HGMP V2 has the following advantages:
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.
It provides the topology discovery and display function, which assists in monitoring
and maintaining the network.
It allows you to configure and upgrade multiple switches at the same time.
It enables you to manage your remotely devices conveniently regardless of
network topology and physical distance.
It saves IP address resource.

2.1.2 Roles in a Cluster

The switches in a cluster play different roles according to their functions and status. You
can specify the role a switch plays. A switch in a cluster can also switch to other roles
under specific conditions.
As mentioned above, the three cluster roles are management device, member device,
and candidate device.
