Clustering Switches
This chapter provides these topics to help you get started with switch clustering:
• Understanding Switch Clusters, page 5-2
• Planning a Switch Cluster, page 5-5
• Creating a Switch Cluster, page 5-19
• Using the CLI to Manage Switch Clusters, page 5-26
• Using SNMP to Manage Switch Clusters, page 5-27
Configuring switch clusters is more easily done from the Cluster Management Suite (CMS) web-based
interface than through the command-line interface (CLI). Therefore, information in this chapter focuses
on using CMS to create a cluster. See Chapter 2, “Getting Started with CMS,” for additional information
about switch clusters and the clustering options. For complete procedures on using CMS to configure
switch clusters, refer to the online help.
For the CLI cluster commands, refer to the switch command reference.
Refer to the release notes (http://www.cisco.com/univercd/cc/td/doc/product/lan/c2900xl/index.htm) for
the list of Catalyst switches eligible for switch clustering, including which ones can be command
switches and which ones can only be member switches, and for the required software versions and
browser and Java plug-in configurations.
Note This chapter focuses on Catalyst 2900 XL and Catalyst 3500 XL switch clusters. It also includes
guidelines and limitations for clusters mixed with other cluster-capable Catalyst switches, but it does not
provide complete descriptions of the cluster features for these other switches. For complete cluster
information for a specific Catalyst platform, refer to the software configuration guide for that switch.
