System Requirements
Cluster Compatibility
This section describes how to choose command and standby command switches when a cluster consists
of a mixture of Catalyst switches. When creating a switch cluster or adding a switch to a cluster, follow
these guidelines:

these guidelines:
•
When you create a switch cluster, we recommend configuring the highest-end switch in your cluster
as the command switch.

lists the cluster capabilities and Cisco IOS releases for the switches.
The switches are listed from highest- to lowest-end switch.
•
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.
