A management devicecollects NDP/NTDP information to discover and determine candidate devices,which can be then added into the cluster through manual configurations.z A candidate device becomes a member device after being added to a cluster.z A member device becomes a candidate device after being removed from thecluster.1.2 Management Device Configuration1.2.1 Management Device Configuration Task ListComplete the following tasks to configure the management device:Task RemarksEnabling NDP Globally and for Specific Ports RequiredConfiguring NDP-Related Parameters RequiredEnabling NTDP Globally and for Specific Ports Required
