When an NTDP topology collection request is propagated in the network, it is received
and forwarded by large numbers of network devices, which may cause network
congestion and the management device busy processing of the NTDP topology
collection responses. To avoid such cases, the following methods can be used to
control the NTDP topology collection request advertisement speed.
Configuring the devices not to forward the NTDP topology collection request
immediately after they receive an NTDP topology collection request. That is,
configure the devices to wait for a period before they forward the NTDP topology
collection request.
Configuring each NTDP-enabled port on a device to forward an NTDP topology
collection request after a specific period since the previous port on the device
forwards the NTDP topology collection request.
Note:
To implement NTDP, you need to enable NTDP both globally and on specific ports
on the management device, and configure NTDP parameters.
On member/candidate devices, you only need to enable NTDP globally and on
specific ports.
Member and candidate devices adopt the NTDP settings of the management
device.
III. Introduction to Cluster
A cluster must have one and only one management device. Note the following when
creating a cluster:
You need to designate a management device for the cluster. The management
device of a cluster is the portal of the cluster. That is, any operations from outside
the network intended for the member devices of the cluster, such as accessing,
configuring, managing, and monitoring, can only be implemented through the
management device.
The management device of the cluster recognizes and controls all the member
devices in the cluster, no matter where they are located in the network and how
they are connected.

member/candidate devices to provide useful information for you to establish the
cluster.
By collecting NDP/NTDP information, the management device learns network
topology, so as to manage and monitor network devices.
