 lists the cluster capabilities and Cisco IOS releases for the 

switches. The switches are listed from the highest to lowest end. 

If you are managing the cluster through CMS, the switch that has the latest software should be the 
command switch, unless your command switch is running Cisco IOS Release 12.1(19)EA1 or later.

The standby command switch must be the same type as the command switch. For example, if the 
command switch is a Catalyst 3750 switch, all standby command switches must be Catalyst 3750 
switches.
