Manually collecting topology information
The management device collects topology information periodically after a cluster is created. In addition,
you can configure to manually initiate topology information collection on the management device or
NTDP-enabled device, thus managing and monitoring devices in real time, regardless of whether a
cluster is created.
To configure to manually collect topology information:
Task Command Remarks
Manually collect topology
information.

Enabling the cluster function
Step Command Remarks
120. Enter system view. system-view N/A
Optional. 121. Enable the cluster function
globally.
cluster enable
By default, this function is enabled.
Establishing a cluster
To successfully establish a cluster:
• Make sure UDP port 40000 is not used by any application. This port will be used by the cluster
management module for exchanging handshake packets.
• Perform the following tasks before establishing the cluster:
{
Specify a management VLAN. You cannot change the management VLAN after a cluster is
created.
{
Configure a private IP address pool on the management device for cluster member devices. This
address pool must not include IP addresses that are on the same subnet as the IP address
assigned to any VLAN interface on the management device or a cluster candidate device.
When a candidate device is added to the cluster, the management device assigns it a private
IP address for inter-cluster communication.
A cluster can be established manually or automatically. Using the automatic setup method:
1. You enter a name for the cluster you want to establish.
2. The system lists all candidate devices within your predefined hop count.
3. The system starts to add them to the cluster.
During this process, you can press Ctrl+C to stop the process. However, devices already added
into the cluster are not removed.
