit and remove MAC pool range entities. So create another desired MAC pool range, assign it to the cluster(via edit cluster) and remove the desired MAC pool range from the system.
