IP Clustering is a method of grouping switches together to enable centralized
management through a single unit. Switches that support clustering can be grouped
together regardless of physical location or switch type, as long as they are
connected to the same local network.
A switch cluster has a “Commander” unit that is used to manage all other “Member”
switches in the cluster. The management station can use both Telnet and the web
interface to communicate directly with the Commander throught its IP address, while
the Commander manages Member switches using cluster “internal” IP addresses.
There can be up to 36 Member switches in one cluster, and Cluster switches must
be in the same IP subnet.
Once a switch has been configured to be a cluster Commander, it automatically
discovers other cluster-enabled switches in the network. These “Candidate”
