318 CHAPTER 30: CLUSTER
Figure 99 A cluster implementation
Switch Clustering 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.
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.
