Chapter 5 Clustering Switches Creating a Switch Cluster Adding Cluster Member Switches As explained in the "Automatic Discovery of Cluster Candidates and Members" section on page 5-5, the cluster command switch automatically discovers candidate switches. When you add new cluster-capable switches to the network, the cluster command switch discovers them and adds them to a list of candidate switches. To display an updated cluster candidates list from the Add to Cluster window (Figure 5-9), either relaunch CMS and redisplay this window, or follow these steps: 1. Close the Add to Cluster window. 2. Select View > Refresh. 3. Select Cluster > Add to Cluster to redisplay the Add to Cluster window. From CMS, there are two ways to add switches to a cluster: • Select Cluster > Add to Cluster, select a candidate switch from the list, click Add, and click OK. To add more than one candidate switch, press Ctrl, and make your choices, or press Shift, and choose the first and last switch in a range. • Display the Topology view, right-click a candidate-switch icon, and select Add to Cluster (Figure 5-10). In the Topology view, candidate switches are cyan, and cluster member switches are green. To add more than one candidate switch, press Ctrl, and left-click the candidates that you want to add. Instead of using CMS to add members to the cluster, you can use the cluster member global configuration command from the cluster command switch. Use the password option in this command if the candidate switch has a password. You can select 1 or more switches as long as the total number of switches in the cluster does not exceed 16 (this includes the cluster command switch). 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 switch before adding a new one. If a password has been configured on a candidate switch, you are prompted to enter it before it can be added it to the cluster. If the candidate switch does not have a password, any entry is ignored. If multiple candidates switches have the same password, you can select them as a group, and add them at the same time. If a candidate switch in the group has a password different from the group, only that specific candidate switch is not added to the cluster. When a candidate switch joins a cluster, it inherits the command-switch password. For more information about setting passwords, see the "Passwords" section on page 5-14. For additional authentication considerations in switch clusters, see the "TACACS+ and RADIUS" section on page 5-14. 78-16156-01 Catalyst 3560 Switch Software Configuration Guide 5-17
