Cluster Configuration Task List
Before configuring a cluster, you need to determine the roles and functions the switches play. You also
need to configure the related functions, preparing for the communication between devices within the
cluster.
Complete the following tasks to configure cluster:
Task Remarks
Configuring the Management Device Required
Configuring Member Devices Required
Managing a Cluster through the Management Device Optional
Configuring the Enhanced Cluster Features Optional
Configuring the Cluster Synchronization Function Optional
Configuring the Management Device
Management device configuration task list
Complete the following tasks to configure management device:
Task Remarks
Enabling NDP globally and on specific ports Required
Configuring NDP-related parameters Optional
Enabling NTDP globally and on a specific port Required
Configuring NTDP-related parameters Optional
Enabling the cluster function Required
Configuring cluster parameters Required
Configuring inside-outside interaction for a cluster Optional
Configuring the network management interface for a cluster Optional
To reduce the risk of being attacked by malicious users against opened socket and enhance switch
security, the S3600 series Ethernet switches provide the following functions, 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 is implemented,
z Closing UDP port 40000 at the same time when the cluster function is closed.
On the management device, the preceding functions are implemented as follows:
z When you create a cluster by using the build or auto-build command, UDP port 40000 is opened
at the same time.
z When you remove a cluster by using the undo build or undo cluster enable command, UDP port
40000 is closed at the same time.
