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:
z Saving public IP address resource
z 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.
z Providing topology discovery and display function, which is useful for network monitoring and
debugging
z 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:
z 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.
z Member device (Member): A device managed by the management device in a cluster.
z 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.
