27 CLUSTER CONFIGURATION GUIDE
Cluster Configuration The cluster function is implemented through 3Com Group Management Protocol
version 2 (Switch Clusteringv2). Using Switch Clusteringv2, you can manage
multiple switches through the public IP address of a master device. In a cluster, the
master switch is called the management device, and the managed switches are
called member devices. The member devices are not configured with public IP
addresses. They are managed and maintained through the management device
redirection.

Three switches form a cluster, where:
■A Switch 5500 serves as the management device.
■The other two switches are member devices.
Serving as the management device, the Switch 5500 manages the two member
devices. The configurations for the cluster are as follows:
■The two member devices are connected to Ethernet 1/0/2 and Ethernet 1/0/3
of the management device.
■The management device connects to the Internet through Ethernet 1/0/1.
