Command Usage
• To create a switch cluster, first be sure that clustering is enabled on the switch (the
default is enabled), then set the switch as a Cluster Commander. Set a Cluster IP
Pool that does not conflict with any other IP subnets in the network. Cluster IP
addresses are assigned to switches when they become Members and are used for
communication between Member switches and the Commander.
• Switch clusters are limited to the same Ethernet broadcast domain.
• There can be up to 100 candidates and 36 member switches in one cluster.
• A switch can only be a Member of one cluster.
• Configured switch clusters are maintained across power resets and network changes.
Example
cluster commander
This command enables the switch as a cluster Commander. Use the no form to disable
the switch as cluster Commander.

Command Mode

Command Usage
• 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 manually selected by the
administrator through the management station.
• Cluster Member switches can be managed through a Telnet connection to the
Commander. From the Commander CLI prompt, use the rcommand id command to
connect to the Member switch.

Console(config)#cluster
