Cluster Management Overview

Cluster Management Definition

A cluster is a group of network devices. Cluster management is to implement management of large
numbers of distributed network devices. Cluster management offers the following advantages:
Saving public IP address resource
Simplifying configuration and management tasks. By configuring a public IP address on one device,
you can configure and manage a group of devices without the trouble of logging in to each device
separately.
Providing topology discovery and display function, which is useful for network monitoring and
debugging
Allowing simultaneous software upgrading and parameter configuration on multiple devices, free of
topology and distance limitations

Roles in a Cluster

The devices in a cluster play different roles according to their different functions and status. You can
specify the following three roles for the devices:
Management device (Administrator): The device providing management interfaces for all devices
in a cluster and the only device configured with a public IP address. You can specify one and only
one management device for a cluster. Any configuration, management, and monitoring of the other
devices in a cluster can only be implemented through the management device. When a device is
specified as the management device, it collects related information to discover and define
candidate devices.
Member device (Member): A device managed by the management device in a cluster.
Candidate device (Candidate): A device that does not belong to any cluster but can be added to a
cluster. Different from a member device, its topology information has been collected by the
management device but it has not been added to the cluster.
