IP Cluster Commands
4-325
4
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 a single IP subnet (Layer 2 domain).
• 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.
Syntax
[no] cluster commander
Default Setting
Disabled
Command Mode
Global Configuration
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 using 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
