CLUSTER CONFIGURATION
Cluster Overview
Introduction to Cluster A cluster is implemented through HGMP V2. By employing HGMP V2, a network
administrator can manage multiple switches using the public IP address of a switch
known as a management device. The switches under the management of the
management device are member devices. The management device, along with the
member devices, forms a cluster. Normally, a cluster member device is not assigned a
public IP address. Management and maintenance operations intended for the
member devices in a cluster are redirected by the management device. Figure 83
illustrates a typical cluster implementation.

HGMP V2 offers the following advantages:
■ The procedures to configure multiple switches remarkably simplified. When the
management device is assigned a public IP address, you can configure/manage a
specific member device on the management device instead of logging into it in
advance.
■ Functions of topology discovery and display provided, which assist network
monitoring and debugging
■ Software upgrading and parameter configuring can be performed simultaneously
on multiple switches.
■ Free of topology and distance limitations
■ Saving IP address resource
