Disabling the NDP and NTDP functions on the management device and member devices after a
cluster is created will not cause the cluster to be dismissed, but will influence the normal operation
of the cluster.
z
When both the cluster function and the 802.1x function (or the MAC address authentication) are
enabled on devices, you need to enable HABP on the devices. Otherwise, the management device
of the cluster cannot manage the devices connected with it. For description of HABP, refer to
HABP
Configuration
in the
Security Volume
.
z
If the routing table of the management device is full when a cluster is established, that is, entries
with the destination address as a candidate device cannot be added to the routing table, all
candidate devices will be added to and removed from the cluster repeatedly.

Configuring the Management Device
Enabling NDP Globally and for Specific Ports
For NDP to work normally, you must enable NTDP both globally and on specific ports.
Follow these steps to enable NDP globally and for specific ports:
To do…
Use the command…
Remarks
Enter system view

—
Enable NDP globally
ndp enable
Optional
Enabled by default.
In system

ndp enable interfaceinterface-list
interface interface-type

for the port(s)
In Ethernet

ndp enable
Use either command
By default, NDP is enabled
globally and also on all ports.
You are recommended to disable NDP on the port which connects with the devices that do not need to
join the cluster, preventing the management device from adding the device which needs not to join the
cluster and collecting the topology information of this device.
