Operation Manual – Cluster
Quidway S3900 Series Ethernet Switches-Release 1510
Note:
To protect the unused sockets against malicious attacks and improve the switch
security, S3900 series Ethernet switches provide the following function:
When the cluster function is enabled, socket UDP 40000 used by the cluster is
enabled;
When the cluster function is disabled, socket UDP 40000 is disabled at the same
time.
This function is implemented on the member switch in the following scenarios:
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.
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.
Use the administrator-address command on the current switch to enable socket
UDP 40000.
Use the delete-member command on the management device to delete a cluster
member and disable socket UDP 40000 of the member switch.
Use the undo build command on the management device to delete a cluster and
disable sockets UDP 40000 of all the cluster members.
Use the undo administrator-address command on a member switch to disable
socket UDP 40000 of the member switch.
