1-7z Disabling the NDP and NTDP functions on the management device and member devices after acluster is created will not cause the cluster to be dismissed, but will influence the normal operationof the cluster.z When both the cluster function and the 802.1x function (or the MAC address authentication) areenabled on devices, you need to enable HABP on the devices. Otherwise, the management deviceof the cluster cannot manage the devices connected with it. For description of HABP, refer to HABPConfiguration in the Security Volume.z If the routing table of the management device is full when a cluster is established, that is, entrieswith the destination address as a candidate device cannot be added to the routing table, allcandidate devices will be added to and removed from the cluster repeatedly.z If the routing table of a candidate device is full when the candidate device is added to a cluster, thatis, the entry with the destination address as the management device cannot be added to the routingtable, the candidate device will be added to and removed from the cluster repeatedly.Configuring the Management DeviceEnabling NDP Globally and for Specific PortsFor NDP to work normally, you must enable NTDP both globally and on specific ports.Follow these steps to enable NDP globally and for specific ports:To do… Use the command… RemarksEnter system view system-view —Enable NDP globally ndp enable OptionalEnabled by default.In systemview ndp enable interfaceinterface-listinterface interface-typeinterface-numberEnable theNDP featurefor the port(s)In Ethernetport view orLayer 2aggregateinterface view ndp enableUse either commandBy default, NDP is enabledglobally and also on all ports.You are recommended to disable NDP on the port which connects with the devices that do not need tojoin the cluster, preventing the management device from adding the device which needs not to join thecluster and collecting the topology information of this device.
