Chapter 30 Cluster Commands
Cluster Management function enables a network administrator to manage the scattered devices in
the network via a management device. After a commander switch is configured, management and
maintenance operations intended for the member devices in a cluster is implemented by the
commander device.
cluster ndp
Description
The cluster ndp command is used to configure NDP globally. To return to the
default configuration, please use no cluster ndp command. NDP (Neighbor
Discovery Protocol) is used to discover the information of the directly connected
neighbor devices to support cluster establishing. An NDP-enabled device sends
NDP packets regularly to neighbor devices as well as receives NDP packets
from neighbor devices. An NDP packet carries the aging time, which indicates
the period of the receiving devices to keep the NDP packet.
