Chapter 2 Catalyst 2950 and 2955 Cisco IOS Commands
cluster commander-address
cluster commander-address
You do not need to enter this command. The command switch automatically provides its MAC address
to member switches when these switches join the cluster. The member switch adds this information and
other cluster information to its running configuration file. Enter the no form of this global configuration
command from the member switch service port to remove it from a cluster only during debugging or
recovery procedures.
cluster commander-address mac-address [member number name name]
no cluster commander-address
Syntax Description
Defaults The switch is not a member of any cluster.
Command Modes Global configuration
Command History
Usage Guidelines A cluster member can have only one command switch.
The member switch retains the identity of the command switch during a system reload by using the
mac-address parameter.
You can enter the no form on a member switch to remove it from the cluster during debugging or
recovery procedures. You would normally use this command from the member switch consoleservice
port only when the member has lost communication with the command switch. With normal switch
configuration, we recommend that you remove member switches only by entering the no cluster
member n global configuration command on the command switch.
When a standby command-switch becomes active (becomes the command switch), it removes the cluster
commander-address line from its configuration.
Examples This is an example of text from the running configuration of a cluster member:

mac-address MAC address of the cluster command switch.
