2.2.2 Configuring Member Devices

I. Member device configuration task list
Complete the following tasks to configure the member device:
Enabling NDP globally and on specific ports
Enabling NTDP globally and on a specific port
Enabling the cluster function
Accessing the shared FTP/TFTP server from a member device
Note:
To reduce the risk of being attacked by malicious users against opened socket and
enhance switch security, the S3100-52P Ethernet switch provides the following
functions, so that a cluster socket is opened only when it is needed:
Opening UDP port 40000 (used for cluster) only when the cluster function is
implemented,
Closing UDP port 40000 at the same time when the cluster function is closed.
On member devices, the preceding functions are implemented as follows:
When you execute the add-member command on the management device to add a
candidate device to a cluster, the candidate device changes to a member device
and its UDP port 40000 is opened at the same time.
When you execute the auto-build command on the management device to have
the system automatically add candidate devices to a cluster, the candidate devices
change to member devices and their UDP port 40000 is opened at the same time.
When you execute the administrator-address command on a device, the device's
UDP port 40000 is opened at the same time.
When you execute the delete-member command on the management device to
remove a member device from a cluster, the member device's UDP port 40000 is
closed at the same time.
When you execute the undo build command on the management device to remove
a cluster, UDP port 40000 of all the member devices in the cluster is closed at the
same time.
When you execute the undo administrator-address command on a member
device, UDP port 40000 of the member device is closed at the same time.
II. Enabling NDP globally and on specific ports
Follow these steps to enable NDP globally and on specific ports:
