SWITCH CLUSTERING
Switch 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.
COMMAND USAGE
◆ A switch cluster has a “Commander” unit that is used to manage all
other “Member” switches in the cluster. The management station can
use either Telnet or the web interface to communicate directly with the
Commander through its IP address, and then use the Commander to
manage Member switches using the cluster’s “internal” IP addresses.
◆ Clustered switches must be in the same Ethernet broadcast domain. In
other words, clustering only functions for switches which can pass
information between the Commander and potential Candidates or
active Members through VLAN 4093.
◆ Once a switch has been configured to be a cluster Commander, it
automatically discovers other cluster-enabled switches in the network.
These “Candidate” switches only become cluster Members when
