Operation Manual – Stack-ClusterH3C S3100 Series Ethernet Switches Chapter 2 Cluster2-1Chapter 2 Cluster2.1 Cluster Overview2.1.1 Introduction to HGMPA cluster contains a group of switches. Through cluster management, you can managemultiple 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 devicez Member devicez Candidate deviceA cluster comprises of a management device and multiple member devices. Tomanage the devices in a cluster, you need only to configure an external IP address forthe management switch. Cluster management enables you to configure and manageremote devices in batches, reducing the workload of the network configuration.Normally, there is no need to configure external IP addresses for member devices.Figure 2-1 illustrates a cluster implementation.Figure 2-1 A cluster implementationHGMP V2 has the following advantages:
