Left Pane—Groups List
You can create groups of nodes using the topology map and the Layout menu. Once you have groups in your topology, the Groups list in the left pane of the Topology view shows all your node groups, and lists all nodes not included in any group under the heading UNGROUPED.
When you expand a group listing using the plus (+) sign next to the group name, all the member nodes are listed. When you collapse a group listing using the minus sign (-), only the group name appears. In Figure 1, Group1 and UNGROUPED are expanded, and Group 2 is collapsed.
The topology map reflects the expansion and collapse of the groups in the groups list. For an expanded group, all individual nodes are displayed in the topology map, without indication of which group they belong to. For a collapsed group, the individual node icons are collectively represented by a group icon. Hover over or click on the group icon in the map to display the group name. If you collapse UNGROUPED in the Groups list, the nodes disappear from the topology map. Figure 2 shows the arrangement from Figure 1 along with the corresponding topology map.
