How to Configure a Switch Cluster

This section describes how to configure the Cisco EtherSwitch service module in a cluster. This section assumes you have already connected the Cisco EtherSwitch service modules to each other.

A switch cluster comprises up to 16 connected, cluster-capable Cisco EtherSwitch service modules or Catalyst switches that are managed as a single entity. The Cisco EtherSwitch service modules in the cluster use the switch clustering technology so that you can configure and troubleshoot a group of different service modules or Catalyst switches through a single IP address.

In a switch cluster, 1 member must be the cluster command switch, and up to 15 other Cisco EtherSwitch service modules or switches can be cluster member switches. The total number of service modules or switches in a cluster cannot exceed 16. The cluster command service module or switch is the single point of access used to configure, manage, and monitor the cluster member service modules or switches. Cluster members can belong to only one cluster at a time.

You can enable a cluster command Cisco EtherSwitch service module, name the cluster, and assign an IP address and a password to the cluster command service module when you run the setup program during initial Cisco EtherSwitch service module setup.

Note Using Network Assistant to create a cluster is easier than using the CLI commands.

Note If you did not enable a cluster command service module during initial Cisco EtherSwitch service module setup, launch Device Manager from a command-capable Cisco EtherSwitch service module, and choose Cluster > Create Cluster. Enter a cluster number (the default is 0), and use up to 31 characters to name the cluster. Instead of using Network Assistant to enable a cluster command service module, you can use the cluster enable global configuration command.
