Cluster Management Overview
Cluster Management allows you to manage up to 24 switches through a single
IP to manage up to 24 switches simultaneously in the same broadcast domain
and the same VLAN group ID. The cluster manager which can manage other
switches is called the master device. The other terminology we use for cluster
management is “istacking”.
• How Cluster Management works
