1-8Configuring NDP ParametersA port enabled with NDP periodically sends NDP packets to its neighbors. If no NDP information fromthe neighbor is received when the holdtime times out, the corresponding entry is removed from the NDPtable.Follow these steps to configure NDP parameters:To do… Use the command… RemarksEnter system view system-view —Configure the interval forsending NDP packets ndp timer hello hello-time Optional60 seconds by default.Configure the period for thereceiving device to keep theNDP packetsndp timer aging aging-time Optional180 seconds by default.The time for the receiving device to hold NDP packets cannot be shorter than the interval for sendingNDP packets; otherwise, the NDP table may become instable.Enabling NTDP Globally and for Specific PortsFor NTDP to work normally, you must enable NTDP both globally and on specific ports.Follow these steps to enable NTDP globally and for specific ports:To do… Use the command… RemarksEnter system view system-view —Enable NTDP globally ntdp enable OptionalEnabled by defaultinterface interface-typeinterface-numberEnable NTDP for the portntdp enableOptionalNTDP is enabled on all ports bydefault.You are recommended to disable NTDP 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.Configuring NTDP ParametersBy configuring the maximum hops for collecting topology information, you can get topology information
