  Note: 
To protect the unused sockets against malicious attacks and improve the switch 
security, S3900 series Ethernet switches provide the following function: 
z  When the cluster function is enabled, socket UDP 40000 used by the cluster is 
enabled;  
z  When the cluster function is disabled, socket UDP 40000 is disabled at the same 
time.  
This function is implemented on the command switch in the following scenarios: 
z  Use the build command or the auto-build command to create a cluster and enable 
socket UDP 40000 used by the cluster at the same time.  
z  Use the undo build command or the undo cluster enable command to remove a 
cluster and disable socket UDP 40000 at the same time.  
This function is implemented on the member switch in the following scenarios: 
z  Use the add-member command on the management device to add a candidate 
switch into the cluster and enable socket UDP 40000 of the new member. 
z  Use the auto-build command on the management device to add a candidate switch 
into the cluster and enable socket UDP 40000 of the new member. 
z  Use the administrator-address command on the current switch to enable socket 
UDP 40000.  
z  Use the delete-member command on the management device to delete a cluster 
member and disable socket UDP 40000 of the member switch.  
z  Use the undo build command on the management device to delete a cluster and 
disable sockets UDP 40000 of all the cluster members.  
z  Use the undo administrator-address command on a member switch to disable 
socket UDP 40000 of the member switch.
