Operation Manual – Stack-ClusterH3C S3100-52P Ethernet Switch Chapter 2 Cluster2-162.2.2 Configuring Member DevicesI. Member device configuration task listComplete the following tasks to configure the member device:Task RemarksEnabling NDP globally and on specific ports RequiredEnabling NTDP globally and on a specific port RequiredEnabling the cluster function RequiredAccessing the shared FTP/TFTP server from a member device OptionalNote:To reduce the risk of being attacked by malicious users against opened socket andenhance switch security, the S3100-52P Ethernet switch provides the followingfunctions, so that a cluster socket is opened only when it is needed:z Opening UDP port 40000 (used for cluster) only when the cluster function isimplemented,z Closing UDP port 40000 at the same time when the cluster function is closed.On member devices, the preceding functions are implemented as follows:z When you execute the add-member command on the management device to add acandidate device to a cluster, the candidate device changes to a member deviceand its UDP port 40000 is opened at the same time.z When you execute the auto-build command on the management device to havethe system automatically add candidate devices to a cluster, the candidate deviceschange to member devices and their UDP port 40000 is opened at the same time.z When you execute the administrator-address command on a device, the device'sUDP port 40000 is opened at the same time.z When you execute the delete-member command on the management device toremove a member device from a cluster, the member device's UDP port 40000 isclosed at the same time.z When you execute the undo build command on the management device to removea cluster, UDP port 40000 of all the member devices in the cluster is closed at thesame time.z When you execute the undo administrator-address command on a memberdevice, UDP port 40000 of the member device is closed at the same time.II. Enabling NDP globally and on specific portsFollow these steps to enable NDP globally and on specific ports:
