Clustering Switches
This chapter provides these topics to help you get started with switch clustering:
•Understanding Switch Clusters, page 7-2
•Planning a Switch Cluster, page 7-5
•Creating a Switch Cluster, page 7-18
•Using the CLI to Manage Switch Clusters, page 7-23
•Using SNMP to Manage Switch Clusters, page 7-24
Configuring switch clusters is more easily done from the Cluster Management Suite (CMS) web-based
interface than through the command-line interface (CLI). Therefor e, information in this chapter focuses
on using CMS to create a cluster. See Chapter4, “Getting Started with CMS,” for additional information
about switch clusters and the clustering options. For complete procedu res about 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 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, for t he required software
versions, and for the browser and Java plug-in configurations.
Note This chapter focuses on Catalyst2950 and Catalyst 2955 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.
