Manually Collecting Topology Information; Enabling The Cluster Function; Establishing A Cluster - HP A3100-8 v2 EI Configuration Manual

NOTE:
The two delay values should be configured on the topology collecting device. A topology-collection
request sent by the topology collecting device carries the two delay values, and a device that receives the
request forwards the request according to the delays.

Manually collecting topology information

The management switch collects topology information periodically after a cluster is created. In addition,
you can manually start topology information collection on the management switch or NTDP-enabled
device, managing and monitoring devices in real time, regardless of whether a cluster is created.
Follow these steps to configure to manually collect topology information:
To do...
Manually collect topology
information

Enabling the cluster function

To do...
Enter system view
Enable the cluster function globally

Establishing a cluster

As shown in the steps below, establishing a cluster includes the following preparation:
• Specify the management VLAN. (You cannot modify the management VLAN after a device is
added to the cluster.)
On the device to be configured as the management switch, configure a private IP address pool for
•
the devices to be added to the cluster.
The IP addresses of the VLAN interfaces of the management switch and member switches cannot be in
the same network segment as that of the cluster address pool, or the cluster cannot work normally. When
a candidate switch is added to a cluster, the management switch 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. You can follow the prompts to
establish a cluster automatically. The system cluster auto-establishment process will prompt you through
the following steps:
• Enter a name for the cluster you want to establish.
List all the candidate switches within your predefined hop count.
•
• Start 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 establish a cluster manually or automatically:
Use the command...
ntdp explore
Use the command...
system-view
cluster enable
