Establishing a Cluster
Before establishing a cluster, you need to specify the management VLAN, and you cannot modify the
management VLAN after a device is added to the cluster.
In addition, you need to configure a private IP address pool for the devices to be added to the cluster on
the device to be configured as the management device before establishing a cluster. Meanwhile, the IP
addresses of the VLAN interfaces of the management device and member devices cannot be in the
same network segment as that of the cluster address pool; otherwise, the cluster cannot work normally.
When a candidate device is added to a cluster, the management device assigns it a private IP address
for it to communicate with other devices in the cluster.
You can establish a cluster in two ways: manually and automatically. With the latter, you can establish a
cluster according to the prompt information. The system:
1) Prompts you to enter a name for the cluster you want to establish;
2) Lists all the candidate devices within your predefined hop count;
3) Starts to automatically add them to the cluster.
You can press
Ctrl+C
anytime during the adding process to exit the cluster auto-establishment process.
However, this will only stop adding new devices into the cluster, and devices already added into the
cluster are not removed.
Follow these steps to manually establish a cluster:
