How to Configure a Switch Cluster

Adding Cluster Members to the Cisco EtherSwitch Service Module

This section shows how to add cluster members to the Cisco EtherSwitch service module.

The cluster command service module or switch automatically discovers candidate Cisco EtherSwitch service modules or switches. When you add new cluster-capable switch service modules or switches to the network, the cluster command service module or switch discovers them and adds them to a list of candidate service modules or switches.

Note A switch stack in a cluster equates to a single cluster member. There is a restriction specific to adding

cluster members through Network Assistant. From Network Assistant, you can create a Cisco EtherSwitch service module or switch cluster with up to 15 cluster members. From Network Assistant or the CLI, you can create a Cisco EtherSwitch service module or switch cluster with up to 144 devices.

Note You can add 1 or more Cisco EtherSwitch service modules as long as the total number of service modules in the cluster does not exceed 16 (this includes the cluster command service module). When a cluster has 16 members, the Add to Cluster option is not available for that cluster. In this case, you must remove a cluster member service module before adding a new one.

If a password has been configured on a candidate Cisco EtherSwitch service module or switch, you are prompted to enter it before the service module or switch can be added to the cluster. If the candidate Cisco EtherSwitch service module switch does not have a password, any entry is ignored.

If multiple candidate Cisco EtherSwitch service modules or switches have the same password, you can choose them as a group, and add them at the same time.

If a candidate Cisco EtherSwitch service module or switch in the group has a password different from that of the group, only that specific candidate service module or switch is not added to the cluster.

When a candidate service module or switch joins a cluster, it inherits the command service module or switch password.

Prerequisites

Network Assistant must be enabled.

SUMMARY STEPS

Use these steps from the Network Assistant application.

1.Close the Add to Cluster window.

2.Choose View > Refresh.

3.Choose Cluster > Add to Cluster or

Choose Add to Cluster by displaying the Topology view and right-clicking a candidate service module icon.

Instead of using Network Assistant, you can use these commands from the CLI:

1.cluster member [n] mac-address H.H.H [password enable-password] [vlan vlan-id]

2.password enable-password
