Cluster Overview
Introduction to HGMP
A cluster contains a group of switches. Through cluster management, you can manage multiple
geographically dispersed in a centralized way.
Cluster management is implemented through Huawei Group Management Protocol (HGMP). HGMP
version 2 (HGMPv2) is used at present.
A switch in a cluster plays one of the following three roles:
z Management device
z Member device
z Candidate device
A cluster comprises of a management device and multiple member devices. To manage the devices in a
cluster, you need only to configure an external IP address for the management switch. Cluster
management enables you to configure and manage remote devices in batches, reducing the workload
of the network configuration. Normally, there is no need to configure external IP addresses for member
devices.
Figure 1-1 illustrates a cluster implementation.
