Cisco Cisco IOS Software Release 12.2(53)SE

You cannot create and manage switch clusters through the device manager. To create and manage switch 
clusters, use the command-line interface (CLI) or the Network Assistant application. 

When creating a switch cluster or adding a switch to a cluster, follow these guidelines:

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

If you are managing the cluster through Network Assistant, the switch with the latest software 
should be the command switch. 

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

For additional information about clustering, see Getting Started with Cisco Network Assistant, Release 
Notes for Cisco Network Assistant, the Cisco enhanced EtherSwitch service module documentation, the 
software configuration guide, and the command reference.

Cisco IOS 12.2(53)SE2 will be supported in a future release of the Cisco Network Assistant. You can 
download Cisco Network Assistant from this URL:
