Cluster Configuration
Tasks
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.

To reduce the risk of being attacked by malicious users against opened socket and
enhance switch security, the Switch 4210 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 the management device, the preceding functions are implemented as follows:
■
When you create a cluster by using the build or auto-build command, UDP
port 40000 is opened at the same time.
■
When you remove a cluster by using the undo build or undo cluster enable
command, UDP port 40000 is closed at the same time.
