To reduce the risk of being attacked by malicious users against opened socket and enhance switch
security, the S5100 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.
