1.1 Cluster Overview
1.1.1 Introduction to HGMP V2
The cluster function is implemented through Huawei group management protocol
version 2 (HGMP V2). With HGMP V2, a network administrator can manage multiple
switches through the public IP address of a switch known as a management device.
The managed switches under the management device are called member devices. The
management device and the member devices together compose a cluster. Normally,
member devices do not have public IP addresses, but you can manage and maintain
them through the management device, which can redirect your management and
maintenance operations to their intended destinations. Figure 1-1 illustrates a typical
cluster application.

HGMP V2 has the following advantages:
z
It eases the configuration and management of multiple switches: You just need to
configure a public IP address for the management device instead of for all the
devices in the cluster; and then you can configure and manage all the member
devices through the management device without the need to log onto them one by
one.
