3 Switch Clustering Once a switch has been configured to be a cluster Commander, it automatically discovers other cluster-enabled switches in the network. These "Candidate" switches only become cluster Members when manually selected by the administrator through the management station. After the Commander and Members have been configured, any switch in the cluster can be managed from the web interface by choosing the Member ID from the Cluster drop-down menu. From the Commander CLI prompt, use the "rcommand" command (see 4-240) to connect to the Member switch. Figure 3-122 Cluster Member Choice Cluster Configuration To create a switch cluster, first be sure that clustering is enabled on the switch (the default is enabled), then set the switch as a Cluster Commander. Set a Cluster IP Pool that does not conflict with the network IP subnet. Cluster IP addresses are assigned to switches when they become Members and are used for communication between Member switches and the Commander. Command Attributes • Cluster Status - Enables or disables clustering on the switch. • Cluster Commander - Enables or disables the switch as a cluster Commander. • Role - Indicates the current role of the switch in the cluster; either Commander, Member, or Candidate. • Cluster IP Pool - An "internal" IP address pool that is used to assign IP addresses to Member switches in the cluster. Internal cluster IP addresses are in the form 10.x.x.member-ID. Only the base IP address of the pool needs to be set since Member IDs can only be between 1 and 16. Note that you cannot change the cluster IP pool when the switch is currently in Commander mode. Commander mode must first be disabled. • Number of Members - The current number of Member switches in the cluster. • Number of Candidates - The current number of Candidate switches discovered in the network that are available to become Members. 3-195
