Switch Clustering
– 184 –
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 16 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
Console(config)#cluster
Console(config)#
cluster commander This command enables the switch as a cluster Commander. Use the no form to
disable the switch as cluster Commander.
Syntax
[no] cluster commander

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.
Example
Console(config)#cluster commander
Console(config)#
