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
